Vendor score changes

November 2026 75 changes, 142 minor

1. November 6, 2026Ageless PeptidesDown 4.36 → 4.30 (-0.06)

   Lab evidence recomputed under the published rule on 6 November 2026: the list of the 15 products carried by the most vendors changed when new vendors were added (KLOW replaced sermorelin), which changes the weight of a missing certificate under rule A1b. Lab evidence 3.1 to 3.0.

2. November 6, 2026Amino ClubDown 8.08 → 8.02 (-0.06)

   The site claims ISO 17025 accredited testing, while ILS Laboratories, which issues every scored certificate, says there is no accreditation for its peptide testing (rule A7 CLAIM -0.1): lab 9.3 to 9.2.

3. November 6, 2026Arctic Lab SupplyDown 7.09 → 6.98 (-0.11)

   Lab score recomputed under the published rule on 6 November 2026: lab 6.2 to 6.0.

4. November 6, 2026Azyrion LabsUp 5.40 → 5.45 (+0.05)

   Lab evidence recomputed under the published rule on 6 November 2026: the list of the 15 products carried by the most vendors changed when new vendors were added (KLOW replaced sermorelin), which changes the weight of a missing certificate under rule A1b. Lab evidence 6.8 to 6.9.

5. November 6, 2026Bluum PeptidesDown 7.48 → 7.37 (-0.11)

   Five Horizon reports repeat analyses first reported to other businesses (rule A7 SUPPLIER -0.2): lab 8.3 to 8.1.

6. November 6, 2026BulkGLPDown 6.71 → 6.49 (-0.22)

   Lab score recomputed under the published rule on 6 November 2026: lab 7.9 to 7.5.

7. November 6, 2026Cernum BiosciencesDown 4.68 → 4.51 (-0.17)

   Coverage corrected on 6 November 2026. Eight products on sale were added: six with Janoshik reports confirmed at the laboratory, which were ordered by the manufacturer and are over 12 months old, and kisspeptin-10 and melanotan-1 with only a sheet issued by Cernum itself. Lab 4.9 to 4.6.

8. November 6, 2026Delix LabsUp 4.52 → 4.58 (+0.06)

   Lab evidence recomputed under the published rule on 6 November 2026: the list of the 15 products carried by the most vendors changed when new vendors were added (KLOW replaced sermorelin), which changes the weight of a missing certificate under rule A1b. Lab evidence 4.5 to 4.6.

9. November 6, 2026Drexa LabsDown 3.28 → 3.23 (-0.05)

   The site calls ILS Laboratories ISO 17025 accredited, while the laboratory says there is no accreditation for its peptide testing (rule A7 CLAIM -0.1): lab 1.3 to 1.2.

10. November 6, 2026FRO PeptidesDown 6.67 → 6.50 (-0.17)

    Lab evidence recomputed under the published rule on 6 November 2026: the SUPPLIER adjustment rose from 0.2 to 0.5 under rule A7 because 20 of its 21 Accumark certificates re-issue analyses first completed for other businesses, which is most of them. Lab evidence 7.3 to 7.0.

11. November 6, 2026GenX BioUp 4.39 → 4.45 (+0.06)

    Lab evidence recomputed under the published rule on 6 November 2026: the list of the 15 products carried by the most vendors changed when new vendors were added (KLOW replaced sermorelin), which changes the weight of a missing certificate under rule A1b. Lab evidence 2.9 to 3.0.

12. November 6, 2026GhostLabzFirst published at 6.14

    lab 7.3 / shipping 3.0 / pricing 8.5 / tenure 1.9 / transparency 3.0. First audit after the vendor's submission. All 34 catalogue products have a certificate confirmed at the issuing laboratory (ILS Laboratories), so the testing gate does not apply. Three site statements are contradicted by the certificates or the laboratory (rule A7 CLAIM, -0.3), and four certificates print a lot that differs from the laboratory's record (rule A7 LOT, -0.2).

13. November 6, 2026Hello StacksUp 6.08 → 6.14 (+0.06)

    Lab evidence recomputed under the published rule on 6 November 2026: the list of the 15 products carried by the most vendors changed when new vendors were added (KLOW replaced sermorelin), which changes the weight of a missing certificate under rule A1b. Lab evidence 5.8 to 5.9.

14. November 6, 2026Honest PeptideDown 7.52 → 7.42 (-0.10)

    Scores re-checked on 6 November 2026 after the correction review shipping and refunds 6.5 to 6.0.

15. November 6, 2026Honest PeptideDown 7.71 → 7.52 (-0.19)

    Corrections on 6 November 2026 after an independent review, each re-read on the live site. Returns: the 30-day returns wording is no longer on the site, and the policy puts right a problem with an order reported within 30 days, so the returns item moved from 3 to 1. Payment: checkout now offers a credit card gateway, so the payment item moved from 1 to 1.5. Shipping 8.0 to 6.5. Six products the store sells were added with certificates confirmed at Freedom Diagnostics, and semaglutide is scored from a new certificate of October 2026. Lab 8.1 to 8.3.

16. November 6, 2026Loti LabsDown 7.79 → 7.68 (-0.11)

    Three posted certificates print lots where the laboratory's copies of the same reports print none, with no dated correction (rule A7 LOT -0.2): lab 8.4 to 8.2.

17. November 6, 2026Lotus PeptideDown 3.74 → 3.68 (-0.06)

    Lab evidence recomputed under the published rule on 6 November 2026: the list of the 15 products carried by the most vendors changed when new vendors were added (KLOW replaced sermorelin), which changes the weight of a missing certificate under rule A1b. Lab evidence 1.6 to 1.5.

18. November 6, 2026Nextday PeptidesUp 3.21 → 3.27 (+0.06)

    Lab evidence recomputed under the published rule on 6 November 2026: the list of the 15 products carried by the most vendors changed when new vendors were added (KLOW replaced sermorelin), which changes the weight of a missing certificate under rule A1b. Lab evidence 3.0 to 3.1.

19. November 6, 2026NextSelf LabsFirst published at 6.26

    lab 7.1 / shipping 5.5 / pricing 6.9 / tenure 1.4 / transparency 3.0. First audit after the vendor's submission (reviewed 6 November 2026). 29 of 32 catalogue products have a certificate, all found at the issuing laboratory. LOT -0.2 and CLAIM -0.3. The ILS reports match reports issued to GhostLabz. Two GLP products are sold under code names (rule C9, -0.5 transparency).

20. November 6, 2026OMNI PeptidesDown 6.19 → 6.08 (-0.11)

    Lab evidence recomputed under the published rule on 6 November 2026: the list of the 15 products carried by the most vendors changed when new vendors were added (KLOW replaced sermorelin), which changes the weight of a missing certificate under rule A1b. Lab evidence 6.7 to 6.5.

21. November 6, 2026Onyx BiolabsUp 7.29 → 7.45 (+0.16)

    Lab evidence recomputed under the published rule on 6 November 2026: the list of the 15 products carried by the most vendors changed when new vendors were added (KLOW replaced sermorelin), which changes the weight of a missing certificate under rule A1b. Lab evidence 7.8 to 8.1.

22. November 6, 2026Peptide LabsUp 3.72 → 3.77 (+0.05)

    Lab score recomputed under the published rule on 6 November 2026: lab 1.9 to 2.0.

23. November 6, 2026Peptide ProsUp 3.56 → 3.62 (+0.06)

    Lab score recomputed under the published rule on 6 November 2026: lab 1.3 to 1.4.

24. November 6, 2026Peptide.ExpressDown 3.90 → 3.75 (-0.15)

    Corrections on 6 November 2026. The published rule gives lab 1.9, not 2.0. The FAQ says refunds are issued for verified damaged or incorrect shipments, while the shipping page offers a replacement or store credit and refunds only in exceptional circumstances, so the contradiction deduction applies. Shipping 7.0 to 6.5.

25. November 6, 2026Peptides SourceDown 7.33 → 7.17 (-0.16)

    Lab score recomputed under the published rule on 6 November 2026: lab 7.9 to 7.6.

26. November 6, 2026Peptix USAUp 8.11 → 8.16 (+0.05)

    Re-read on 6 November 2026: the home page's 7x testing wording is gone, so that claim adjustment is removed; the ISO 17025 wording remains (rule A7 CLAIM -0.2 to -0.1): lab 8.6 to 8.7.

27. November 6, 2026Pinnacle Peptide LabsDown 6.60 → 6.44 (-0.16)

    Lab evidence recomputed under the published rule on 6 November 2026: the SUPPLIER adjustment rose from 0.2 to 0.5 under rule A7 because 10 of its 11 Horizon certificates re-issue analyses first reported to another business, which is most of them. Lab evidence 7.0 to 6.7.

28. November 6, 2026Raw AminoUp 5.59 → 5.70 (+0.11)

    Lab score recomputed under the published rule on 6 November 2026: lab 5.5 to 5.7.

29. November 6, 2026S1ResearchUp 7.70 → 7.75 (+0.05)

    Lab score recomputed under the published rule on 6 November 2026: lab 8.6 to 8.7.

30. November 6, 2026Spartan PeptidesUp 3.32 → 3.38 (+0.06)

    Lab score recomputed under the published rule on 6 November 2026: lab 3.3 to 3.4.

31. November 6, 2026StudzPeptidesDown 7.10 → 6.99 (-0.11)

    Lab evidence recomputed under the published rule on 6 November 2026: a SUPPLIER adjustment of 0.2 was added under rule A7 because the 5-Amino-1MQ certificate re-issues an analysis first reported to PS SUPPLY, with the same dates, results and chromatogram on the laboratory's server; the match is disclosed on both reviews. Lab evidence 7.9 to 7.7.

32. November 6, 2026Thrive PeptidesDown 7.50 → 7.45 (-0.05)

    Landing pages claim ISO 17025 accredited testing by ILS Labs, while ILS Laboratories says there is no accreditation for its peptide testing (rule A7 CLAIM -0.1, reaching the -0.3 cap): lab 8.2 to 8.1.

33. November 6, 2026Vortex ResearchDown 5.55 → 5.50 (-0.05)

    Lab evidence recomputed under the published rule on 6 November 2026: the list of the 15 products carried by the most vendors changed when new vendors were added (KLOW replaced sermorelin), which changes the weight of a missing certificate under rule A1b. Lab evidence 5.1 to 5.0.

34. November 6, 2026Vortex ResearchDown 5.61 → 5.55 (-0.06)

    A home page tile claims an ISO 17025 lab, contradicted by the laboratories named on its reports (rule A7 CLAIM -0.1): lab 5.2 to 5.1.

35. November 6, 2026Vyal LabsUp 4.65 → 4.70 (+0.05)

    Lab evidence recomputed under the published rule on 6 November 2026: the list of the 15 products carried by the most vendors changed when new vendors were added (KLOW replaced sermorelin), which changes the weight of a missing certificate under rule A1b. Lab evidence 3.9 to 4.0.

36. November 6, 2026Vyal LabsUp 4.59 → 4.65 (+0.06)

    Lab score recomputed under the published rule on 6 November 2026: lab 3.8 to 3.9.

37. November 6, 2026YourFitnessPeptidesDown 2.80 → 2.75 (-0.05)

    Pricing re-checked on 6 November 2026 after the market medians were recalculated with GhostLabz and NextSelf Labs added pricing 8.1 to 7.8.

38. November 5, 2026CuroDown 6.33 → 6.27 (-0.06)

    Pricing re-checked on 5 November 2026 after the market medians were recalculated pricing 3.9 to 3.5.

39. November 5, 2026Direct PeptidesUp 7.30 → 7.43 (+0.13)

    Pricing re-checked on 5 November 2026 after the market medians were recalculated with Peptyes added pricing 4.9 to 5.8.

40. November 5, 2026Limitless BiotechUp 6.90 → 6.97 (+0.07)

    Pricing re-checked on 5 November 2026 after the market medians were recalculated with Peptyes added pricing 4.6 to 5.1.

41. November 5, 2026Limitless BiotechUp 6.84 → 6.90 (+0.06)

    Pricing re-checked on 5 November 2026 after the market medians were recalculated pricing 4.2 to 4.6.

42. November 5, 2026Peptide.ExpressDown 4.06 → 3.90 (-0.16)

    Full re-audit on 5 November 2026 after the company asked for an independent review. It has posted new Amino Metrics certificates for MOTS-c and tirzepatide, both confirmed at that laboratory, whose independence we could not establish. Our rules score the newest certificate for each product, so MOTS-c moved from a Freedom Diagnostics certificate to the flat score, and 1 of 21 products now has a certificate from a laboratory we could establish. Lab 2.3 to 2.0; operating history 1.6 to 1.7. Shipping, pricing and transparency are unchanged.

43. November 5, 2026PeptyesFirst published at 6.55

    lab 7.9 / shipping 4.5 / pricing 5.5 / tenure 3.6 / transparency 6.0. First audit after the vendor's submission (reviewed 5 November 2026). All 31 catalogue products have a certificate found at the issuing laboratory (30 Horizon Analytical, 1 Optiq Health Labs); every certificate names another business, Privilege Bio Labs, as the client (SUPPLIER -0.5), and the four Optiq reports carry no identity test although the site says every batch is tested for identity (CLAIM -0.1). Three GLP products are sold under code names (rule C9, -0.5 transparency).

44. November 5, 2026Rogue CompoundsUp 6.60 → 6.91 (+0.31)

    Re-audited on 5 November 2026 after the company reported site changes; each was checked on the live site and every certificate was re-confirmed at the issuing laboratory. The site no longer claims ISO 17025 accredited testing or identity by mass spectrometry, so the two site-claim adjustments no longer apply: lab 7.3 to 7.5. The terms now give the same 48-hour window as the refunds page for damaged or incorrect items, so the contradiction deduction no longer applies: shipping 6.5 to 7.0. The terms now name Wyoming law and a mailing address, which the state registry lists as a private mailbox: transparency 4.0 to 6.0. Product pages list the current batch, test date, laboratory and purity with a link to the laboratory's record. Certificates still cover 32 of the 36 products we score.

45. November 4, 2026Cernum BiosciencesDown 4.97 → 4.69 (-0.28)

    Lab evidence re-checked on 4 November 2026. The Janoshik reports tested on 3 November 2025 (GHK-Cu, MT-2, retatrutide and IGF-1 LR3) passed 12 months old and are the newest on record for those products, so under the published age rule (A6) each now carries the age deduction, alongside the older reports already past 12 months. Lab evidence 5.4 to 4.9.

46. November 4, 2026Honest PeptideUp 7.66 → 7.71 (+0.05)

    Lab evidence re-checked on 4 November 2026. The MT-2 certificate (Freedom Diagnostics, search code Hone2607090241, lot ML1005152026) returned not found at the laboratory on 22 October and now resolves there with the same lot, purity (99.74%) and net content as the vendor's copy, so it earns the confirmed-key points. Lab evidence 8.0 to 8.1.

47. November 3, 2026JD BioWorksDown 6.50 → 6.34 (-0.16)

    Certificates re-checked on 3 November 2026. The newest JD-2TR (tirzepatide) certificate the company posts is now a PuriLab Analytical report of 29 October 2026 for the 60 mg size, which resolves at PuriLab's own lookup. Under the published rule that the newest certificate per product counts (A6), tirzepatide is now scored from it, and because PuriLab's site names no operating company or street address it is not an established laboratory in our directory, so the certificate earns the minimum score. The earlier ILS certificates for the same product remain posted. Lab evidence 7.3 to 7.0.

48. November 3, 2026Lotus PeptideDown 3.85 → 3.74 (-0.11)

    Lab evidence re-checked on 3 November 2026. The company posted three certificates dated 30 October 2026 from Amino Metrics, a laboratory whose independence we could not establish, for tirzepatide, KPV and MOTS-c; all three were confirmed at that laboratory. Where a product has several certificates the newest is scored, so MOTS-c now rests on the Amino Metrics certificate, which scores a flat 2.0, instead of an earlier Freedom Diagnostics certificate. Lab 1.8 to 1.6.

49. November 3, 2026NextGen PepsDown 6.37 → 5.93 (-0.44)

    Lab evidence re-checked on 3 November 2026. No certificate newer than those of 25 September 2026 had been published, and the 14 bioregulator products still have none. Thirteen products on sale on the vendor's site that our catalogue had not listed were added: Epitalon and Kisspeptin-10 carry Bioviridian certificates confirmed at the laboratory, and eleven out-of-stock products have no certificate, which count under our coverage rule. Certificates now cover 33 of the 58 products we list. Lab 6.9 to 6.1.

50. November 3, 2026PepBioticsDown 2.28 → 2.23 (-0.05)

    Market medians updated on 3 November 2026 after the NextGen Peps re-check added priced listings: pricing 2.2 to 1.9.

51. November 3, 2026Peptide ProDown 5.69 → 5.63 (-0.06)

    Lab evidence re-checked on 3 November 2026. The sermorelin certificate (Freedom Diagnostics, reported 2 November 2025) passed 12 months old and is the newest one on record for that product, so under the published age rule (A6) it now counts as an older certificate. The certificate itself was re-confirmed at the laboratory. Lab evidence 6.1 to 6.0.

52. November 3, 2026Prime PeptidesDown 8.05 → 7.94 (-0.11)

    Market medians updated on 3 November 2026 after the Prime Peptides re-check added priced listings: pricing 7.0 to 6.3.

53. November 3, 2026Prime PeptidesDown 8.10 → 8.05 (-0.05)

    Lab evidence re-checked on 3 November 2026. Seven products the company sells were missing from our listings and now count under our coverage rule (the CJC-1295/ipamorelin blend, MOTS-c, NAD+, glutathione, melanotan I, KLOW and GLOW); each has a certificate confirmed at the issuing laboratory, but the KLOW and GLOW reports carry no purity figure and the only melanotan I report is more than 12 months old. Sermorelin and tirzepatide are now scored from their newest certificates. Lab 8.7 to 8.6.

54. November 2, 2026Ameano PeptidesUp 7.70 → 7.80 (+0.10)

    Ameano Peptides re-check of 2 November shipping and refunds 7.5 to 8.0.

55. November 2, 2026Amino ClubUp 8.03 → 8.08 (+0.05)

    Transparency re-checked on 2 November 2026 after an independent re-audit. The terms name Amino Club LLC as the operator, so the legal entity now counts; the phone number shown at our October check is no longer on the site. Transparency 5.0 to 6.0.

56. November 2, 2026Arctic Lab SupplyUp 6.16 → 7.09 (+0.93)

    Lab evidence re-checked on 2 November 2026 after the company published new reports. All 20 current reports on its report page were confirmed at the issuing laboratory (13 Freedom Diagnostics, 7 ILS Laboratories), adding certificates for MOTS-c, NAD+, ipamorelin, semax, semaglutide, tirzepatide, TB-500 and IGF-1 LR3. Nine products newly offered as pre-orders have no report yet and count as uncovered under our coverage rule, and where a product has several reports the newest is scored. Certificates now cover 16 of the 26 products we list, so the testing cap no longer applies. Lab 4.5 to 6.2.

57. November 2, 2026BioLongevity LabsDown 7.29 → 7.23 (-0.06)

    Market medians updated after the 2 November re-checks pricing 3.6 to 3.2.

58. November 2, 2026GenX BioUp 3.90 → 4.39 (+0.49)

    Catalogue re-checked on 2 November 2026 from the signed-in catalogue, read in the owner's browser: tirzepatide (GP-2 TRZ), a KLOW blend, NAD+ and SS-31 are on sale and in stock, so their Freedom Diagnostics certificates, confirmed at the laboratory, now count. Certificates cover 14 of the 37 products we list. The third-party testing cap still applies. Lab 2.0 to 2.9.

59. November 2, 2026GenX BioUp 3.68 → 3.90 (+0.22)

    Lab evidence re-checked on 2 November 2026 after the company published new reports. A Freedom Diagnostics certificate for retatrutide (GP-3 RT), with separate lots for each size, was confirmed at the laboratory, so certificates now cover 10 of the 33 products we list. Reports for tirzepatide, a KLOW blend, NAD+ and SS-31 were also confirmed at the laboratory but are not counted yet, because the catalog sits behind a login and we could not confirm those products are offered for sale. The third-party testing cap still applies. Lab 1.6 to 2.0.

60. November 2, 2026Hacker PeptidesDown 6.67 → 6.32 (-0.35)

    Shipping and transparency re-checked on 2 November 2026 after an independent re-audit. All sales are final and damaged or wrong items are reviewed case by case with no stated reship, replacement or refund, and the shipping policy gives a processing time of 1 to 3 business days, so both items score lower. A phone number is now shown on the contact page. Shipping 6.5 to 4.5, transparency 5.0 to 6.0.

61. November 2, 2026JD BioWorksDown 6.71 → 6.49 (-0.22)

    A Wolverine blend of BPC-157 and TB-500 was added to the catalogue in November 2026. Its certificate is from PuriLab Analytical, whose report resolves at its own lookup, but whose site names no operating company or street address, so it is not an established laboratory in our directory and the certificate earns the minimum score. Lab 7.7 to 7.3.

62. November 2, 2026NuScience PeptidesDown 6.49 → 6.43 (-0.06)

    Lab evidence re-checked on 2 November 2026. The melanotan II certificate (Freedom Diagnostics, reported 1 November 2025) passed 12 months old and is still the newest one the company posts for that product, so under the published age rule (A6) it now counts as an older certificate, alongside those for 5-amino-1MQ, IGF-1 LR3 and cagrilintide. The certificate itself was re-confirmed at the laboratory. Lab evidence 7.3 to 7.2.

63. November 2, 2026Pacific Edge LabsFirst published at 7.15

    lab 8.4 / shipping 6.0 / pricing 6.6 / tenure 1.8 / transparency 5.0. First audit after the vendor's submission (reviewed 2 November 2026). 34 of 35 catalogue products have a certificate; 33 are Freedom Diagnostics Testing reports found at the laboratory, each matching the copy the store posts. The Epithalon certificate (Vanguard Laboratory) could not be confirmed with the laboratory, and OT Acetate has no certificate. Three GLP products are sold under code names (rule C9, -0.5 transparency).

64. November 2, 2026Peptara LabsDown 2.66 → 2.38 (-0.28)

    Lab evidence re-checked on 2 November 2026 after our ranking review of 26 October. All 16 Titreon Analytical certificates for products the company sells opened at Titreon's new lookup with their printed keys. Titreon was added to our lab directory and graded as a laboratory whose independence is not established, so the certificates keep the flat 2.0. The Janoshik reports on the site are endotoxin screens, not identity or purity certificates. Fifteen products newly offered as pre-orders have no certificate yet and count under our coverage rule. Lab 1.7 to 1.2.

65. November 2, 2026PepVialDown 1.96 → 1.90 (-0.06)

    Market medians updated after Snowman Research was added pricing 6.2 to 5.8.

66. November 2, 2026Snowman ResearchFirst published at 3.05

    lab 0.0 / shipping 8.0 / pricing 8.8 / tenure 0.5 / transparency 2.0. First audit after the vendor's submission. No certificates of analysis are published, so each of the 15 catalogue products scores 0 for testing and the testing gate applies (0 of 15 confirmed); the gate's cap sits above the weighted score, so it does not lower it. Operating history is counted from the earliest dated customer review on the store, 27 October 2026.

67. November 2, 2026Spartan PeptidesDown 3.43 → 3.32 (-0.11)

    Lab evidence re-checked on 2 November 2026. The TB-500 certificate's ID, read from its QR code, was confirmed at MZ Biolabs, so all six published certificates are now confirmed at the laboratory. Epithalon and NAD+, both sold on the site without a published certificate, were added to the products we list, so certificates cover 6 of 17 products and the third-party testing cap still applies. Lab 3.5 to 3.3.

68. November 2, 2026Swiss ChemsDown 5.50 → 5.39 (-0.11)

    Lab evidence re-checked on 2 November 2026 after our ranking review of 26 October. The newest certificate for each product was confirmed at the issuing laboratory, adding Freedom Diagnostics Testing or Janoshik certificates for Melanotan II, Tesamorelin, DSIP, Glutathione, MK-677 and HCG. Sixteen products the store sells were missing from our list and now count under our coverage rule; seven of them have no certificate and three carry vendor documents that name no laboratory. Certificates confirmed at a laboratory cover 22 of 49 products, below the half needed to lift the testing cap. Lab 4.8 to 4.6.

69. November 2, 2026Welon Peptide SolutionsDown 2.29 → 2.13 (-0.16)

    Lab evidence re-checked on 2 November 2026. The store links the full Finnrick test history under each product, and under the published rule that the newest certificate per product counts (A6), the newest tests of retatrutide (17 July 2026, identity fail), BPC-157 (3 August 2026, fill 14% under label) and GHK-Cu (23 July 2026, fill 88% under label) now count in place of the earlier passing tests the store lists. Each reports a failed result, so each scores 0 (rule A4). Lab evidence 0.3 to 0.

70. November 2, 2026Welon Peptide SolutionsFirst published at 2.29

    lab 0.3 / shipping 2.0 / pricing 9.5 / tenure 0.5 / transparency 5.5. First audit after the vendor's submission. 5 of 59 catalogue products carry a certificate, all Finnrick test results issued to Finnrick rather than to the store (rule A7 SUPPLIER), with keys that could not be confirmed at the laboratories (rule A5), so testing could not be independently verified; the About and FAQ pages name a laboratory that does not match the reports (rule A7 CLAIM). No returns, lost-parcel or dispatch policy; crypto-only checkout. Every product is sold only in boxes of 10 vials; prices are compared per vial at the one-box price (rule E2). The store opened on 29 October 2026 (rule D).

71. November 1, 2026Bluum PeptidesFirst published at 7.48

    lab 8.3 / shipping 6.5 / pricing 7.7 / tenure 3.2 / transparency 6.0. First audit after the vendor's submission. 44 of 45 catalogue products have a certificate, and all 44 were found at the issuing laboratory (Freedom Diagnostics Testing 32, Horizon Analytical 12). The home page names laboratories and a purity level that the posted certificates do not bear out (rule A7 CLAIM, -0.2).

72. November 1, 2026Cernum BiosciencesDown 5.24 → 4.97 (-0.27)

    Lab score corrected on 1 November 2026: the stored sub-score read 5.9 while the uniform rule gives 5.4, because the three Janoshik reports tested on 31 October 2025 (BPC-157, CJC-1295, tesamorelin) passed 12 months on 31 October 2026 and each now carries the age deduction (rule A6), alongside the six reports from May 2025 already past 12 months; stored value corrected to the rule. Lab 5.9 to 5.4.

73. November 1, 2026Direct PeptidesDown 7.36 → 7.30 (-0.06)

    Market medians updated after Bluum Peptides was added pricing 5.3 to 4.9.

74. November 1, 2026PepVialUp 1.90 → 1.96 (+0.06)

    Market medians updated after Bluum Peptides was added pricing 5.8 to 6.2.

75. November 1, 2026Stack ResearchFirst published at 2.49

    lab 0.0 / shipping 7.5 / pricing 4.6 / tenure 0.5 / transparency 5.5. First audit after the vendor's submission. All 22 catalogue products have an Accumark Labs report whose key the laboratory confirms, but each posted copy prints a different client from the laboratory's own copy (rule A4), so every certificate scores 0 and none counts toward the testing gate; every report is issued to another business (rule A7 SUPPLIER, -0.5). No operating history before this audit could be established (rule D).

October 2026 478 changes, 331 minor

1. October 31, 2026Lotus PeptideUp 3.79 → 3.85 (+0.06)

   Lab score corrected on 31 October 2026: the stored sub-score read 1.7 while the publication note of 26 October and the uniform rule both give 1.8. Two Amino Metrics certificates (KPV 10mg, Tirzepatide 20mg) added to the listing on 31 October score the flat 2.0 for a laboratory whose independence is not established, and leave the rule value at 1.8. Lab 1.7 to 1.8.

2. October 31, 2026Redline Bio LabsUp 4.58 → 4.80 (+0.22)

   Lab score recalculated on 31 October 2026 under the uniform rule: five AV Analytics certificates issued on 27 October 2026 (Ipamorelin batch IPA-005, Oxytocin OXY-002, PT-141 PT-002, Sermorelin SER-005, TB-500 TB-006) were added to the listing from the vendor's lab-reports page, each earning 3 base points plus 2 for a laboratory in our directory, with no printed verification key and no purity figure; the laboratory lookup for AV Analytics remains unconfirmed on the vendor's own page. Lab 3.3 to 3.7.

3. October 30, 2026Peptides SourceDown 7.44 → 7.33 (-0.11)

   Lab score recalculated on 30 October 2026 under rule A6 (certificate age): the TB-500 and GLOW certificates, tested on 27 October 2025, became older than 12 months on 28 October 2026, and each certificate older than 12 months counts for a quarter less. Lab 8.1 to 7.9.

4. October 30, 2026Prime Peptide SolutionsUp 5.54 → 7.14 (+1.60)

   Re-check on 30 October 2026: on 28 October the vendor posted certificates for the ten products that had none (nine BT Labs reports tested on 26 October 2026 and an ILS certificate for NAD+). The ILS certificate was confirmed at the laboratory's portal; the BT Labs reports sit behind an identity form at the laboratory, so they count as key printed but not confirmed. Every one of the 20 products we list now has a certificate. Lab 4.4 to 7.3.

5. October 30, 2026Sports Technology LabsDown 6.99 → 6.88 (-0.11)

   Lab score recalculated on 30 October 2026 under rule A6 (certificate age): the PEG-MGF certificate, tested on 29 October 2025, became older than 12 months on 30 October 2026 and joins the four certificates tested on 17 October 2025 that already were; each certificate older than 12 months counts for a quarter less. Lab 6.8 to 6.6.

6. October 29, 2026Ageless PeptidesFirst published at 4.36

   lab 3.1 / shipping 6.5 / pricing 7.0 / tenure 0.5 / transparency 5.5. First audit after the vendor's submission. 9 of 20 catalogue products have a certificate, all from Vanguard Laboratory and all addressed to the vendor's supplier (rule A7 SUPPLIER, -0.5); none could be confirmed at the laboratory's lookup, so testing is not independently verified (cap 6.5, not reached). Two site claims about testing are not borne out by the certificates (rule A7 CLAIM, -0.2).

7. October 29, 2026AminoWave LabsFirst published at 5.85

   lab 6.6 / shipping 4.0 / pricing 8.4 / tenure 1.2 / transparency 2.0. First audit after the vendor's submission (reviewed 27 October 2026). 10 of 11 catalogue products have a certificate, all from Freedom Diagnostics Testing; nine were found at the laboratory, each identical to the laboratory's file. The Selank certificate was not found at the laboratory and itself reports a failed identity test, so it scores 0 under rule A4. Three site claims about testing are not borne out by the certificates (rule A7 CLAIM, -0.3).

8. October 29, 2026Arctic Lab SupplyUp 6.11 → 6.16 (+0.05)

   Market medians updated after Delix Labs and Ageless Peptides were added pricing 7.9 to 8.2.

9. October 29, 2026Delix LabsFirst published at 4.49

   lab 4.5 / shipping 5.5 / pricing 5.0 / tenure 1.3 / transparency 2.0. First audit after the vendor's submission. 14 of 24 catalogue products have a Janoshik report, and all 14 were found at the laboratory; none names Delix Labs as the client (rule A7 SUPPLIER, -0.5). Product pages show another product's test key, and the COA page lists a purity figure for three reports that give none (rule A7 CLAIM, -0.2).

10. October 29, 2026FRO PeptidesUp 6.61 → 6.67 (+0.06)

    Core products recomputed on 29 October 2026 (rule A1b): listings added for newly reviewed vendors made NAD+ a core product in place of CJC-1295, so a missing certificate for each now counts at its new weight: lab 7.2 to 7.3.

    Market medians updated after S1Research was added pricing 7.8 to 7.5.

21. October 27, 2026NovaForge LabsFirst published at 6.89

    lab 7.7 / shipping 5.0 / pricing 8.7 / tenure 0.9 / transparency 6.0. First audit after the vendor's submission. 13 of 14 catalogue products have a certificate, and every scored certificate was found at the issuing laboratory (Freedom Diagnostics Testing, ILS Laboratories). Vendor lot labels repeat across compounds (rule A7 LOT, -0.2), and the site's fentanyl-screen statement is not borne out by the Freedom certificates (rule A7 CLAIM, -0.1).

22. October 27, 2026Peptide LabsDown 3.71 → 3.66 (-0.05)

    Pricing recomputed on 27 October 2026: listings added for a newly reviewed vendor (Peptide Pro) moved the market median for the same products pricing 6.2 to 5.9.

23. October 27, 2026Peptide ProFirst published at 5.70

    lab 6.1 / shipping 5.5 / pricing 5.6 / tenure 3.1 / transparency 5.0. First audit after the vendor's submission, read through a signed-in account (rule F3). 42 of 43 catalogue products have a certificate and every scored certificate was found at the issuing laboratory (Bioviridian, Freedom Diagnostics Testing, Horizon Analytical). Nine posted copies differ from the laboratory's copy in their dates (rule A4, scored 0); a lot label repeats across compounds (A7 LOT, -0.2); ten Horizon reports repeat analyses first issued to another business (A7 SUPPLIER, -0.2); the home page purity statement is not borne out by two posted reports (A7 CLAIM, -0.1).

24. October 27, 2026S1ResearchFirst published at 7.70

    lab 8.6 / shipping 6.0 / pricing 9.5 / tenure 1.8 / transparency 5.0. First audit after the vendor's contact. 29 of 30 catalogue products have a certificate, and every scored certificate was found at the issuing laboratory (Freedom Diagnostics Testing, ILS Laboratories). Two product pages state a higher purity than their certificates (rule A7 CLAIM, -0.2).

25. October 26, 2026Lotus PeptideFirst published at 3.85

    lab 1.8 / shipping 6.5 / pricing 9.5 / tenure 1.1 / transparency 1.5. First audit after the vendor's submission. All 11 published certificates were found at the issuing laboratories and matched the store's copies, but they cover 4 of the 24 catalogue products it sells, so testing could not be independently verified for most of the range.

26. October 26, 2026Peptide LabsUp 3.66 → 3.71 (+0.05)

    Pricing recomputed on 26 October 2026: a vendor was removed from the directory, which moved the market median for the same products: pricing 5.9 to 6.2.

27. October 26, 2026Peptide Warehouse USDown 2.51 → 2.46 (-0.05)

    Pricing recomputed on 26 October 2026: listings added for a newly reviewed vendor (Lotus Peptide) moved the market median for the same products: pricing 8.5 to 8.2.

28. October 26, 2026StudzPeptidesFirst published at 7.10

    lab 7.9 / shipping 5.5 / pricing 9.5 / tenure 1.5 / transparency 3.0. First audit after the vendor's submission. 37 of 38 catalogue products have a certificate, and every scored certificate was found at the issuing laboratory (Freedom Diagnostics Testing, Vanguard Laboratory, ILS Laboratories, Kovera Labs). One lot label is printed on certificates for two different compounds (rule A7 LOT, -0.2).

29. October 25, 2026DAAVY ResearchUp 7.75 → 8.08 (+0.33)

    Certificate re-checked on 25 October 2026 (rule A4). DAAVY replaced its posted copy of Bioviridian COA9799 (5-Amino-1MQ 500 mg) with the laboratory's own copy: the two files are now identical, confirmed by two independent downloads, so the certificate scores on the full rubric again. Lab 7.9 to 8.5.

30. October 25, 2026Peptide Warehouse USFirst published at 2.51

    lab 0.0 / shipping 6.0 / pricing 8.5 / tenure 0.6 / transparency 0.0. First audit after the vendor's submission. The site published no certificates of analysis, so the lab score is 0 and testing could not be independently verified. Every product is sold only as a 10-vial pack; prices are compared per vial at the one-pack price (rule E2).

31. October 25, 2026Pexo LabsFirst published at 3.63

    lab 1.5 / shipping 6.0 / pricing 8.7 / tenure 0.9 / transparency 5.0. First audit after the vendor's submission. All fifteen certificates are on file with the issuing laboratory, Amino Metrics, but we could not establish that laboratory as an identifiable business, so its certificates count for the flat 2.0 and testing could not be independently verified; five of the 19 peptide products we list had no certificate.

32. October 25, 2026Vortex ResearchUp 5.56 → 5.67 (+0.11)

    Re-audited on 25 October 2026 after the vendor reported three site changes. The site now shows a Sheridan, Wyoming registered-agent address, which scores 1 of 2 for address (rule C3); no legal entity is named. The 99.5% purity badge is gone from the product pages, so that certificate-contradiction adjustment no longer applies. The returns policy, terms and product pages now give the same 7-day reporting window, but the free-shipping threshold still differs between pages, so one contradiction deduction stays. Lab 5.1 to 5.2, transparency 2.0 to 3.0, shipping unchanged at 6.5.

33. October 24, 2026Amino ClubUp 8.02 → 8.07 (+0.05)

    Certificates re-read on 24 October 2026 in the owner's signed-in browser: nine products moved to newer ILS Laboratories lots dated 22 October 2026, each confirmed at the laboratory's portal and identical to the laboratory's own copy. Certificates cover 38 of the 38 products we list. Lab 9.2 to 9.3.

34. October 24, 2026Bionova PeptidesUp 5.19 → 6.05 (+0.86)

    Pricing recomputed on 24 October 2026 after Bionova Peptides' first-review prices were recorded; other vendors move only through the market medians: pricing 2.4 to 8.1.

35. October 24, 2026Cernum BiosciencesDown 5.29 → 5.24 (-0.05)

    Pricing recomputed on 24 October 2026 after Bionova Peptides' first-review prices were recorded; other vendors move only through the market medians: pricing 5.3 to 5.0.

36. October 24, 2026DAAVY ResearchDown 8.08 → 7.75 (-0.33)

    Certificates re-checked on 24 October 2026 (rule A4). The 500 mg 5-Amino-1MQ certificate, Bioviridian COA9799, is the newest for the product, and the copy the vendor posts reads 507.11 mg and 99.78% while the laboratory's own copy of the same report reads 456.46 mg and 99.88%, so the product's certificate scores 0. If the vendor posts the laboratory's current copy, it scores on the full rubric again. Lab 8.5 to 7.9.

37. October 24, 2026Hacker PeptidesDown 7.33 → 6.67 (-0.66)

    Lab score recalculated on 24 October 2026 under rule A6 (certificate age): seven of the vendor's certificates, tested on 23 October 2025, became older than 12 months on 24 October 2026, and each certificate older than 12 months counts for a quarter less. Lab 7.7 to 6.5.

38. October 24, 2026LabFirst PeptidesUp 7.55 → 7.77 (+0.22)

    Thymosin Alpha-1 re-checked on 24 October 2026. Kovera Labs' own record for the lot now on sale, LF-65B-2609, reports a pass on every test, so the product is scored on that certificate. The failed result Kovera recorded for an earlier lot, LF-65A-2609, stays on record in the product's note. Lab 8.5 to 8.9.

39. October 24, 2026Nextday PeptidesUp 2.63 → 3.13 (+0.50)

    Three products added on 24 October 2026: MOTS-c, SS-31 and GLOW, sold on the vendor's site and covered by Freedom Diagnostics certificates confirmed at the laboratory. Their client field reads 'G', which the existing SUPPLIER adjustment already covers. Lab 2.0 to 2.9.

40. October 24, 2026Profound AminosDown 6.68 → 6.63 (-0.05)

    Pricing recomputed on 24 October 2026 after Bionova Peptides' first-review prices were recorded; other vendors move only through the market medians: pricing 7.4 to 7.1.

41. October 24, 2026Raw AminoDown 5.86 → 5.59 (-0.27)

    GHRP-6 certificate scored 0 under rule A4 (copy differs from the laboratory's copy): Raw Amino's posted copy of the MZ Biolabs certificate for lot Ts5aiN prints analysis date 6 July 2026, while the laboratory's own record of the same certificate gives 6 April 2026. Confirmed at MZ Biolabs on 22 October 2026 and twice on 24 October 2026; evidence preserved. Lab 6.0 to 5.5.

42. October 24, 2026Spartan PeptidesUp 2.94 → 3.43 (+0.49)

    Two products added on 24 October 2026: MOTS-c and the CJC-1295 no DAC / ipamorelin blend, both sold on the vendor's site and covered by MZ Biolabs certificates (lot PEP-04-26) confirmed at the laboratory. Lab 2.6 to 3.5.

43. October 24, 2026VoriLabsUp 6.75 → 6.91 (+0.16)

    Prices and certificates re-read on 24 October 2026 in the owner's signed-in browser, with each certificate checked again at the issuing laboratory. Retatrutide, tirzepatide, semaglutide and cagrilintide are now listed, each on a Freedom Diagnostics certificate confirmed at the laboratory; the KLOW certificate was replaced with a newer Freedom Diagnostics lot that includes endotoxin; PT-141 now carries its live price. Certificates cover 31 of the 31 products we list, 22 confirmed at the laboratory. Lab 7.2 to 7.5.

44. October 23, 2026AminoVaultUp 4.55 → 5.81 (+1.26)

    Certificate library re-checked on 23 October 2026: thirteen new certificates confirmed at the issuing laboratories. Lab 3.4 to 5.7; 14 of 22 products now have a certificate confirmed at the laboratory, so the vendor meets the third-party testing requirement and its score is no longer held by the testing-gate cap.

45. October 23, 2026AminoVaultUp 4.35 → 4.55 (+0.20)

    Prices re-checked on 23 October 2026 under rule E (standing prices only): prices taken from a time-limited sale were replaced with the vendor's standing price, current prices were re-read, and other vendors' price changes moved the market medians pricing 5.6 to 6.9.

46. October 23, 2026AnhydrolabsDown 2.76 → 2.69 (-0.07)

    Prices re-checked on 23 October 2026 under rule E (standing prices only): prices taken from a time-limited sale were replaced with the vendor's standing price, current prices were re-read, and other vendors' price changes moved the market medians pricing 9.5 to 9.0.

47. October 23, 2026Bionova PeptidesFirst published at 5.19

    lab 6.9 / shipping 4.5 / pricing 2.4 / tenure 1.7 / transparency 1.0. First audit after the vendor's submission. Sixteen of seventeen peptide certificates were confirmed with the issuing laboratory; three of the 19 peptide products we list had no certificate. Pricing uses the regular prices until the current sale has been live for 30 days.

48. October 23, 2026Core PeptidesUp 6.38 → 6.54 (+0.16)

    Certificate library re-checked on 23 October 2026: the GHK-Cu and Tesamorelin certificates were confirmed in Vanguard Laboratory's own records, so two more products count as confirmed at the issuing laboratory. Lab 6.0 to 6.3.

49. October 23, 2026DAAVY ResearchDown 8.22 → 8.08 (-0.14)

    Prices re-checked on 23 October 2026 under rule E (standing prices only): prices taken from a time-limited sale were replaced with the vendor's standing price, current prices were re-read, and other vendors' price changes moved the market medians pricing 9.3 to 8.4.

50. October 23, 2026Felix Chemical SupplyUp 7.47 → 7.53 (+0.06)

    Certificate library re-checked on 23 October 2026: seven new certificates confirmed at the issuing laboratories. Lab 8.7 to 8.8.

51. October 23, 2026GenX BioUp 3.33 → 3.66 (+0.33)

    Certificate library re-checked on 23 October 2026: two new certificates confirmed at the issuing laboratories. Lab 1.0 to 1.6.

52. October 23, 2026JD BioWorksDown 6.90 → 6.78 (-0.12)

    Prices re-checked on 23 October 2026 under rule E (standing prices only): prices taken from a time-limited sale were replaced with the vendor's standing price, current prices were re-read, and other vendors' price changes moved the market medians pricing 7.1 to 6.3.

53. October 23, 2026Oasis LabsUp 7.03 → 7.30 (+0.27)

    Certificate library re-checked on 23 October 2026: eleven new certificates confirmed at the issuing laboratories. Lab 7.8 to 8.3.

54. October 23, 2026Peptara LabsDown 2.77 → 2.72 (-0.05)

    Certificate library re-checked on 23 October 2026: the vendor no longer publishes a BPC-157 certificate (the product page states that no certificate is published, and the earlier file returns not found), so BPC-157 now counts as having no certificate; its separate Janoshik endotoxin report is kept on record as an add-on report. Lab 1.8 to 1.7.

55. October 23, 2026Peptide.ExpressUp 3.67 → 4.11 (+0.44)

    Certificate library re-checked on 23 October 2026: fifteen new certificates confirmed at the issuing laboratories. Lab 1.5 to 2.3.

56. October 23, 2026Redline Bio LabsUp 4.21 → 4.54 (+0.33)

    Lab score recalculated on 23 October 2026 after the vendor reported that its AV Analytics certificates had become searchable; 12 were confirmed at the laboratory on 23 October 2026. AV Analytics certificates now replace SteriGenix ones for KPV, KLOW, MOTS-c and Semax. The laboratory's record for a Cartalax batch, which the site does not post, reports that identity did not conform to the label claim, so Cartalax scores 0. Lab 2.6 to 3.2. 11 of 47 products now have a certificate confirmed at a directory laboratory, fewer than the half required, so the testing cap still applies; the cap sits above the weighted score, so it does not lower it.

57. October 23, 2026Rogue CompoundsFirst published at 6.61

    lab 7.3 / shipping 6.5 / pricing 6.5 / tenure 2.4 / transparency 4.0. First audit after the vendor's submission. Certificates cover 32 of the 36 products we list and every one matched the laboratory's own record; the lot-label and two site-claim adjustments apply.

58. October 23, 2026Southern AminosDown 8.14 → 8.09 (-0.05)

    Pricing recomputed on 23 October 2026 from current listings with the published rule (section E), after listings added or updated since 22 October, including a newly reviewed vendor's, moved the market median for the same products: pricing 8.8 to 8.5.

59. October 23, 2026Thrive PeptidesUp 7.34 → 7.50 (+0.16)

    Certificate library re-checked on 23 October 2026: three new certificates confirmed at the issuing laboratories. Lab 7.9 to 8.2.

60. October 23, 2026Vortex ResearchFirst published at 5.58

    lab 5.1 / shipping 6.5 / pricing 8.6 / tenure 1.6 / transparency 2.0. First audit after the vendor's submission. Ten of the fourteen certificates are partner-facility reports issued to another business, which count under the supplier adjustment; eleven of the 24 peptide products we list had no certificate.

61. October 23, 2026Zeptix LabsUp 7.89 → 8.17 (+0.28)

    Pricing recomputed on 23 October 2026 under the revised rule E1 (standing offers). Zeptix Labs' buy-one-get-one-free offer needs no code, has no end date and has been live since early September 2026, and a single vial costs the same as the pair, so the lowest total a buyer can pay for 8 sizes buys two vials and their price per mg counts both. Two more sizes on the offer count once they have been live 30 days. pricing 6.9 to 8.8.

62. October 23, 2026Zeptix LabsUp 7.00 → 7.90 (+0.90)

    Policies re-read on 23 October 2026 after the vendor reported changes, and confirmed on the live site that day: unopened returns within 30 days of delivery are refunded, lost and damaged parcels are reshipped free, and payment is by debit or credit card at checkout. shipping and refunds 5.5 to 10.0.

63. October 23, 2026Zeptix LabsUp 6.18 → 7.00 (+0.82)

    Certificate library re-read on 23 October 2026 at the vendor's request: 24 certificates were confirmed at the issuing laboratories. New certificates now cover ipamorelin, MT-2, the BPC-157 and TB-500 blend, and four newly listed products, and add endotoxin and sterility screens for BPC-157 and tirzepatide. Six of the new certificates are analyses first issued to another vendor, recorded under the published supplier adjustment. Lab 6.7 to 8.2.

64. October 22, 2026Ameano PeptidesDown 7.75 → 7.70 (-0.05)

    Claim deductions re-checked on 22 October 2026 under the published rule (only site claims contradicted by what the certificates show), each confirmed independently from primary sources. Lab 8.4 to 8.3. Note added 22 October 2026: a score on this entry was corrected from 7.69 to 7.70; it had been rounded down instead of half up.

65. October 22, 2026Ameano PeptidesDown 7.79 → 7.74 (-0.05)

    Re-scored on 22 October 2026 under the published rulebook, which now gives one rule for each judgement call and applies it to every vendor: transparency 7.0 to 6.0.

66. October 22, 2026Ameano PeptidesDown 8.66 → 7.79 (-0.87)

    Re-scored on 22 October 2026 under our published rubric for shipping, pricing, operating history and transparency, applied to every vendor the same day: prices re-read from the vendor's site and matched by milligrams per vial, operating history from the earliest dated evidence of the business, and policies scored item by item. shipping and refunds 10.0 to 7.5, pricing 9.5 to 7.9, operating history 2.8 to 2.6, transparency 9.5 to 7.0.

67. October 22, 2026Ameano PeptidesUp 7.83 → 8.66 (+0.83)

    Janoshik certificates confirmed on 22 October 2026 at the laboratory's own verification site, so each confirmed report now earns the key-confirmed credit under our published lab rule. Lab 6.9 to 8.4.

68. October 22, 2026Ameano PeptidesUp 7.78 → 7.83 (+0.05)

    Lab score recalculated on 22 October 2026 under the uniform published rubric applied to every vendor: every listed product was rescored on the same fixed certificate points, with fixed deductions for certificates more than 12 months old. Lab 6.8 to 6.9.

69. October 22, 2026Ameano PeptidesUp 7.29 → 7.78 (+0.49)

    Lab evidence re-checked on 20 October 2026 under our coverage rule, which counts a listed product with no published certificate as zero in the lab average. Certificates cover 28 of the 28 products we list that the vendor offers for sale. Lab 5.9 to 6.8.

70. October 22, 2026Amino AmigosDown 5.80 → 5.63 (-0.17)

    Laboratory rule change on 22 October 2026: tier C is now decided from the check results alone (L1 and L2 pass, L3 fails, and neither L4 nor L5 passes). Analiza Białek meets that test, so its three certificates for Amino Amigos no longer earn the laboratory points (rule A2). Lab 4.8 to 4.5.

71. October 22, 2026Amino AmigosUp 5.64 → 5.81 (+0.17)

    Laboratory directory completed on 22 October 2026: AV Analytics and Analiza Bialek were researched and added under the published lab criteria, so their certificates now receive the recognised-laboratory credit. Lab 4.5 to 4.8.

72. October 22, 2026Amino AmigosUp 5.30 → 5.64 (+0.34)

    Re-scored on 22 October 2026 under our published rubric for shipping, pricing, operating history and transparency, applied to every vendor the same day: prices re-read from the vendor's site and matched by milligrams per vial, operating history from the earliest dated evidence of the business, and policies scored item by item. shipping and refunds 6.0 to 7.5, pricing 8.0 to 8.5, operating history 4.5 to 4.4, transparency 4.0 to 3.5.

73. October 22, 2026Amino AmigosUp 4.97 → 5.30 (+0.33)

    Janoshik certificates confirmed on 22 October 2026 at the laboratory's own verification site, so each confirmed report now earns the key-confirmed credit under our published lab rule. Lab 3.9 to 4.5.

74. October 22, 2026Amino AmigosUp 4.25 → 4.97 (+0.72)

    Lab score recalculated on 22 October 2026 under the uniform published rubric applied to every vendor: every certificate shown is more than 12 months old and now takes the rubric's fixed 25 percent age reduction, which replaces an earlier halving; fixed deductions apply for certificates more than 12 months old. Lab 2.6 to 3.9.

75. October 22, 2026Amino AmigosDown 4.37 → 4.25 (-0.12)

    Lab evidence re-checked on 20 October 2026 under our coverage rule, which counts a listed product with no published certificate as zero in the lab average. Certificates cover 14 of the 14 products we list that the vendor offers for sale. Lab 2.8 to 2.6.

79. October 22, 2026Amino USAUp 6.84 → 7.56 (+0.72)

    Lab evidence re-checked on 20 October 2026 under our coverage rule, which counts a listed product with no published certificate as zero in the lab average. Certificates cover 19 of the 19 products we list that the vendor offers for sale. Lab 6.8 to 8.1.

80. October 22, 2026AminoVaultDown 4.53 → 4.37 (-0.16)

    Laboratory rule change on 22 October 2026: the accreditation point (+1) now applies only to a certificate tested on or after the date from which the accrediting body's register shows the accreditation as active. MDx BioAnalytical Laboratory's PJLA accreditation (certificate L26-502) is active from 9 June 2026, and nine of AminoVault's MDx certificates were tested before that date, so they no longer earn the point. Lab 3.7 to 3.4.

81. October 22, 2026AminoVaultUp 4.42 → 4.53 (+0.11)

    Lab score recalculated on 22 October 2026 under the published core-product rule (A1b): a missing certificate on one of the 15 most widely carried products still counts fully, while on any other product it now counts at half weight, so a broad catalogue is not penalised as much for its breadth. Lab 3.5 to 3.7.

82. October 22, 2026AminoVaultDown 4.48 → 4.42 (-0.06)

    Claim deductions re-checked on 22 October 2026 under the published rule (only site claims contradicted by what the certificates show), each confirmed independently from primary sources. Lab 3.6 to 3.5.

83. October 22, 2026AminoVaultDown 5.25 → 4.48 (-0.77)

    Re-scored on 22 October 2026 under version 2 of our published rules. The laboratories' own records for Selank, MT-2, SS-31, SLU-PP-332 and Sermorelin name a different client (Bulk Peptide Supply) from the copies AminoVault posts, so those five certificates now score 0 (a posted copy that differs from the laboratory's copy in product, quantity, purity, client or test dates scores 0); NAD+ was confirmed at the laboratory. The testing gate is now computed from the certificates, and 3 of 22 products have a certificate confirmed at a directory laboratory, fewer than the half required. Lab 5.0 to 3.6. Score 5.25 to 4.48.

84. October 22, 2026AminoVaultUp 4.97 → 5.25 (+0.28)

    MDx BioAnalytical Laboratory confirmed accredited in PJLA's register on 22 October 2026 (certificate L26-502, scope includes peptides and endotoxins), so its certificates now receive the accreditation credit under our published lab rule. Lab 4.5 to 5.0.

85. October 22, 2026AminoVaultDown 5.45 → 4.97 (-0.48)

    Re-scored on 22 October 2026 under our published rubric for shipping, pricing, operating history and transparency, applied to every vendor the same day: prices re-read from the vendor's site and matched by milligrams per vial, operating history from the earliest dated evidence of the business, and policies scored item by item. pricing 7.2 to 5.7, operating history 3.3 to 1.8, transparency 6.6 to 3.0.

86. October 22, 2026AminoVaultDown 5.95 → 5.45 (-0.50)

    Lab score recalculated on 22 October 2026 under the uniform published rubric applied to every vendor: every listed product was rescored on the same fixed certificate points, with fixed deductions for certificates more than 12 months old, one lot number printed on certificates for different compounds, site statements about testing that the certificates do not bear out and certificates ordered by a supplier or issued to another business. Lab 5.4 to 4.5.

    Re-scored on 22 October 2026 under our published rubric for shipping, pricing, operating history and transparency, applied to every vendor the same day: prices re-read from the vendor's site and matched by milligrams per vial, operating history from the earliest dated evidence of the business, and policies scored item by item. shipping and refunds 8.5 to 5.5, pricing 8.5 to 6.4, operating history 3.3 to 3.1, transparency 4.5 to 6.5.

91. October 22, 2026Apollo Peptide SciencesUp 6.50 → 7.49 (+0.99)

    Independent testing confirmed: the vendor's Janoshik certificates were opened at the laboratory's own verification site on 22 October 2026, so the untested cap no longer applies.

92. October 22, 2026Arctic Lab SupplyUp 5.97 → 6.19 (+0.22)

    Lab score recalculated on 22 October 2026 under the published core-product rule (A1b): a missing certificate on one of the 15 most widely carried products still counts fully, while on any other product it now counts at half weight, so a broad catalogue is not penalised as much for its breadth. Lab 4.1 to 4.5. Note added 22 October 2026: a score on this entry was corrected from 5.96 to 5.97; it had been rounded down instead of half up.

93. October 22, 2026Arctic Lab SupplyDown 6.10 → 5.93 (-0.17)

    Lab score recalculated on 22 October 2026 under the uniform published rubric applied to every vendor: ILS Laboratories, which issued certificates relied on here, does not publish ISO/IEC 17025 accreditation, so the accreditation point no longer applies. Lab 4.4 to 4.1. Note added 22 October 2026: PJLA's register lists ILS Laboratories' accreditation (certificate L25-631) as suspended from 22 October 2026; the accreditation point still does not apply (check L6).

    Lab score recalculated on 22 October 2026 under the uniform published rubric applied to every vendor: every listed product was rescored on the same fixed certificate points, with HCG scored on its February 2026 certificate. Lab 9.0 to 9.1.

96. October 22, 2026Azyrion LabsDown 5.58 → 5.47 (-0.11)

    Laboratory grades re-checked on 22 October 2026 under the published laboratory rulebook (checks L1 to L6 on How We Rate). ACS Laboratory's A2LA accreditation covers kratom, mushroom, cannabis and hemp testing but not peptides, so its certificates no longer earn the accreditation point (check L6); with under 12 months of peptide reports (check L5) it is graded A-. This affects six Azyrion Labs certificates. Lab 7.0 to 6.8.

97. October 22, 2026Azyrion LabsUp 5.53 → 5.58 (+0.05)

    Lab score recalculated on 22 October 2026 under the published core-product rule (A1b): a missing certificate on one of the 15 most widely carried products still counts fully, while on any other product it now counts at half weight, so a broad catalogue is not penalised as much for its breadth. Lab 6.9 to 7.0.

98. October 22, 2026Azyrion LabsUp 5.39 → 5.55 (+0.16)

    Re-scored on 22 October 2026 under version 2 of our published rules. The deduction for verification codes the laboratory could not find was retired: each such certificate now keeps its points for the printed key and earns none for confirmation, and codes on certificates we do not score no longer count. Lab 6.6 to 6.9. Score 5.39 to 5.55 (Weak to Fair).

99. October 22, 2026Azyrion LabsDown 5.46 → 5.39 (-0.07)

Note added 22 October 2026: a score on this entry was corrected from 5.38 to 5.39; it had been rounded down instead of half up.

100. October 22, 2026Azyrion LabsDown 5.68 → 5.46 (-0.22)

     Lab score recalculated on 22 October 2026 under the uniform published rubric applied to every vendor: the DSIP certificate listed on its product page is now counted; fixed deductions apply for verification codes the issuing laboratory could not find and one lot number printed on certificates for different compounds. Lab 7.0 to 6.6.

101. October 22, 2026Based ResearchDown 5.24 → 4.54 (-0.70)

     Re-scored on 22 October 2026 under our published rubric for shipping, pricing, operating history and transparency, applied to every vendor the same day: prices re-read from the vendor's site and matched by milligrams per vial, operating history from the earliest dated evidence of the business, and policies scored item by item. pricing 6.5 to 2.4, operating history 2.0 to 1.2, transparency 4.5 to 3.5.

102. October 22, 2026Based ResearchUp 5.07 → 5.24 (+0.17)

     Lab score recalculated on 22 October 2026 under the uniform published rubric applied to every vendor: an earlier method deduction that is not part of the published rubric was removed; fixed deductions apply for certificates ordered by a supplier or issued to another business. Lab 4.5 to 4.8.

103. October 22, 2026Based ResearchUp 4.52 → 5.07 (+0.55)

     Lab evidence re-checked on 20 October 2026 under our coverage rule, which counts a listed product with no published certificate as zero in the lab average. Certificates cover 41 of the 41 products we list that the vendor offers for sale. Lab 3.5 to 4.5.

104. October 22, 2026BioInfinityDown 3.86 → 3.71 (-0.15)

     Re-scored on 22 October 2026 under the published rulebook, which now gives one rule for each judgement call and applies it to every vendor: shipping and refunds 8.5 to 7.5, transparency 5.0 to 6.0.

105. October 22, 2026BioInfinityDown 4.44 → 3.86 (-0.58)

     Re-scored on 22 October 2026 under our published rubric for shipping, pricing, operating history and transparency, applied to every vendor the same day: prices re-read from the vendor's site and matched by milligrams per vial, operating history from the earliest dated evidence of the business, and policies scored item by item. shipping and refunds 9.5 to 8.5, pricing 7.2 to 5.4, transparency 7.1 to 5.0.

106. October 22, 2026BioInfinityDown 4.54 → 4.44 (-0.10)

     Lab score recalculated on 22 October 2026 under the uniform published rubric applied to every vendor: the DSIP and CJC-1295/Ipamorelin records now linked from the product pages are counted; every certificate comes from Verum Analytics, which we could not establish as an independent laboratory, so each scores the fixed 2.0; fixed deductions apply for one lot number printed on certificates for different compounds. Lab 2.0 to 1.8.

107. October 22, 2026BioInfinityDown 7.31 → 4.54 (-2.77)

     Lab evidence and pricing re-checked on 22 October 2026. The certificate records come from verumlab.ch, which we could not establish as an independent laboratory (domain registered after most of its reported analysis dates; every record is for BioInfinity Lab and is built into the site's own code), so lab moves from 6.4 to 2.0 and the third-party testing cap applies. Pricing moves from 9.5 to 7.2 on a fresh comparison with the market median.

108. October 22, 2026BioLongevity LabsDown 7.54 → 7.32 (-0.22)

     Laboratory rule change on 22 October 2026: the accreditation point (+1) now applies only to a certificate tested on or after the date from which the accrediting body's register shows the accreditation as active. MDx BioAnalytical Laboratory's PJLA accreditation (certificate L26-502) is active from 9 June 2026, and 15 of BioLongevity Labs' MDx certificates were tested before that date, so they no longer earn the point. Lab 8.5 to 8.1.

109. October 22, 2026BioLongevity LabsUp 7.37 → 7.54 (+0.17)

     BioRegen certificates confirmed at the laboratory's own lookup on 22 October 2026 (an invented test key returned no match), so they now receive the confirmed-key credit under our published lab rule. Lab 8.2 to 8.5.

110. October 22, 2026BioLongevity LabsDown 7.57 → 7.37 (-0.20)

     Re-scored on 22 October 2026 under the published rulebook, which now gives one rule for each judgement call and applies it to every vendor: shipping and refunds 8.5 to 7.5.

111. October 22, 2026BioLongevity LabsUp 7.40 → 7.57 (+0.17)

     Re-scored on 22 October 2026 under version 2 of our published rules. The deduction for verification codes the laboratory could not find was retired: each such certificate now keeps its points for the printed key and earns none for confirmation, and codes on certificates we do not score no longer count. The testing gate is now computed from the certificates: 16 of 35 products have a certificate confirmed at a directory laboratory, fewer than the half required, so the cap applies; it sits above the weighted score, so it does not lower it. Lab 7.9 to 8.2. Score 7.40 to 7.57.

112. October 22, 2026BioLongevity LabsUp 7.07 → 7.40 (+0.33)

     MDx BioAnalytical Laboratory confirmed accredited in PJLA's register on 22 October 2026 (certificate L26-502, scope includes peptides and endotoxins), so its certificates now receive the accreditation credit under our published lab rule. Lab 7.3 to 7.9.

113. October 22, 2026BioLongevity LabsUp 6.96 → 7.07 (+0.11)

     Laboratory directory completed on 22 October 2026: AV Analytics and Analiza Bialek were researched and added under the published lab criteria, so their certificates now receive the recognised-laboratory credit. Lab 7.1 to 7.3.

     Lab score recalculated on 22 October 2026 under the uniform published rubric applied to every vendor: every listed product was rescored on the same fixed certificate points, with fixed deductions for certificates more than 12 months old, site statements about testing that the certificates do not bear out and verification codes the issuing laboratory could not find. Lab 7.4 to 7.1.

116. October 22, 2026Biotech PeptidesDown 5.95 → 5.79 (-0.16)

     MZ Biolabs' own record for the HGH Fragment 176-191 certificate (lot 3140029, analysed 26 July 2026) reports that identity failed: the laboratory found AOD-9604 and did not detect HGH Fragment 176-191. The copy on the vendor's site shows 98.01% purity without that result. Confirmed independently twice from the laboratory's record; the certificate now scores 0 (rule A4). Lab 5.6 to 5.3.

117. October 22, 2026Biotech PeptidesUp 5.78 → 5.95 (+0.17)

     Lab score recalculated on 22 October 2026 under the published core-product rule (A1b): a missing certificate on one of the 15 most widely carried products still counts fully, while on any other product it now counts at half weight, so a broad catalogue is not penalised as much for its breadth. Lab 5.3 to 5.6.

118. October 22, 2026Biotech PeptidesDown 5.84 → 5.78 (-0.06)

     Claim deductions re-checked on 22 October 2026 under the published rule (only site claims contradicted by what the certificates show), each confirmed independently from primary sources. Lab 5.4 to 5.3.

121. October 22, 2026BulkGLPUp 6.57 → 6.80 (+0.23)

     Lab score recalculated on 22 October 2026 under the published core-product rule (A1b): a missing certificate on one of the 15 most widely carried products still counts fully, while on any other product it now counts at half weight, so a broad catalogue is not penalised as much for its breadth. Lab 7.5 to 7.9. Note added 22 October 2026: a score on this entry was corrected from 6.79 to 6.80; it had been rounded down instead of half up.

122. October 22, 2026BulkGLPDown 6.74 → 6.57 (-0.17)

     Claim deductions re-checked on 22 October 2026 under the published rule (only site claims contradicted by what the certificates show), each confirmed independently from primary sources. Lab 7.8 to 7.5.

123. October 22, 2026BulkGLPDown 8.21 → 6.72 (-1.49)

     Re-scored on 22 October 2026 under our published rubric for shipping, pricing, operating history and transparency, applied to every vendor the same day: prices re-read from the vendor's site and matched by milligrams per vial, operating history from the earliest dated evidence of the business, and policies scored item by item. shipping and refunds 9.5 to 6.5, pricing 9.5 to 5.3, operating history 3.3 to 2.2, transparency 8.5 to 4.5.

124. October 22, 2026BulkGLPUp 7.44 → 8.21 (+0.77)

125. October 22, 2026Cernum BiosciencesUp 5.07 → 5.25 (+0.18)

     Re-scored on 22 October 2026 under the published rulebook, which now gives one rule for each judgement call and applies it to every vendor: shipping and refunds 4.5 to 5.5, transparency 1.5 to 1.0.

126. October 22, 2026Cernum BiosciencesDown 5.25 → 5.07 (-0.18)

     Re-scored on 22 October 2026 under our published rubric for shipping, pricing, operating history and transparency, applied to every vendor the same day: prices re-read from the vendor's site and matched by milligrams per vial, operating history from the earliest dated evidence of the business, and policies scored item by item. shipping and refunds 3.3 to 4.5, pricing 7.6 to 5.1, operating history 2.0 to 1.7, transparency 2.0 to 1.5.

128. October 22, 2026Cernum BiosciencesUp 4.31 → 4.58 (+0.27)

     Lab score recalculated on 22 October 2026 under the uniform published rubric applied to every vendor: the Janoshik reports linked for 13 of the 14 products we list are now scored as laboratory reports rather than vendor sheets, including the GHK-Cu and PT-141 reports, while Semax shows only a vendor-issued sheet; fixed deductions apply for certificates more than 12 months old, certificates ordered by a supplier or issued to another business, site statements about testing that the certificates do not bear out and one lot number printed on certificates for different compounds. Lab 4.2 to 4.7.

129. October 22, 2026Cernum BiosciencesUp 3.65 → 4.31 (+0.66)

     Lab evidence re-checked on 20 October 2026 under our coverage rule, which counts a listed product with no published certificate as zero in the lab average. Certificates cover 13 of the 14 products we list that the vendor offers for sale. Lab 3.0 to 4.2.

130. October 22, 2026Core PeptidesDown 6.82 → 6.38 (-0.44)

     Laboratory grades re-checked on 22 October 2026 under the published laboratory rulebook (checks L1 to L6 on How We Rate). Vanguard Laboratory's A2LA accreditation does not cover peptide testing (its scope lists microbiology, trace elements, preservatives and residual solvents), so its certificates no longer earn the accreditation point (check L6); its identity test is by HPLC retention time (check L4), which grades it B+. This affects 13 of Core Peptides' certificates. Lab 6.8 to 6.0.

131. October 22, 2026Core PeptidesUp 6.71 → 6.82 (+0.11)

     Lab score recalculated on 22 October 2026 under the published core-product rule (A1b): a missing certificate on one of the 15 most widely carried products still counts fully, while on any other product it now counts at half weight, so a broad catalogue is not penalised as much for its breadth. Lab 6.6 to 6.8. Note added 22 October 2026: a score on this entry was corrected from 6.70 to 6.71; it had been rounded down instead of half up. Note added 22 October 2026: a score on this entry was corrected from 6.81 to 6.82; it had been rounded down instead of half up.

132. October 22, 2026Core PeptidesUp 6.63 → 6.68 (+0.05)

     Claim deductions re-checked on 22 October 2026 under the published rule that a claim deduction applies only where a site claim is contradicted by what its certificates show, never for products merely lacking a certificate. Lab 6.5 to 6.6.

133. October 22, 2026Core PeptidesUp 6.61 → 6.67 (+0.06)

     Lab score recalculated on 22 October 2026 under the uniform published rubric applied to every vendor: every listed product was rescored on the same fixed certificate points, with fixed deductions for site statements about testing that the certificates do not bear out. Lab 6.4 to 6.5.

134. October 22, 2026CuroUp 6.28 → 6.40 (+0.12)

     Re-scored on 22 October 2026 under our published rubric for shipping, pricing, operating history and transparency, applied to every vendor the same day: prices re-read from the vendor's site and matched by milligrams per vial, operating history from the earliest dated evidence of the business, and policies scored item by item. shipping and refunds 6.0 to 7.5, pricing 5.5 to 4.4, operating history 2.5 to 1.3, transparency 5.5 to 6.5.

135. October 22, 2026CuroUp 6.17 → 6.28 (+0.11)

     Lab score recalculated on 22 October 2026 under the uniform published rubric applied to every vendor: an earlier document-quality deduction that is not part of the published rubric was removed. Lab 6.8 to 7.0.

136. October 22, 2026DAAVY ResearchUp 8.13 → 8.24 (+0.11)

     Lab deductions independently re-verified on 22 October 2026: the 5-Amino-1MQ certificate the vendor shows is an earlier version issued by the laboratory, not an altered copy, so that deduction was removed. Lab 8.3 to 8.5.

137. October 22, 2026DAAVY ResearchUp 7.73 → 8.13 (+0.40)

     Re-scored on 22 October 2026 under our published rubric for shipping, pricing, operating history and transparency, applied to every vendor the same day: prices re-read from the vendor's site and matched by milligrams per vial, operating history from the earliest dated evidence of the business, and policies scored item by item. shipping and refunds 8.0 to 9.5, pricing 8.7 to 9.3, operating history 0.6 to 0.9.

138. October 22, 2026DAAVY ResearchUp 7.01 → 7.73 (+0.72)

     Lab score recalculated on 22 October 2026 under the uniform published rubric applied to every vendor: earlier judgement deductions that are not part of the published rubric were removed; fixed deductions apply for posted certificate copies that differ from the laboratory's own copy. Lab 7.0 to 8.3. Note added 22 October 2026: later that day this deduction was replaced by rule A4, under which such a certificate scores 0.

139. October 22, 2026Direct PeptidesDown 7.61 → 7.39 (-0.22)

     Re-scored on 22 October 2026 under the published rulebook, which now gives one rule for each judgement call and applies it to every vendor: shipping and refunds 9.5 to 8.5, transparency 4.5 to 4.0.

140. October 22, 2026Direct PeptidesUp 7.50 → 7.61 (+0.11)

     Re-scored on 22 October 2026 under version 2 of our published rules. The deduction for verification codes the laboratory could not find was retired: each such certificate now keeps its points for the printed key and earns none for confirmation, and codes on certificates we do not score no longer count. The posted oxytocin certificate prints 9.96 mg where the laboratory's copy prints 4.96 mg, so it now scores 0 instead of carrying a separate deduction. Lab 8.0 to 8.2. Score 7.50 to 7.61.

141. October 22, 2026Direct PeptidesDown 7.61 → 7.50 (-0.11)

     Lab score recalculated on 22 October 2026 under the uniform published rubric applied to every vendor: every listed product was rescored on the same fixed certificate points, with fixed deductions for posted certificate copies that differ from the laboratory's own copy and verification codes the issuing laboratory could not find. Lab 8.2 to 8.0.

143. October 22, 2026Direct PeptidesUp 7.50 → 7.72 (+0.22)

     Lab evidence re-checked on 20 October 2026 under our coverage rule, which counts a listed product with no published certificate as zero in the lab average. Certificates cover 33 of the 33 products we list that the vendor offers for sale. Lab 7.8 to 8.2.

144. October 22, 2026Drexa LabsUp 3.11 → 3.33 (+0.22)

     Lab score recalculated on 22 October 2026 under the published core-product rule (A1b): a missing certificate on one of the 15 most widely carried products still counts fully, while on any other product it now counts at half weight, so a broad catalogue is not penalised as much for its breadth. Lab 0.9 to 1.3. Note added 22 October 2026: a score on this entry was corrected from 3.10 to 3.11; it had been rounded down instead of half up.

146. October 22, 2026Drexa LabsDown 4.09 → 3.98 (-0.11)

     Lab score recalculated on 22 October 2026 under the uniform published rubric applied to every vendor: ILS Laboratories, which issued certificates relied on here, does not publish ISO/IEC 17025 accreditation, so the accreditation point no longer applies; fixed deductions apply for one lot number printed on certificates for different compounds. Lab 1.1 to 0.9. Note added 22 October 2026: PJLA's register lists ILS Laboratories' accreditation (certificate L25-631) as suspended from 22 October 2026; the accreditation point still does not apply (check L6).

147. October 22, 2026Felix Chemical SupplyUp 7.31 → 7.47 (+0.16)

     Re-scored on 22 October 2026 under version 2 of our published rules. The deduction for verification codes the laboratory could not find was retired: each such certificate now keeps its points for the printed key and earns none for confirmation, and codes on certificates we do not score no longer count: the 36 codes behind it are all on certificates that are not the scored certificate for any product we list (every scored Felix certificate is confirmed at the laboratory). Lab 8.4 to 8.7. Score 7.31 to 7.47.

148. October 22, 2026Felix Chemical SupplyUp 7.08 → 7.31 (+0.23)

     Full certificate library checked on 22 October 2026: 420 of 456 certificate codes resolve at the issuing laboratories and 418 match the lab's own copy; 36 codes were not found at the lab, a fixed deduction under our published lab rule. Lab 8.0 to 8.4.

     Laboratory grades re-checked on 22 October 2026 under the published laboratory rulebook (checks L1 to L6 on How We Rate). Vanguard Laboratory's A2LA accreditation does not cover peptide testing (its scope lists microbiology, trace elements, preservatives and residual solvents), so its certificates no longer earn the accreditation point (check L6); its identity test is by HPLC retention time (check L4), which grades it B+. This affects all 21 Hello Stacks certificates. The same check found that these certificates carry no identity test, so our records no longer list LC-MS identity for them. Lab 6.4 to 5.7.

     Re-scored on 22 October 2026 under our published rubric for shipping, pricing, operating history and transparency, applied to every vendor the same day: prices re-read from the vendor's site and matched by milligrams per vial, operating history from the earliest dated evidence of the business, and policies scored item by item. shipping and refunds 8.0 to 6.5, pricing 8.0 to 6.7, operating history 1.0 to 0.7, transparency 8.0 to 7.0. Note added 22 October 2026: a score on this entry was corrected from 7.47 to 7.48; it had been rounded down instead of half up.

178. October 22, 2026LabFirst PeptidesUp 7.54 → 8.04 (+0.50)

     Lab score recalculated on 22 October 2026 under the uniform published rubric applied to every vendor: earlier judgement deductions that are not part of the published rubric were removed; fixed deductions apply for posted certificate copies that differ from the laboratory's own copy. Lab 7.8 to 8.7. Note added 22 October 2026: later that day this deduction was replaced by rule A4, under which such a certificate scores 0.

179. October 22, 2026Limitless BiotechUp 6.41 → 6.85 (+0.44)

     Lab score recalculated on 22 October 2026 under the published core-product rule (A1b): a missing certificate on one of the 15 most widely carried products still counts fully, while on any other product it now counts at half weight, so a broad catalogue is not penalised as much for its breadth. Lab 6.7 to 7.5.

180. October 22, 2026Limitless BiotechUp 6.31 → 6.41 (+0.10)

     Re-scored on 22 October 2026 under the published rulebook, which now gives one rule for each judgement call and applies it to every vendor: shipping and refunds 6.5 to 7.0.

181. October 22, 2026Limitless BiotechDown 7.34 → 6.31 (-1.03)

     Re-scored on 22 October 2026 under our published rubric for shipping, pricing, operating history and transparency, applied to every vendor the same day: prices re-read from the vendor's site and matched by milligrams per vial, operating history from the earliest dated evidence of the business, and policies scored item by item. shipping and refunds 9.0 to 6.5, pricing 7.2 to 4.3, operating history 6.5 to 9.1, transparency 9.0 to 4.5.

182. October 22, 2026Limitless BiotechUp 7.29 → 7.34 (+0.05)

     Lab score recalculated on 22 October 2026 under the uniform published rubric applied to every vendor: every listed product was rescored on the same fixed certificate points, with fixed deductions for site statements about testing that the certificates do not bear out. Lab 6.6 to 6.7.

     Lab score recalculated on 22 October 2026 under the uniform published rubric applied to every vendor: earlier judgement deductions that are not part of the published rubric were removed; fixed deductions apply for posted certificate copies that differ from the laboratory's own copy. Lab 7.3 to 8.4. Note added 22 October 2026: later that day this deduction was replaced by rule A4, under which such a certificate scores 0.

     Re-scored on 22 October 2026 under our published rubric for shipping, pricing, operating history and transparency, applied to every vendor the same day: prices re-read from the vendor's site and matched by milligrams per vial, operating history from the earliest dated evidence of the business, and policies scored item by item. shipping and refunds 8.0 to 4.5, pricing 6.5 to 4.7, operating history 2.0 to 1.3, transparency 2.5 to 0.0.

189. October 22, 2026Modern AminosDown 7.98 → 7.92 (-0.06)

     Laboratory grades re-checked on 22 October 2026 under the published laboratory rulebook (checks L1 to L6 on How We Rate). Vanguard Laboratory's A2LA accreditation does not cover peptide testing (its scope lists microbiology, trace elements, preservatives and residual solvents), so its certificates no longer earn the accreditation point (check L6); its identity test is by HPLC retention time (check L4), which grades it B+. This affects one Modern Aminos certificate (dihexa). Lab 8.8 to 8.7.

190. October 22, 2026Modern AminosUp 7.87 → 7.98 (+0.11)

     Lab score recalculated on 22 October 2026 under the published core-product rule (A1b): a missing certificate on one of the 15 most widely carried products still counts fully, while on any other product it now counts at half weight, so a broad catalogue is not penalised as much for its breadth. Lab 8.6 to 8.8.

191. October 22, 2026Modern AminosDown 7.92 → 7.87 (-0.05)

     Claim deductions re-checked on 22 October 2026 under the published rule (only site claims contradicted by what the certificates show), each confirmed independently from primary sources. Lab 8.7 to 8.6.

192. October 22, 2026Modern AminosUp 7.75 → 7.91 (+0.16)

     Re-scored on 22 October 2026 under version 2 of our published rules. The deduction for verification codes the laboratory could not find was retired: each such certificate now keeps its points for the printed key and earns none for confirmation, and codes on certificates we do not score no longer count; the deduction for a posted copy with a one-character lot-label typo was also retired, because a lot-label typo is not a material difference. Lab 8.4 to 8.7. Score 7.75 to 7.91.

193. October 22, 2026Modern AminosUp 7.64 → 7.75 (+0.11)

     Lab deductions independently re-verified from primary sources on 22 October 2026; a deduction that could not be confirmed was removed or reduced. Lab 8.2 to 8.4.

194. October 22, 2026Modern AminosDown 8.47 → 7.64 (-0.83)

     Re-scored on 22 October 2026 under our published rubric for shipping, pricing, operating history and transparency, applied to every vendor the same day: prices re-read from the vendor's site and matched by milligrams per vial, operating history from the earliest dated evidence of the business, and policies scored item by item. shipping and refunds 10.0 to 7.0, pricing 7.9 to 8.1, operating history 5.5 to 4.7, transparency 10.0 to 5.5.

195. October 22, 2026Modern AminosDown 8.64 → 8.47 (-0.17)

     Lab score recalculated on 22 October 2026 under the uniform published rubric applied to every vendor: every listed product was rescored on the same fixed certificate points, with fixed deductions for verification codes the issuing laboratory could not find, posted certificate copies that differ from the laboratory's own copy and certificates ordered by a supplier or issued to another business. Lab 8.5 to 8.2.

196. October 22, 2026Modern AminosUp 7.98 → 8.64 (+0.66)

     Lab evidence re-checked on 20 October 2026 under our coverage rule, which counts a listed product with no published certificate as zero in the lab average. Certificates cover 33 of the 34 products we list that the vendor offers for sale. Lab 7.3 to 8.5.

197. October 22, 2026Modified AminosUp 6.64 → 6.75 (+0.11)

     Re-scored on 22 October 2026 under version 2 of our published rules. The Ethos sample IDs printed on 16 certificates now count as printed keys, and the current Epitalon, MOTS-c and GLOW certificates were confirmed at Ethos; the Ethos microbiological screen (USP <61>/<62>) is microbial limits, not sterility, so it no longer earns sterility points. The testing gate is now computed from the certificates: 3 of 25 products have a certificate confirmed at a directory laboratory (Ethos lists only what a client chooses to publish, and Vanguard's lookup could not be reached), fewer than the half required, so the cap now applies and holds the score at its cap. Lab 5.4 to 6.6. Score 6.64 to 6.75.

198. October 22, 2026Modified AminosUp 6.50 → 6.64 (+0.14)

     Re-scored on 22 October 2026 under our published rubric for shipping, pricing, operating history and transparency, applied to every vendor the same day: prices re-read from the vendor's site and matched by milligrams per vial, operating history from the earliest dated evidence of the business, and policies scored item by item. shipping and refunds 9.0 to 9.5, pricing 9.0 to 9.2, operating history 2.0 to 1.8, transparency 5.5 to 6.0.

199. October 22, 2026Modified AminosUp 6.44 → 6.50 (+0.06)

     Lab score recalculated on 22 October 2026 under the uniform published rubric applied to every vendor: every listed product was rescored on the same fixed certificate points. Lab 5.3 to 5.4.

200. October 22, 2026Nextday PeptidesDown 2.69 → 2.63 (-0.06)

     Laboratory grades re-checked on 22 October 2026 under the published laboratory rulebook (checks L1 to L6 on How We Rate). Harrens Lab's A2LA accreditation covers cannabis, hemp and food microbiology testing but not peptides, so its certificate no longer earns the accreditation point (check L6); it also offers no public way to look up a report (check L3), which grades it B-. This affects one Nextday Peptides certificate (BPC-157). Lab 2.1 to 2.0.

201. October 22, 2026Nextday PeptidesUp 2.36 → 2.69 (+0.33)

     Lab score recalculated on 22 October 2026 under the published core-product rule (A1b): a missing certificate on one of the 15 most widely carried products still counts fully, while on any other product it now counts at half weight, so a broad catalogue is not penalised as much for its breadth. Lab 1.5 to 2.1.

202. October 22, 2026Nextday PeptidesUp 2.30 → 2.36 (+0.06)

     Claim deductions re-checked on 22 October 2026 under the published rule that a claim deduction applies only where a site claim is contradicted by what its certificates show, never for products merely lacking a certificate. Lab 1.4 to 1.5.

203. October 22, 2026Nextday PeptidesDown 2.50 → 2.30 (-0.20)

     Re-scored on 22 October 2026 under the published rulebook, which now gives one rule for each judgement call and applies it to every vendor: shipping and refunds 4.5 to 3.5.

204. October 22, 2026Nextday PeptidesUp 2.45 → 2.50 (+0.05)

     MDx BioAnalytical Laboratory confirmed accredited in PJLA's register on 22 October 2026 (certificate L26-502, scope includes peptides and endotoxins), so its certificates now receive the accreditation credit under our published lab rule. Lab 1.3 to 1.4.

205. October 22, 2026Nextday PeptidesDown 4.16 → 2.45 (-1.71)

     Re-scored on 22 October 2026 under our published rubric for shipping, pricing, operating history and transparency, applied to every vendor the same day: prices re-read from the vendor's site and matched by milligrams per vial, operating history from the earliest dated evidence of the business, and policies scored item by item. shipping and refunds 9.5 to 4.5, pricing 7.2 to 3.4, operating history 2.0 to 1.9, transparency 7.3 to 4.5.

     Lab score recalculated on 22 October 2026 under the published core-product rule (A1b): a missing certificate on one of the 15 most widely carried products still counts fully, while on any other product it now counts at half weight, so a broad catalogue is not penalised as much for its breadth. Lab 5.8 to 6.9.

     BioRegen certificates confirmed at the laboratory's own lookup on 22 October 2026 (an invented test key returned no match), so they now receive the confirmed-key credit under our published lab rule. Lab 5.7 to 5.8.

209. October 22, 2026NextGen PepsUp 5.67 → 5.73 (+0.06)

     Re-scored on 22 October 2026 under version 2 of our published rules. The deduction for verification codes the laboratory could not find was retired: each such certificate now keeps its points for the printed key and earns none for confirmation, and codes on certificates we do not score no longer count.

     Lab score recalculated on 22 October 2026 under the uniform published rubric applied to every vendor: every listed product was rescored on the same fixed certificate points, with fixed deductions for certificates more than 12 months old, one lot number printed on certificates for different compounds, site statements about testing that the certificates do not bear out and verification codes the issuing laboratory could not find. Lab 7.4 to 7.1.

216. October 22, 2026NuScience PeptidesUp 6.54 → 6.65 (+0.11)

     Lab evidence re-checked on 20 October 2026 under our coverage rule, which counts a listed product with no published certificate as zero in the lab average. Certificates cover 17 of the 17 products we list that the vendor offers for sale. Lab 7.2 to 7.4.

220. October 22, 2026Oasis LabsDown 7.14 → 7.03 (-0.11)

     Laboratory grades re-checked on 22 October 2026 under the published laboratory rulebook (checks L1 to L6 on How We Rate). BioChex's only report, for Oasis Labs retatrutide, was issued a few hours before the biochex.org domain printed on it was registered, and no other client was found, so its independence is not established (check L2): the certificate now scores the flat 2.0 (rule A3) and no longer counts toward the testing gate, which Oasis Labs still meets with 17 of 18 products. Separately, the printed October 2025 date on the Bioviridian sermorelin certificate (COA3255) was found to be a misprint contradicted by the laboratory's own records, so its March 2026 run date is used and it no longer counts as older than 12 months. Lab 8.0 to 7.8.

221. October 22, 2026Oasis LabsDown 7.24 → 7.14 (-0.10)

     Re-scored on 22 October 2026 under our published rubric for shipping, pricing, operating history and transparency, applied to every vendor the same day: prices re-read from the vendor's site and matched by milligrams per vial, operating history from the earliest dated evidence of the business, and policies scored item by item. shipping and refunds 5.5 to 8.0, pricing 2.5 to 2.2, operating history 0.5 to 0.9, transparency 1.5 to 2.0.

239. October 22, 2026Peptara LabsUp 2.66 → 2.71 (+0.05)

     Lab score recalculated on 22 October 2026 under the published core-product rule (A1b): a missing certificate on one of the 15 most widely carried products still counts fully, while on any other product it now counts at half weight, so a broad catalogue is not penalised as much for its breadth. Lab 1.7 to 1.8.

240. October 22, 2026Peptara LabsDown 2.79 → 2.66 (-0.13)

     Re-scored on 22 October 2026 under our published rubric for shipping, pricing, operating history and transparency, applied to every vendor the same day: prices re-read from the vendor's site and matched by milligrams per vial, operating history from the earliest dated evidence of the business, and policies scored item by item. shipping and refunds 5.0 to 6.0, pricing 4.0 to 1.2, operating history 1.5 to 1.3, transparency 3.5 to 5.5.

241. October 22, 2026Peptara LabsUp 1.85 → 2.79 (+0.94)

     Lab score recalculated on 22 October 2026 under the uniform published rubric applied to every vendor: the published certificates, which our 1 October 2026 audit could not tie to an independent operating laboratory, now score the fixed 2.0 the rubric gives documents whose laboratory independence is not established, instead of zero. Lab 0.0 to 1.7.

242. October 22, 2026Peptide LabsUp 3.58 → 3.69 (+0.11)

     Lab score recalculated on 22 October 2026 under the published core-product rule (A1b): a missing certificate on one of the 15 most widely carried products still counts fully, while on any other product it now counts at half weight, so a broad catalogue is not penalised as much for its breadth. Lab 1.6 to 1.8.

243. October 22, 2026Peptide LabsUp 3.29 → 3.58 (+0.29)

     Re-scored on 22 October 2026 under our published rubric for shipping, pricing, operating history and transparency, applied to every vendor the same day: prices re-read from the vendor's site and matched by milligrams per vial, operating history from the earliest dated evidence of the business, and policies scored item by item. shipping and refunds 5.5 to 8.0, pricing 7.3 to 6.1, transparency 2.0 to 1.5.

244. October 22, 2026Peptide ProsUp 3.47 → 3.58 (+0.11)

     Lab score recalculated on 22 October 2026 under the published core-product rule (A1b): a missing certificate on one of the 15 most widely carried products still counts fully, while on any other product it now counts at half weight, so a broad catalogue is not penalised as much for its breadth. Lab 1.1 to 1.3. Note added 22 October 2026: a score on this entry was corrected from 3.57 to 3.58; it had been rounded down instead of half up.

245. October 22, 2026Peptide ProsDown 3.67 → 3.47 (-0.20)

     Re-scored on 22 October 2026 under the published rulebook, which now gives one rule for each judgement call and applies it to every vendor: shipping and refunds 6.5 to 5.5.

246. October 22, 2026Peptide ProsUp 3.56 → 3.67 (+0.11)

     Re-scored on 22 October 2026 under our published rubric for shipping, pricing, operating history and transparency, applied to every vendor the same day: prices re-read from the vendor's site and matched by milligrams per vial, operating history from the earliest dated evidence of the business, and policies scored item by item. shipping and refunds 5.5 to 6.5, pricing 7.7 to 6.8, operating history 9.0 to 9.3, transparency 5.0 to 5.5.

247. October 22, 2026Peptide ProsUp 3.40 → 3.56 (+0.16)

     Lab score recalculated on 22 October 2026 under the uniform published rubric applied to every vendor: every listed product was rescored on the same fixed certificate points, with fixed deductions for certificates more than 12 months old, site statements about testing that the certificates do not bear out and one lot number printed on certificates for different compounds. Lab 0.8 to 1.1.

248. October 22, 2026Peptide ProsDown 3.78 → 3.40 (-0.38)

     Lab evidence re-checked on 22 October 2026 under our coverage rule. The certificates linked on the site carry no verification key and are four to five years old, and most listed products show none, so lab moves from 1.5 to 0.8.

249. October 22, 2026Peptide WarehouseUp 5.00 → 5.06 (+0.06)

     Lab score recalculated on 22 October 2026 under the published core-product rule (A1b): a missing certificate on one of the 15 most widely carried products still counts fully, while on any other product it now counts at half weight, so a broad catalogue is not penalised as much for its breadth. Lab 3.8 to 3.9. Note added 22 October 2026: a score on this entry was corrected from 5.05 to 5.06; it had been rounded down instead of half up.

250. October 22, 2026Peptide WarehouseUp 4.93 → 5.00 (+0.07)

     Operating history re-checked on 22 October 2026 under the published rule (earliest dated evidence of the business, including a never-parked store domain and the named operating company, looked up for every vendor): operating history 0.8 to 2.3.

251. October 22, 2026Peptide WarehouseUp 4.86 → 4.93 (+0.07)

     Every listed product read and its certificate confirmed at the issuing laboratory on 22 October 2026 (the site was previously unreadable to our tools), so the lab score now follows our published lab rule. Lab 3.7 to 3.8. Note added 22 October 2026: a score on this entry was corrected from 4.92 to 4.93; it had been rounded down instead of half up.

     Lab score recalculated on 22 October 2026 under the published core-product rule (A1b): a missing certificate on one of the 15 most widely carried products still counts fully, while on any other product it now counts at half weight, so a broad catalogue is not penalised as much for its breadth. Lab 1.2 to 1.5.

255. October 22, 2026Peptide.ExpressUp 3.15 → 3.50 (+0.35)

     Lab score recalculated on 22 October 2026 under the uniform published rubric applied to every vendor: the Mistral Diagnostics certificates now score the fixed 2.0 the rubric gives a laboratory whose independence we could not establish; fixed deductions apply for one lot number printed on certificates for different compounds. Lab 1.7 to 1.2.

258. October 22, 2026Peptides SourceDown 7.55 → 7.44 (-0.11)

     Certificates issued to other businesses (NxGen Bio Med, P4R Wholesale, SW Peptides) appear on some product pages, confirmed live on 22 October 2026: a fixed supplier deduction under our published lab rule. Lab 8.3 to 8.1.

259. October 22, 2026Peptides SourceUp 7.48 → 7.53 (+0.05)

     Claim deductions re-checked on 22 October 2026 under the published rule that a claim deduction applies only where a site claim is contradicted by what its certificates show, never for products merely lacking a certificate. Lab 8.2 to 8.3.

260. October 22, 2026Peptides SourceUp 7.43 → 7.48 (+0.05)

     Re-scored on 22 October 2026 under the published rulebook, which now gives one rule for each judgement call and applies it to every vendor: transparency 2.0 to 3.0.

     Re-scored on 22 October 2026 under version 2 of our published rules. The deduction for verification codes the laboratory could not find was retired: each such certificate now keeps its points for the printed key and earns none for confirmation, and codes on certificates we do not score no longer count. Lab 7.9 to 8.2. Score 7.26 to 7.43.

262. October 22, 2026Peptides SourceDown 7.69 → 7.26 (-0.43)

270. October 22, 2026Pinnacle Peptide LabsUp 6.21 → 6.43 (+0.22)

     Re-scored on 22 October 2026 under version 2 of our published rules. The deduction for posted copies that differ from the laboratory's record was retired; the two affected products (CJC-1295 and GHK-Cu) already score 0 because no certificate for the single product is published. Lab 6.4 to 6.8. Score 6.21 to 6.43.

271. October 22, 2026Pinnacle Peptide LabsDown 6.74 → 6.21 (-0.53)

     Re-scored on 22 October 2026 under our published rubric for shipping, pricing, operating history and transparency, applied to every vendor the same day: prices re-read from the vendor's site and matched by milligrams per vial, operating history from the earliest dated evidence of the business, and policies scored item by item. shipping and refunds 7.5 to 7.0, pricing 8.5 to 5.8, operating history 2.0 to 1.8, transparency 7.0 to 6.5.

272. October 22, 2026Pinnacle Peptide LabsUp 6.69 → 6.74 (+0.05)

     Lab score recalculated on 22 October 2026 under the uniform published rubric applied to every vendor: every listed product was rescored on the same fixed certificate points, with fixed deductions for posted certificate copies that differ from the laboratory's own copy and certificates ordered by a supplier or issued to another business. Lab 6.3 to 6.4.

273. October 22, 2026Prime Lab PeptidesUp 6.26 → 6.48 (+0.22)

     Lab deductions independently re-verified from primary sources on 22 October 2026; a deduction that could not be confirmed was removed or reduced. Lab 6.5 to 6.9.

     Lab score recalculated on 22 October 2026 under the published core-product rule (A1b): a missing certificate on one of the 15 most widely carried products still counts fully, while on any other product it now counts at half weight, so a broad catalogue is not penalised as much for its breadth. Lab 3.8 to 4.4.

277. October 22, 2026Prime Peptide SolutionsUp 5.22 → 5.27 (+0.05)

     Claim deductions re-checked on 22 October 2026 under the published rule that a claim deduction applies only where a site claim is contradicted by what its certificates show, never for products merely lacking a certificate. Lab 3.7 to 3.8.

278. October 22, 2026Prime Peptide SolutionsDown 5.50 → 5.17 (-0.33)

     Lab score recalculated on 22 October 2026 under the uniform published rubric applied to every vendor: ILS Laboratories, which issued certificates relied on here, does not publish ISO/IEC 17025 accreditation, so the accreditation point no longer applies; fixed deductions apply for site statements about testing that the certificates do not bear out and one lot number printed on certificates for different compounds. Lab 4.3 to 3.7. Note added 22 October 2026: PJLA's register lists ILS Laboratories' accreditation (certificate L25-631) as suspended from 22 October 2026; the accreditation point still does not apply (check L6).

Note added 22 October 2026: a score on this entry was corrected from 8.14 to 8.15; it had been rounded down instead of half up.

281. October 22, 2026Prime PeptidesUp 7.67 → 8.00 (+0.33)

     Janoshik certificates confirmed on 22 October 2026 at the laboratory's own verification site, so each confirmed report now earns the key-confirmed credit under our published lab rule. Lab 8.1 to 8.7.

282. October 22, 2026Prime PeptidesUp 7.62 → 7.67 (+0.05)

     Lab score recalculated on 22 October 2026 under the uniform published rubric applied to every vendor: every listed product was rescored on the same fixed certificate points, with fixed deductions for site statements about testing that the certificates do not bear out. Lab 8.0 to 8.1.

283. October 22, 2026Prism LabsUp 3.78 → 3.98 (+0.20)

     Lab score recalculated on 22 October 2026 under the uniform published rubric applied to every vendor: certificates from Proof Point Analytical, which we could not establish as an independent laboratory, now score the fixed 2.0 the rubric gives such documents, replacing an earlier discretionary deduction. Lab 1.0 to 2.0.

286. October 22, 2026Profound AminosUp 6.51 → 6.68 (+0.17)

     Re-scored on 22 October 2026 under version 2 of our published rules. The deduction for verification codes the laboratory could not find was retired: each such certificate now keeps its points for the printed key and earns none for confirmation, and codes on certificates we do not score no longer count. Lab 7.6 to 7.9. Score 6.51 to 6.68.

287. October 22, 2026Profound AminosDown 6.66 → 6.51 (-0.15)

289. October 22, 2026Profound AminosDown 6.83 → 6.77 (-0.06)

     Lab score recalculated on 22 October 2026 under the uniform published rubric applied to every vendor: every listed product was rescored on the same fixed certificate points, with fixed deductions for certificates more than 12 months old, site statements about testing that the certificates do not bear out, verification codes the issuing laboratory could not find and one lot number printed on certificates for different compounds. Lab 7.7 to 7.6.

290. October 22, 2026Profound AminosUp 6.66 → 6.83 (+0.17)

     Lab evidence re-checked on 20 October 2026 under our coverage rule, which counts a listed product with no published certificate as zero in the lab average. Certificates cover 17 of the 17 products we list that the vendor offers for sale. Lab 7.4 to 7.7.

     Lab score recalculated on 22 October 2026 under the uniform published rubric applied to every vendor: the microbial PCR screen on its certificates now earns the sterility-screen point, and an earlier discretionary hold was removed. Lab 8.4 to 9.1.

293. October 22, 2026PSPeptidesDown 4.01 → 3.95 (-0.06)

     Laboratory grades re-checked on 22 October 2026 under the published laboratory rulebook (checks L1 to L6 on How We Rate). Vanguard Laboratory's A2LA accreditation does not cover peptide testing (its scope lists microbiology, trace elements, preservatives and residual solvents), so its certificates no longer earn the accreditation point (check L6); its identity test is by HPLC retention time (check L4), which grades it B+. This affects one PSPeptides certificate (retatrutide). Lab 2.3 to 2.2.

294. October 22, 2026PSPeptidesDown 4.06 → 4.01 (-0.05)

     Claim deductions re-checked on 22 October 2026 under the published rule (only site claims contradicted by what the certificates show), each confirmed independently from primary sources.

     Laboratory grades re-checked on 22 October 2026 under the published laboratory rulebook (checks L1 to L6 on How We Rate). Ethos Analytics Laboratory's PJLA accreditation covers supplement, botanical and cosmetic testing but not peptides, so its certificates no longer earn the accreditation point (check L6); its identity test is by HPLC retention time (check L4), which grades it B+. This affects 19 Pure Health Peptides certificates. Lab 8.9 to 8.0.

301. October 22, 2026Pure Health PeptidesDown 8.50 → 8.39 (-0.11)

     Claim deductions re-checked on 22 October 2026 under the published rule (only site claims contradicted by what the certificates show), each confirmed independently from primary sources. Lab 9.1 to 8.9.

302. October 22, 2026Pure Health PeptidesUp 8.33 → 8.48 (+0.15)

     Re-scored on 22 October 2026 under our published rubric for shipping, pricing, operating history and transparency, applied to every vendor the same day: prices re-read from the vendor's site and matched by milligrams per vial, operating history from the earliest dated evidence of the business, and policies scored item by item. shipping and refunds 7.9 to 8.5, pricing 9.0 to 9.2, operating history 2.0 to 2.9, transparency 5.9 to 5.0.

303. October 22, 2026Pure Health PeptidesUp 7.85 → 8.33 (+0.48)

     Lab evidence re-checked on 20 October 2026 under our coverage rule, which counts a listed product with no published certificate as zero in the lab average. Certificates cover 21 of the 21 products we list that the vendor offers for sale. Lab 8.2 to 9.1.

304. October 22, 2026Pure Health PeptidesUp 6.50 → 7.85 (+1.35)

     Store back online on 22 October 2026 at purehealthpeptides.co; the former purehealthpeptides.com domain now redirects there. With the store and its certificates available to check again, the third-party cap applied while the site was offline was lifted. The subscores were unchanged. Score 6.50 to 7.85.

305. October 22, 2026RapidCore BioUp 3.16 → 3.22 (+0.06)

     Lab score recalculated on 22 October 2026 under the published core-product rule (A1b): a missing certificate on one of the 15 most widely carried products still counts fully, while on any other product it now counts at half weight, so a broad catalogue is not penalised as much for its breadth. Lab 1.1 to 1.2.

306. October 22, 2026RapidCore BioUp 2.98 → 3.16 (+0.18)

     Re-scored on 22 October 2026 under our published rubric for shipping, pricing, operating history and transparency, applied to every vendor the same day: prices re-read from the vendor's site and matched by milligrams per vial, operating history from the earliest dated evidence of the business, and policies scored item by item. shipping and refunds 5.0 to 6.5, pricing 8.0 to 7.6, operating history 1.0 to 1.4, transparency 2.5 to 1.0.

307. October 22, 2026RapidCore BioUp 2.92 → 2.98 (+0.06)

     Lab score recalculated on 22 October 2026 under the uniform published rubric applied to every vendor: every listed product was rescored on the same fixed certificate points, with fixed deductions for one lot number printed on certificates for different compounds and site statements about testing that the certificates do not bear out. Lab 1.0 to 1.1.

308. October 22, 2026Raw AminoDown 5.97 → 5.86 (-0.11)

     Supplier adjustment added (-0.2, rule A7): six MZ Biolabs analyses on Raw Amino's certificates (TB-500, GHK-Cu, CJC-1295 with DAC, Ipamorelin, PT-141 and Hexarelin) were first issued to another business in July 2026 and re-issued under Raw Amino's name on 2 September 2026 with new lot labels, as the laboratory's own records show. Confirmed independently twice. Lab 6.2 to 6.0.

309. October 22, 2026Raw AminoUp 5.91 → 5.97 (+0.06)

     Lab score recalculated on 22 October 2026 under the published core-product rule (A1b): a missing certificate on one of the 15 most widely carried products still counts fully, while on any other product it now counts at half weight, so a broad catalogue is not penalised as much for its breadth.

312. October 22, 2026Raw AminoUp 6.28 → 6.83 (+0.55)

     Certificate verification keys confirmed on 22 October 2026 at MZ Biolabs' own certificate page, which only opens in a browser, and the lab score recalculated under the uniform rubric. Lab 5.2 to 6.2.

313. October 22, 2026Raw AminoUp 5.89 → 6.28 (+0.39)

     Lab evidence re-checked on 20 October 2026 under our coverage rule, which counts a listed product with no published certificate as zero in the lab average. Certificates cover 15 of the 17 products we list that the vendor offers for sale. Lab 4.5 to 5.2.

314. October 22, 2026Redline Bio LabsUp 4.10 → 4.21 (+0.11)

     Lab score recalculated on 22 October 2026 under the published core-product rule (A1b): a missing certificate on one of the 15 most widely carried products still counts fully, while on any other product it now counts at half weight, so a broad catalogue is not penalised as much for its breadth.

315. October 22, 2026Redline Bio LabsDown 4.20 → 4.10 (-0.10)

     Re-scored on 22 October 2026 under the published rulebook, which now gives one rule for each judgement call and applies it to every vendor: shipping and refunds 7.0 to 6.5.

316. October 22, 2026Redline Bio LabsUp 4.14 → 4.20 (+0.06)

     Laboratory directory completed on 22 October 2026: AV Analytics and Analiza Bialek were researched and added under the published lab criteria, so their certificates now receive the recognised-laboratory credit. Lab 2.3 to 2.4.

317. October 22, 2026Redline Bio LabsUp 3.98 → 4.14 (+0.16)

     Lab deductions independently re-verified from primary sources on 22 October 2026; a deduction that could not be confirmed was removed or reduced. Lab 2.0 to 2.3.

318. October 22, 2026Redline Bio LabsUp 3.68 → 3.98 (+0.30)

     Re-scored on 22 October 2026 under our published rubric for shipping, pricing, operating history and transparency, applied to every vendor the same day: prices re-read from the vendor's site and matched by milligrams per vial, operating history from the earliest dated evidence of the business, and policies scored item by item. shipping and refunds 5.5 to 7.0, pricing 8.0 to 7.6, operating history 1.0 to 1.8, transparency 4.5 to 5.0.

319. October 22, 2026Redline Bio LabsDown 3.95 → 3.68 (-0.27)

     Lab score recalculated on 22 October 2026 under the uniform published rubric applied to every vendor: every listed product was rescored on the same fixed certificate points, with fixed deductions for site statements about testing that the certificates do not bear out and verification codes the issuing laboratory could not find. Lab 2.5 to 2.0.

320. October 22, 2026Research Peptides LabUp 5.98 → 6.16 (+0.18)

     Re-scored on 22 October 2026 under the published rulebook, which now gives one rule for each judgement call and applies it to every vendor: shipping and refunds 5.5 to 6.5, transparency 1.5 to 1.0.

321. October 22, 2026Research Peptides LabUp 5.71 → 5.98 (+0.27)

     Every listed product read and its certificate confirmed at the issuing laboratory on 22 October 2026 (the site was previously unreadable to our tools), so the lab score now follows our published lab rule. Lab 6.5 to 7.0.

322. October 22, 2026Research Peptides LabDown 6.14 → 5.71 (-0.43)

     Re-scored on 22 October 2026 under our published rubric for shipping, pricing, operating history and transparency, applied to every vendor the same day: prices re-read from the vendor's site and matched by milligrams per vial, operating history from the earliest dated evidence of the business, and policies scored item by item. shipping and refunds 5.8 to 5.5, pricing 7.8 to 5.8, operating history 2.2 to 1.7, transparency 2.5 to 1.5.

323. October 22, 2026Southern AminosUp 8.03 → 8.14 (+0.11)

     Lab score recalculated on 22 October 2026 under the published core-product rule (A1b): a missing certificate on one of the 15 most widely carried products still counts fully, while on any other product it now counts at half weight, so a broad catalogue is not penalised as much for its breadth. Lab 8.8 to 9.0.

324. October 22, 2026Southern AminosUp 7.85 → 8.03 (+0.18)

     Re-scored on 22 October 2026 under the published rulebook, which now gives one rule for each judgement call and applies it to every vendor: shipping and refunds 6.5 to 7.5, transparency 5.5 to 5.0.

325. October 22, 2026Southern AminosUp 7.58 → 7.85 (+0.27)

     Re-scored on 22 October 2026 under version 2 of our published rules. The deduction for verification codes the laboratory could not find was retired: each such certificate now keeps its points for the printed key and earns none for confirmation, and codes on certificates we do not score no longer count; the deduction for the PT-141 copy was also retired, because that lot is not the scored PT-141 certificate. Lab 8.3 to 8.8. Score 7.58 to 7.85.

326. October 22, 2026Southern AminosDown 7.81 → 7.54 (-0.27)

     Lab score recalculated on 22 October 2026 under the uniform published rubric applied to every vendor: every listed product was rescored on the same fixed certificate points, with fixed deductions for verification codes the issuing laboratory could not find and posted certificate copies that differ from the laboratory's own copy. Lab 8.8 to 8.3.

327. October 22, 2026Spartan PeptidesUp 2.66 → 2.94 (+0.28)

     Lab score recalculated on 22 October 2026 under the published core-product rule (A1b): a missing certificate on one of the 15 most widely carried products still counts fully, while on any other product it now counts at half weight, so a broad catalogue is not penalised as much for its breadth. Lab 2.1 to 2.6.

328. October 22, 2026Spartan PeptidesUp 2.55 → 2.66 (+0.11)

     Claim deductions re-checked on 22 October 2026 under the published rule that a claim deduction applies only where a site claim is contradicted by what its certificates show, never for products merely lacking a certificate. Lab 1.9 to 2.1.

329. October 22, 2026Spartan PeptidesUp 2.36 → 2.58 (+0.22)

     Re-scored on 22 October 2026 under version 2 of our published rules. The MZ Biolabs certificate IDs for BPC-157, GHK-Cu and Tesamorelin were confirmed at the laboratory, which raises those certificates. The testing gate is now computed from the certificates: 3 of 13 products have a certificate confirmed at a directory laboratory, fewer than the half required. Lab 1.5 to 1.9. Score 2.36 to 2.58.

330. October 22, 2026Spartan PeptidesDown 3.34 → 2.36 (-0.98)

     Re-scored on 22 October 2026 under our published rubric for shipping, pricing, operating history and transparency, applied to every vendor the same day: prices re-read from the vendor's site and matched by milligrams per vial, operating history from the earliest dated evidence of the business, and policies scored item by item. shipping and refunds 6.5 to 5.5, pricing 3.3 to 1.0, operating history 9.0 to 3.1, transparency 5.3 to 2.5.

331. October 22, 2026Spartan PeptidesDown 3.39 → 3.34 (-0.05)

     Lab score recalculated on 22 October 2026 under the uniform published rubric applied to every vendor: every listed product was rescored on the same fixed certificate points, with fixed deductions for one lot number printed on certificates for different compounds and site statements about testing that the certificates do not bear out. Lab 1.6 to 1.5.

332. October 22, 2026Sports Technology LabsUp 6.89 → 7.05 (+0.16)

     Lab score recalculated on 22 October 2026 under the published core-product rule (A1b): a missing certificate on one of the 15 most widely carried products still counts fully, while on any other product it now counts at half weight, so a broad catalogue is not penalised as much for its breadth. Lab 6.5 to 6.8.

333. October 22, 2026Sports Technology LabsUp 6.40 → 6.88 (+0.48)

     Re-scored on 22 October 2026 under our published rubric for shipping, pricing, operating history and transparency, applied to every vendor the same day: prices re-read from the vendor's site and matched by milligrams per vial, operating history from the earliest dated evidence of the business, and policies scored item by item. shipping and refunds 7.0 to 10.0, pricing 5.5 to 5.2, transparency 5.0 to 3.5.

     Certificate verification keys confirmed on 22 October 2026 at MZ Biolabs' own certificate page, which only opens in a browser, and the lab score recalculated under the uniform rubric. Lab 5.3 to 6.5.

335. October 22, 2026Sports Technology LabsDown 5.85 → 5.74 (-0.11)

     Lab score recalculated on 22 October 2026 under the uniform published rubric applied to every vendor: every listed product was rescored on the same fixed certificate points, with fixed deductions for certificates more than 12 months old, one lot number printed on certificates for different compounds and site statements about testing that the certificates do not bear out. Lab 5.5 to 5.3.

336. October 22, 2026Sports Technology LabsDown 6.01 → 5.85 (-0.16)

     Lab evidence re-checked on 20 October 2026 under our coverage rule, which counts a listed product with no published certificate as zero in the lab average. Certificates cover 15 of the 16 products we list that the vendor offers for sale. Lab 5.8 to 5.5.

337. October 22, 2026Swiss ChemsUp 5.00 → 5.50 (+0.50)

     Lab score recalculated on 22 October 2026 under the published core-product rule (A1b): a missing certificate on one of the 15 most widely carried products still counts fully, while on any other product it now counts at half weight, so a broad catalogue is not penalised as much for its breadth. Lab 3.9 to 4.8.

338. October 22, 2026Swiss ChemsDown 5.16 → 4.99 (-0.17)

     Re-scored on 22 October 2026 under version 2 of our published rules. Sermorelin's only document is a heavy-metals screen, which is not a certificate of identity or purity, so the product now scores 0; the MOTS-c and ARA-290 documents name no laboratory and now score the flat 2.0 that applies to every certificate whose source cannot be established. The testing gate is now computed from the certificates: 16 of 33 products have a certificate confirmed at a directory laboratory, fewer than the half required, so the testing cap applies; it sits above the weighted score, so it does not lower it. Lab 4.2 to 3.9. Score 5.16 to 4.99.

339. October 22, 2026Swiss ChemsUp 4.93 → 5.16 (+0.23)

     Lab deductions independently re-verified from primary sources on 22 October 2026; a deduction that could not be confirmed was removed or reduced. Lab 3.8 to 4.2.

340. October 22, 2026Swiss ChemsDown 5.54 → 4.93 (-0.61)

     Re-scored on 22 October 2026 under our published rubric for shipping, pricing, operating history and transparency, applied to every vendor the same day: prices re-read from the vendor's site and matched by milligrams per vial, operating history from the earliest dated evidence of the business, and policies scored item by item. shipping and refunds 7.0 to 6.5, pricing 8.5 to 7.0, operating history 8.5 to 7.4, transparency 7.0 to 2.5.

341. October 22, 2026Swiss ChemsDown 5.65 → 5.54 (-0.11)

     Lab score recalculated on 22 October 2026 under the uniform published rubric applied to every vendor: every listed product was rescored on the same fixed certificate points, with fixed deductions for certificates more than 12 months old, site statements about testing that the certificates do not bear out and certificates ordered by a supplier or issued to another business. Lab 4.0 to 3.8.

342. October 22, 2026Swiss ChemsUp 4.99 → 5.65 (+0.66)

     Lab evidence re-checked on 20 October 2026 under our coverage rule, which counts a listed product with no published certificate as zero in the lab average. Certificates cover 19 of the 33 products we list that the vendor offers for sale. Lab 2.8 to 4.0.

     Claim deductions re-checked on 22 October 2026 under the published rule (only site claims contradicted by what the certificates show), each confirmed independently from primary sources. Lab 8.1 to 7.9.

344. October 22, 2026Thrive PeptidesDown 7.72 → 7.44 (-0.28)

     Re-scored on 22 October 2026 under our published rubric for shipping, pricing, operating history and transparency, applied to every vendor the same day: prices re-read from the vendor's site and matched by milligrams per vial, operating history from the earliest dated evidence of the business, and policies scored item by item. shipping and refunds 7.5 to 6.0, pricing 8.5 to 9.0, operating history 3.3 to 1.7, transparency 6.5 to 7.0.

345. October 22, 2026Transition BiotechUp 7.91 → 7.98 (+0.07)

     Re-scored on 22 October 2026 under our published rubric for shipping, pricing, operating history and transparency, applied to every vendor the same day: prices re-read from the vendor's site and matched by milligrams per vial, operating history from the earliest dated evidence of the business, and policies scored item by item. shipping and refunds 5.3 to 6.0, transparency 5.5 to 4.0. Note added 22 October 2026: a score on this entry was corrected from 7.97 to 7.98; it had been rounded down instead of half up.

346. October 22, 2026Transition BiotechUp 7.60 → 7.87 (+0.27)

     Lab score recalculated on 22 October 2026 under the uniform published rubric applied to every vendor: the rapid sterility screen on its Kovera Labs certificates now earns the sterility-screen point. Lab 8.7 to 9.2.

347. October 22, 2026VERATISDown 7.29 → 7.24 (-0.05)

     Claim deductions re-checked on 22 October 2026 under the published rule (only site claims contradicted by what the certificates show), each confirmed independently from primary sources. Lab 8.8 to 8.7.

348. October 22, 2026VERATISDown 7.54 → 7.32 (-0.22)

     Re-scored on 22 October 2026 under our published rubric for shipping, pricing, operating history and transparency, applied to every vendor the same day: prices re-read from the vendor's site and matched by milligrams per vial, operating history from the earliest dated evidence of the business, and policies scored item by item. pricing 6.5 to 6.3, operating history 1.5 to 1.1, transparency 7.0 to 3.5.

349. October 22, 2026VERATISUp 7.21 → 7.54 (+0.33)

     Lab score recalculated on 22 October 2026 under the uniform published rubric applied to every vendor: earlier judgement deductions that are not part of the published rubric were removed. Lab 8.2 to 8.8.

350. October 22, 2026Verified PeptidesDown 7.76 → 7.70 (-0.06)

     Claim deductions re-checked on 22 October 2026 under the published rule (only site claims contradicted by what the certificates show), each confirmed independently from primary sources. Lab 8.3 to 8.2. Note added 22 October 2026: a score on this entry was corrected from 7.75 to 7.76; it had been rounded down instead of half up.

351. October 22, 2026Verified PeptidesDown 7.85 → 7.72 (-0.13)

     Re-scored on 22 October 2026 under our published rubric for shipping, pricing, operating history and transparency, applied to every vendor the same day: prices re-read from the vendor's site and matched by milligrams per vial, operating history from the earliest dated evidence of the business, and policies scored item by item. shipping and refunds 7.3 to 7.5, pricing 8.2 to 8.1, operating history 7.0 to 6.2, transparency 5.0 to 2.5.

     Janoshik certificates confirmed on 22 October 2026 at the laboratory's own verification site, so each confirmed report now earns the key-confirmed credit under our published lab rule. Lab 6.8 to 8.3.

353. October 22, 2026Verified PeptidesDown 7.08 → 7.03 (-0.05)

     Lab score recalculated on 22 October 2026 under the uniform published rubric applied to every vendor: every listed product was rescored on the same fixed certificate points, with fixed deductions for certificates more than 12 months old. Lab 6.9 to 6.8.

354. October 22, 2026Verified PeptidesDown 8.11 → 7.08 (-1.03)

     Re-audited in full in October 2026; the July scores had no recorded audit trail. Lab 7.0 to 6.9: certificates are newer and endotoxin now matches the purity batch, but no key could be checked with the laboratory and some page claims of sterility testing are not backed by a matching report. Shipping 10 to 7.3: a seven-day return window with a prepaid label, but lost-parcel handling is discretionary, damage is not addressed, and the terms of use say all sales are final. Pricing 9.5 to 8.2: prices sit below the market on most products, in line with similarly priced vendors. Tenure 7.2 to 7.0: domain registered October 2019. Transparency 9.5 to 5.0: no company name, address, phone or named owner is published.

356. October 22, 2026VoriLabsDown 6.98 → 6.81 (-0.17)

     Lab evidence re-checked on 20 October 2026 under our coverage rule, which counts a listed product with no published certificate as zero in the lab average. Certificates cover 27 of the 27 products we list that the vendor offers for sale. Lab 7.5 to 7.2.

357. October 22, 2026Vyal LabsUp 4.39 → 4.61 (+0.22)

     Lab score recalculated on 22 October 2026 under the published core-product rule (A1b): a missing certificate on one of the 15 most widely carried products still counts fully, while on any other product it now counts at half weight, so a broad catalogue is not penalised as much for its breadth. Lab 3.4 to 3.8. Note added 22 October 2026: a score on this entry was corrected from 4.38 to 4.39; it had been rounded down instead of half up. Note added 22 October 2026: a score on this entry was corrected from 4.60 to 4.61; it had been rounded down instead of half up.

     Re-scored on 22 October 2026 under the published rulebook, which now gives one rule for each judgement call and applies it to every vendor: shipping and refunds 4.0 to 7.0.

362. October 22, 2026YourFitnessPeptidesUp 2.00 → 2.23 (+0.23)

     Re-scored on 22 October 2026 under our published rubric for shipping, pricing, operating history and transparency, applied to every vendor the same day: prices re-read from the vendor's site and matched by milligrams per vial, operating history from the earliest dated evidence of the business, and policies scored item by item. shipping and refunds 3.5 to 4.0, pricing 7.5 to 8.3, operating history 1.5 to 1.6.

363. October 22, 2026Zeptix LabsUp 6.01 → 6.18 (+0.17)

     Lab score recalculated on 22 October 2026 under the published core-product rule (A1b): a missing certificate on one of the 15 most widely carried products still counts fully, while on any other product it now counts at half weight, so a broad catalogue is not penalised as much for its breadth. Lab 6.4 to 6.7.

364. October 22, 2026Zeptix LabsDown 6.85 → 6.01 (-0.84)

     Re-scored on 22 October 2026 under our published rubric for shipping, pricing, operating history and transparency, applied to every vendor the same day: prices re-read from the vendor's site and matched by milligrams per vial, operating history from the earliest dated evidence of the business, and policies scored item by item. shipping and refunds 8.5 to 5.5, pricing 8.0 to 7.0, operating history 2.0 to 1.3, transparency 6.5 to 5.5.

365. October 22, 2026Zeptix LabsUp 6.74 → 6.85 (+0.11)

     Lab score recalculated on 22 October 2026 under the uniform published rubric applied to every vendor: every listed product was rescored on the same fixed certificate points, with fixed deductions for site statements about testing that the certificates do not bear out. Lab 6.2 to 6.4.

366. October 21, 2026Ameano PeptidesDown 8.04 → 7.29 (-0.75)

     Lab 7 to 5.9 and tenure 5.9 to 2.8. Recomputed under our published rule, which averages the lab score over the products we list and counts a listed product with no certificate as zero: the certificate links for ARA-290 and AHK-Cu did not lead to certificates for those products and Bronchogen has none, and the Janoshik reports could not be checked at the laboratory. The domain was registered in January 2025, so the operating-history score was aligned to that date.

367. October 21, 2026Amino ClubUp 8.49 → 8.66 (+0.17)

     Catalogue imported and every certificate checked on 21 October 2026: 38 peptide products listed, each with an ILS Laboratories certificate, and all 103 certificates in the library matched the issuing laboratories' records. Lab 8.9 to 9.2. Pricing unchanged pending a size-by-size price read.

368. October 21, 2026AminoVaultDown 6.94 → 5.95 (-0.99)

     Lab 7.2 to 5.4. Recomputed under our published rule, which averages the lab score over the products we list and counts a listed product with no certificate as zero. Two August 2026 ILS Laboratories certificates for ARA-290 and the BPC-157/TB-500 blend were added and confirmed at the laboratory's portal, and an MDx certificate was added for SLU-PP-332. The CJC-1295/Ipamorelin blend now counts as having no certificate, because the page linked the single-peptide CJC-1295 report. None of the other certificates was confirmed at the issuing laboratory, and nine are more than 12 months old.

369. October 21, 2026AnhydrolabsDown 2.80 → 2.52 (-0.28)

     Lab 0.5 to 0. The vendor publishes no laboratory reports, which it states openly, and under our published rule the lab score is zero rather than a small floor.

370. October 21, 2026Ascension PeptidesUp 7.86 → 8.53 (+0.67)

     Lab evidence re-checked on 20 October 2026 under our coverage rule, which counts a listed product with no published certificate as zero in the lab average. Certificates cover 30 of the 30 products we list that the vendor offers for sale. Lab 7.8 to 9.0.

371. October 21, 2026BioInfinityDown 8.48 → 7.31 (-1.17)

     Lab 8.3 to 6.4 and tenure 4.6 to 2.2. Recomputed under our published rule, which averages the lab score over the products we list and counts a listed product with no certificate as zero. DSIP and the CJC-1295/Ipamorelin blend count as having no certificate: an automated backfill on 18 October 2026 had restored a DSIP record that our 8 October correction removed, and that reversal has been undone. The Verum records could not be confirmed at the laboratory. Both domains were registered in August and September 2025, so tenure was aligned to that age.

372. October 21, 2026BioLongevity LabsDown 7.94 → 7.83 (-0.11)

     Lab evidence re-checked on 20 October 2026 under our coverage rule, which counts a listed product with no published certificate as zero in the lab average. Certificates cover 35 of the 36 products we list that the vendor offers for sale. Lab 7.6 to 7.4.

373. October 21, 2026BulkGLPDown 8.37 → 7.44 (-0.93)

     Lab 8.1 to 6.4. Recomputed under our published rule, which averages the lab score over the products we list and counts a listed product with no certificate as zero. The Freedom Diagnostics certificates were read firsthand, not confirmed at the laboratory, apart from one ARA-290 report that we confirmed on the laboratory's site and that shows 53.90% purity. We hold no certificate for the BPC-157/TB-500 blend. The 23 July 2026 entry now says the certificates were read firsthand.

374. October 21, 2026Core PeptidesUp 6.28 → 6.61 (+0.33)

     Lab 5.8 to 6.4. Recomputed under our published rule, which averages the lab score over the products we list and counts a listed product with no certificate as zero. Thirteen of 17 listed products carry Vanguard Laboratory reports listed under Core Peptides' name; the document shown for Fragment 176-191 is the AOD-9604 analysis, so that product now counts as having no certificate. A small deduction applies because the site says every product is tested before release while four listed products have no certificate of their own.

375. October 21, 2026GenX BioDown 6.19 → 4.57 (-1.62)

     Lab 3.75 to 0.8. Recomputed under our published rule, which averages the lab score over the products we list and counts a listed product with no certificate as zero: certificates were found for 7 of the 34 products we list, none carries a key we could check, and all are more than 12 months old. One of the seven, for BPC-157, names no laboratory.

376. October 21, 2026Hello StacksUp 6.12 → 6.54 (+0.42)

     Pricing 5.2 to 8.0. The earlier figure blended the pen line with the vials. Our method everywhere else uses standard prices for the cheapest plain vial of each compound, with no code applied; on that basis the plain vials sit at about 0.87 times the market median per milligram, with 26 of 32 compounds below the median.

377. October 21, 2026Honest PeptideDown 8.03 → 6.88 (-1.15)

     Lab 8.5 to 6.4. Recomputed under our published rule, which averages the lab score over the products we list and counts a listed product with no certificate as zero. The certificates name Freedom Diagnostics, Janoshik and Chromate, but none has been confirmed at the issuing laboratory: the keys we had stored on the Freedom rows belong to separate Janoshik heavy-metals reports, and the Freedom search codes are not yet recorded. Two certificates are more than 12 months old, and two blend certificates have not been read.

378. October 21, 2026JD BioWorksUp 7.05 → 7.71 (+0.66)

     Lab 7.5 to 8.7. The earlier 7.5 had no recorded arithmetic. Recomputed under our published rule, which averages the lab score over the products we list and counts a listed product with no certificate as zero: all 17 listed products carry ILS Laboratories certificates confirmed at the laboratory's portal, from a laboratory that states ISO/IEC 17025 accreditation, with no endotoxin or sterility testing. A small deduction applies because the same lot labels appear on certificates for different compounds.

379. October 21, 2026Limitless BiotechDown 7.46 → 7.29 (-0.17)

     Tenure 10 to 6.5. The company states it has operated since 2020, about six years, which falls below the top band reserved for businesses over ten years. Lab and the other subscores are unchanged.

380. October 21, 2026Medura PeptidesDown 3.08 → 2.80 (-0.28)

     Lab 0.5 to 0 and tenure 2.2 to 2.0. No product we list has a certificate, and under our published rule the lab score is zero rather than a small floor. Tenure was aligned to the domain, registered in April 2026.

381. October 21, 2026Modern AminosDown 8.13 → 7.98 (-0.15)

     Tenure 8.5 to 5.5. The domain was registered in November 2022, about four years ago, so the operating-history score was moved from the five-to-ten-year band to the band for its age. Three Kovera rows that showed a laboratory check were corrected, because no check through Kovera's lookup is recorded. The lab score is unchanged pending a re-audit.

382. October 21, 2026Modified AminosDown 7.65 → 6.44 (-1.21)

     Lab 7.5 to 5.3. The earlier lab score averaged only the 21 listed products that have a certificate. Four products we list (MT-2, Sermorelin, NAD+ and Cagrilintide) had no certificate in the vendor's library, and under our rule they count as zero. The public notes were also corrected: no certificate we read covers the seven analyses the vendor advertises.

383. October 21, 2026Oasis LabsDown 6.78 → 6.69 (-0.09)

     Tenure 5 to 3.2. The domain was registered in November 2024, about 23 months ago, and nothing on record supports an earlier start, so the operating-history score was aligned to that age. The public notes were rewritten to include the July 2026 findings.

384. October 21, 2026OMNI PeptidesDown 6.38 → 5.77 (-0.61)

     Lab evidence re-checked on 20 October 2026 under our coverage rule, which counts a listed product with no published certificate as zero in the lab average. Certificates cover 12 of the 17 products we list that the vendor offers for sale. Lab 7.0 to 5.9.

385. October 21, 2026Paramount PeptidesDown 6.04 → 5.16 (-0.88)

     Lab 5.0 to 3.4. Recomputed under our published rule, which averages the lab score over the products we list and counts a listed product with no certificate as zero. The certificates in our archive have not been confirmed with the issuing laboratory, all are more than 12 months old, several listed products have no certificate, and the BPC-157 certificate reports BPC-157 as not detected. The 8 October 2026 entry described the archived certificates as verified; they are Janoshik-format reports in the vendor's name that we could not check with Janoshik.

386. October 21, 2026PepBioticsDown 1.85 → 1.57 (-0.28)

     Lab 0.5 to 0. Every published certificate is a self-declared specimen rather than a laboratory report, so no product we list has a certificate, and under our published rule the lab score is zero rather than a small floor.

387. October 21, 2026Peptara LabsDown 2.29 → 1.85 (-0.44)

     Lab 0.8 to 0. The certificates contain features we could not reconcile with measured laboratory results and carry no laboratory lookup, so they are treated as no independent certificate, and three listed products have no certificate at all. Under our published rule the lab score is zero.

388. October 21, 2026Peptide LabsDown 3.50 → 3.29 (-0.21)

     Lab 2.0 to 1.6, correcting the 18 October 2026 figure. Four of the 19 products we list carry their own Kovera certificate, confirmed at the laboratory; three score 8 and tesamorelin 6.5 under our rubric, and the other 15 count as zero, which gives 1.6.

389. October 21, 2026Peptide.ExpressDown 4.50 → 3.51 (-0.99)

     Lab 3.5 to 1.7. Recomputed under our published rule, which averages the lab score over the products we list and counts a listed product with no certificate as zero: certificates verified at the laboratory cover 2 of the 20 products we list, six rest on a laboratory we could not establish as independent, and twelve have none.

390. October 21, 2026Peptides SourceUp 7.38 → 7.75 (+0.37)

     Lab evidence re-checked on 20 October 2026 under our coverage rule, which counts a listed product with no published certificate as zero in the lab average. Certificates cover 26 of the 26 products we list that the vendor offers for sale. Lab 7.1 to 7.8.

391. October 21, 2026Peptides SourceDown 7.49 → 7.38 (-0.11)

     Tenure 5.9 to 3.6. The domain was registered in February 2024, about two and a half years ago, and no founding year is stated, so the operating-history score was aligned to the domain age. The public notes were also rewritten to match the July 2026 audit; the lab score is unchanged.

392. October 21, 2026PepVialDown 2.13 → 1.85 (-0.28)

     Lab 0.5 to 0. No product we list has a certificate, and under our published rule the lab score is zero rather than a small floor.

393. October 21, 2026Prime Lab PeptidesUp 5.87 → 6.63 (+0.76)

     Lab 5.5 to 6.9. The 18 October 2026 lab score averaged the whole catalogue of about 40 products, while every other vendor is scored over the products we list. Recomputed over the six products we list: three Freedom Diagnostics reports confirmed at the laboratory, two Freedom-named image certificates and one Janoshik report from 2025, with the same deductions for same-lot inconsistencies and the accreditation claim.

394. October 21, 2026PSPeptidesDown 3.97 → 3.15 (-0.82)

     Lab 2.0 to 0.5, correcting the arithmetic behind the 18 October 2026 figure. Only the retatrutide certificates, from Vanguard Laboratory, are independent evidence; the North American Diagnostics documents carry no weight, as our notes say, but the earlier calculation still gave them about a point each.

395. October 21, 2026Raw AminoDown 6.71 → 5.89 (-0.82)

     Lab 6.0 to 4.5. Recomputed under our published rule, which averages the lab score over the products we list and counts a listed product with no certificate as zero. Fifteen products carry MZ Biolabs certificates with no key we could check, the AOD-9604 certificate is issued by the vendor itself, Fragment 176-191 has none, and most MZ certificates carry the same lot date across different compounds. A BPC-157 row that showed a laboratory check was corrected: the stored value was the lot date.

396. October 21, 2026Southern AminosUp 7.04 → 7.81 (+0.77)

     Full certificate library re-checked on 21 October 2026: all 205 files in the library were read and 189 certificate codes were checked against Freedom Diagnostics and ILS Laboratories records, of which 186 matched. Certificates cover 30 of the 31 products we list, most with multi-vial panels including endotoxin and sterility screening. Lab 7.4 to 8.8.

397. October 21, 2026Swiss ChemsDown 6.16 → 4.99 (-1.17)

     Lab 4.8 to 2.8 and tenure 10 to 8.5. We re-read the certificates behind each listed product under our published rule, which averages the lab score over the products we list and counts a listed product with no certificate as zero. Six products carry Freedom Diagnostics reports confirmed on the laboratory's own site, several carry Janoshik reports we could not check there or vendor documents naming no laboratory, and 16 of the 33 products we list have no certificate. Tenure was aligned to the company's 2018 start, about eight and a half years ago, rather than the top band for businesses over ten years.

398. October 21, 2026Thrive PeptidesUp 6.29 → 7.72 (+1.43)

     Lab 5.5 to 8.1. All nine Freedom Diagnostics certificates we hold for the products we list resolve on the laboratory's own site by their printed search codes, each naming Thrive Peptides as the client, including newer June 2026 lots for BPC-157, GHK-Cu and Semax. The earlier figure had counted five of them as unreadable images. The panels cover identity and purity only.

399. October 21, 2026Transition BiotechUp 6.94 → 7.60 (+0.66)

     Lab 7.5 to 8.7. The earlier 7.5 deducted for Kovera's undisclosed accreditation, which our rubric already accounts for, and for a single testing round, which is not a rubric adjustment. Recomputed under our published rule, which averages the lab score over the products we list and counts a listed product with no certificate as zero: all ten listed products carry Kovera certificates confirmed at the laboratory with endotoxin and heavy-metals results. The microbial result is a rapid screen, so it is no longer credited as a sterility test.

400. October 21, 2026Verified PeptidesDown 8.44 → 8.11 (-0.33)

     Lab 7.6 to 7.0. The July 2026 rise to 7.6 treated the Janoshik keys as checkable at the laboratory, but Janoshik's lookup was not available to us and no report was confirmed there. The reports still print keys and most products also have an endotoxin report; two reports date from mid 2025. Six listing rows that showed sterility testing were corrected, because no sterility testing appears.

401. October 21, 2026Vyal LabsDown 6.18 → 4.86 (-1.32)

     Lab 6.5 to 4.1 and third-party testing status from verified to not independently verified. Nine of the 26 products we list have no certificate, which our listings had wrongly shown as covered, and under our rule they count as zero. None of the 17 certificates can be confirmed with the laboratory, whose verification link leads to its home page, so the testing status no longer reads as verified.

402. October 21, 2026YourFitnessPeptidesDown 2.52 → 2.00 (-0.52)

     Lab 0.8 to 0 and tenure 3.0 to 1.5. No product we list has a certificate, and under our published rule a product with no certificate scores zero, so the lab score is now zero rather than a small floor. Tenure was aligned to the domain age.

403. October 20, 2026Apollo Peptide SciencesUp 4.67 → 6.50 (+1.83)

     Lab evidence re-checked on 20 October 2026 under our coverage rule, which counts a listed product with no published certificate as zero in the lab average. Certificates cover 9 of the 9 products we list that the vendor offers for sale. Lab 2.5 to 6.2. A page-by-page re-check found a Janoshik report on all nine listed products, correcting the earlier October finding that seven had been removed; transparency 3.0 to 4.5. The score remains under the third-party cap because the reports could not be confirmed with the laboratory.

404. October 20, 2026Arctic Lab SupplyDown 8.03 → 6.11 (-1.92)

     Lab evidence re-checked on 20 October 2026 under our coverage rule, which counts a listed product with no published certificate as zero in the lab average. Certificates cover 8 of the 17 products we list that the vendor offers for sale. Lab 7.9 to 4.4.

405. October 20, 2026Azyrion LabsUp 4.58 → 5.68 (+1.10)

     Lab evidence re-checked on 20 October 2026 under our coverage rule, which counts a listed product with no published certificate as zero in the lab average. Certificates cover 23 of the 25 products we list that the vendor offers for sale. Lab 5.0 to 7.0.

406. October 20, 2026DAAVY ResearchFirst published at 7.01

     lab 7.0 / shipping 8.0 / pricing 8.7 / tenure 0.6 / transparency 4.5. Lab 7.0: every one of the 15 products and every size has a Bioviridian certificate naming DAAVY as the client, all 21 were confirmed at the laboratory's own site and 18 match byte for byte, with purity of 99.64% or higher; held back by the absence of endotoxin or sterility testing, a laboratory with no ISO/IEC 17025 accreditation on our record, four certificates without lot numbers, and a 500 mg 5-Amino-1MQ report whose laboratory copy shows about 456 mg while the vendor's copy and product page show 507 mg. The laboratory's principal chemist also reviews the vendor's educational content, which a reader may weigh. Shipping 8.0: next-business-day UPS dispatch with tracking, a 30-day return window for unopened items, free replacement of lost, damaged or wrong orders, and card payment; every order is manually reviewed first and support is by email only. Pricing 8.7: below the market median on all 14 compared products, less a small deduction because each is displayed against a higher struck-through comparison price. Tenure 0.6: the domain is about two months old and the company was formed in July 2026. Transparency 4.5: a named Texas LLC with a verifiable filing number and dated policies, offset by a business-centre registered office, a different mailbox address on state tax records, no phone, no named owner, no governing-law clause and code-named GLP-1 products.

407. October 20, 2026Drexa LabsDown 7.11 → 4.09 (-3.02)

     Lab evidence re-checked on 20 October 2026 under our coverage rule, which counts a listed product with no published certificate as zero in the lab average. Certificates cover 4 of the 32 products we list that the vendor offers for sale. Lab 6.6 to 1.1.

     Lab evidence re-checked on 20 October 2026 under our coverage rule, which counts a listed product with no published certificate as zero in the lab average. Certificates cover 31 of the 46 products we list that the vendor offers for sale. Lab 8.2 to 5.1.

413. October 20, 2026Peptix USAUp 7.05 → 7.33 (+0.28)

     Second vendor-requested reassessment, verified on the live site the same evening. Lab rises from 7.2 to 7.4: the quality page now states which laboratory tests which product and what each panel covers, the retatrutide Freedom Diagnostics report is labelled as Freedom's, the tesamorelin date matches the ILS record, and the certificates still match the laboratories. The about, FAQ and research pages still describe every batch as tested by accredited laboratories, which the Freedom reports are not. Shipping rises from 7.0 to 7.8: sealed returns within seven days now get a free return label, damage, loss and theft share one seven-day claim window, and the weekday same-day cutoff is stated consistently. Transparency rises from 4.8 to 5.0: the dosage calculator and the trial results on product pages are gone, but 26 dosage and protocol articles quoting clinical dosing and reconstitution concentrations remain, and no operating company or address is published.

414. October 20, 2026Peptix USAUp 6.61 → 7.05 (+0.44)

     Vendor-requested reassessment, verified on the live site. Lab rises from 6.8 to 7.2: tesamorelin now carries an ILS Laboratories full-panel certificate, confirmed on the laboratory's portal, so every product has lab-verified testing; the quality page still overstates the testing. Shipping rises from 6.0 to 7.0: the returns policy now matches the homepage, reshipping lost, damaged or stolen parcels at no cost. Transparency rises from 4.5 to 4.8: the terms carry a current date and trial results are cited as literature, but no operating company or address is published and the dosage calculator remains.

415. October 20, 2026Pinnacle Peptide LabsUp 6.50 → 6.69 (+0.19)

     Lab evidence re-checked on 20 October 2026 under our coverage rule, which counts a listed product with no published certificate as zero in the lab average. Certificates cover 11 of the 13 products we list that the vendor offers for sale. Lab 7.4 to 6.3. The site is back online and its certificates name Pinnacle as the client at the laboratory, so the offline adjustment of 8 October is reversed.

416. October 20, 2026Prime Peptide SolutionsDown 6.60 → 5.50 (-1.10)

     Lab evidence re-checked on 20 October 2026 under our coverage rule, which counts a listed product with no published certificate as zero in the lab average. Certificates cover 10 of the 20 products we list that the vendor offers for sale. Lab 6.3 to 4.3.

     lab 1.0 / shipping 5.0 / pricing 8.0 / tenure 1.0 / transparency 2.5.

419. October 20, 2026Redline Bio LabsFirst published at 3.95

     lab 2.5 / shipping 5.5 / pricing 8.0 / tenure 1.0 / transparency 4.5. Lab 2.5: six Freedom Diagnostics certificates verified at the laboratory and one BTLabs report are the only independent evidence we could establish; most certificates come from SteriGenix Analytical, which we could not establish as an independent operating laboratory, ten AV Analytics certificates issued on 18 October did not appear in that laboratory's lookup on 20 October, thirteen of 48 matched products carry no report, one retatrutide report shows about half the label claim passed, and the bacteriostatic water certificate prints a batch number that the laboratory's lookup assigns to a separate report for a different client, with the same purity and benzyl alcohol results. Shipping 5.5: same-day UPS Ground dispatch with tracking and a free-shipping threshold, offset by final sales, a preselected paid protection add-on that decides lost-parcel reshipment, and a card surcharge. Pricing 8.0: below the market median on 36 of 48 compared products. Tenure 1.0: the domain is about six months old. Transparency 4.5: a named LLC and a private-mailbox address are published, but no phone number, named people or governing state.

420. October 20, 2026Spartan PeptidesDown 5.26 → 3.39 (-1.87)

     Lab evidence re-checked on 20 October 2026 under our coverage rule, which counts a listed product with no published certificate as zero in the lab average. Certificates cover 4 of the 13 products we list that the vendor offers for sale. Lab 5.0 to 1.6.

421. October 20, 2026Zeptix LabsDown 7.89 → 6.74 (-1.15)

     Lab evidence re-checked on 20 October 2026 under our coverage rule, which counts a listed product with no published certificate as zero in the lab average. Certificates cover 11 of the 14 products we list that the vendor offers for sale. Lab 8.3 to 6.2.

422. October 18, 2026Amino AmigosDown 6.10 → 4.37 (-1.73)

     Re-audited 2026-10-18; the May 2026 score was a seed estimate. Lab falls from 4.46 to 2.8: the certificates do name their laboratories (Janoshik, MZ Biolabs, Analiza Bialek, TrustPointe), correcting the earlier note that no lab was disclosed, but the newest is about 14 months old, most are about two years old, none could be confirmed at a laboratory, and several product pages show no certificate or the wrong one. Shipping falls from 8.5 to 6.0: free tracked USPS shipping and a 30-day unused-return policy are confirmed, but loss and damage are handled case by case and checkout offered bank payment only. Pricing moves from 9.5 to 8.0 on 21 live standard prices about 11% below the market median. Tenure moves from 5.9 to 4.5 on a domain registered in March 2023. Transparency moves from 4.6 to 4.0: an address and phone are published, but no operating company is named.

423. October 18, 2026Biotech PeptidesUp 4.11 → 5.52 (+1.41)

     Re-audited 2026-10-18, replacing a May 2026 seed score that was never properly audited. Lab rises from 0.4 to 4.5 and the testing status moves from unverified to third-party tested: 14 of 21 tracked products now show July 2026 MZ Biolabs reports, though only the BPC-157 report was confirmed in the laboratory's certificate viewer, most show lot numbers that differ from the laboratory's own link, and five products still rely on vendor-issued documents. Shipping eases from 8.5 to 7.0 because returns are refused and the refund promise has no stated terms, while the free replacement of lost or damaged parcels holds it up. Pricing falls from 9.5 to 7.2 on live prices near the market median. Tenure falls from 9.0 to 6.8 for a domain registered in January 2020. Transparency falls from 5.9 to 4.5: no legal entity is named and the stated governing law does not match the listed address. Semax and Selank are now recorded as carried.

424. October 18, 2026Cernum BiosciencesUp 2.05 → 3.65 (+1.60)

     Re-audited on 2026-10-18. The second set of images on each product page, labeled as third-party tests and not assessed in May, was read in full: they are Janoshik Analytical reports ordered by the Chinese manufacturer on its own material, with no batch identified, rather than tests of Cernum's stock. Lab moves from 0 to 3.0 to credit that supplier testing, while testing of Cernum's own lots remains unestablished, so the third-party gate still applies. Pricing eases from 7.9 to 7.6 on a fresh comparison of 20 products about a fifth above the market median. Shipping, tenure and transparency are unchanged: no returns, discretionary refunds, and no company or address published.

425. October 18, 2026Core PeptidesUp 3.11 → 6.28 (+3.17)

     Re-audited 2026-10-18, replacing a May 2026 seed score that was never properly audited. Lab rises from 0 to 5.8 and testing status moves from not tested to third-party tested: 14 of 17 tracked products now link Vanguard Laboratory reports, and the reports we checked are listed in Vanguard's own reporting hub, though the panels cover purity and identity only, and the Fragment 176-191 report repeats the AOD-9604 analysis. Shipping rises from 5.9 to 7.0 for a clear dispatch table, card payment and a 30-day refund window. Pricing falls from 8.5 to 7.6 on live standard prices near the market median. Tenure moves from 8.5 to 7.0 for a domain registered in October 2019. Transparency eases from 4.6 to 4.0: an Orlando suite address and phone, but no legal entity or governing law. Semaglutide, tirzepatide and retatrutide remain unlisted.

426. October 18, 2026Direct PeptidesUp 4.87 → 7.50 (+2.63)

     Re-audited on 2026-10-18 from the live site and the issuing laboratories. Lab rises from 4.85 to 7.8: the May review found no per-product certificates, while every product now links a current certificate and nearly all Horizon Analytical reports were confirmed on the laboratory's own portal, with accredited full-panel reports for two products. Shipping rises from 5.9 to 8.0 on a published same-day cutoff, tracked USPS shipping, damage and loss replacement and a return route for unopened items, held back by contradictory wording in the general terms. Pricing rises from 4.6 to 8.3 because standard prices now sit at the market median across 33 compounds. Tenure eases from 3.3 to 2.8 because the current store dates from 2025 even though the domain is older. Transparency rises from 3.3 to 4.5 for the verifiable certificate library and a published mailing address, still limited by the absence of a named operating company. Note added 22 October 2026: the two full-panel reports are from Vanguard Laboratory; Vanguard Laboratory's A2LA accreditation does not cover peptide testing, so it is not counted as accredited (check L6).

427. October 18, 2026Felix Chemical SupplyUp 2.73 → 7.09 (+4.36)

     First full audit, read through a customer account because the whole site requires registration; the May score was a placeholder. Lab rises from 0.5 to 8.0 and testing is now counted as third-party: the newest certificate for each tracked product was checked, and all but one of the Freedom Diagnostics reports resolve at the laboratory with matching results and endotoxin testing, plus a verified ILS full panel for retatrutide. Shipping rises from 4.6 to 6.0 (FedEx two-day, same-day dispatch, but parcel protection only as a paid add-on and no refund policy). Pricing rises from 7.2 to 8.2 on live prices slightly below the market. Tenure falls from 5.9 to 2.8: the domain dates from April 2025, not 2012 as the May record stated. Transparency falls from 3.3 to 2.5: no company or address is published.

428. October 18, 2026Loti LabsDown 7.49 → 7.22 (-0.27)

     Re-audited 2026-10-18 from the live site and the laboratories' own hosts; the May 2026 score was a seed estimate. Lab rises from 6.5 to 7.3: the earlier note said the testing lab was not named, but every current certificate names Bioviridian or SR Biolabs and 24 of 31 match the laboratories' hosted copies, most newer ones with endotoxin screens; the score is held back by seven posted copies that differ from the laboratory's records (one doubled content figure, and six with lot numbers the lab copies lack and later issue dates than those copies), plus a product page linking a certificate for a different blend, a GHRP-6 report with GHRP-2's mass, and no sterility testing. Shipping falls from 10 to 7.0: same-day dispatch, cards and a 30-day unopened return policy are confirmed, but loss and damage are covered only by a paid add-on and the policy treats chargebacks as a breach of its terms. Pricing moves from 7.2 to 8.0 on 22 live standard prices near the market median. Tenure falls from 10 to 7.0: the domain was registered in June 2019, and the site's claim of 14 or more years is not corroborated. Transparency falls from 6.6 to 5.0: no legal entity is named and the address is a suite number.

429. October 18, 2026NuScience PeptidesDown 7.13 → 6.54 (-0.59)

     Re-audited 2026-10-18 from the live site. Lab 7.12 to 7.2: 36 Freedom Diagnostics and Chromate reports confirmed at the laboratories, with 34 posted files identical to the laboratory copies, offset by two image-only certificates that could not be matched, a 2024 cagrilintide report and limited endotoxin coverage; this replaces the May 2026 statement that the vendor published no certificates. Shipping 8.5 to 5.5: all sales are final and the terms disclaim responsibility for lost or damaged parcels when insurance is declined. Pricing 8.5 to 7.7: standard list prices measured at about 1.12 times the market median, and every product is shown at a markdown from a higher struck-through list price; a small deduction because the markdown is permanent. Tenure 3.3 to 4.0: the domain was registered in May 2023 and the earliest posted certificate is from July 2024. Transparency 1.5 to 2.5: phone, email, city and a public certificate library are given, but no operating company or street address appears on the site, and the FDA issued a warning letter on 24 August 2026. The products named in that letter have been removed from the catalog. Note added 22 October 2026: the deduction for a permanent markdown was withdrawn on 22 October 2026; a standing sale price now counts as the price.

430. October 18, 2026Onyx BiolabsDown 7.30 → 7.12 (-0.18)

     Re-audit, read through a customer account because the catalog, prices, certificates and policies are now behind registration. Lab rises from 7.23 to 7.8: 75 of 76 Kovera reports were verified in the laboratory's records, covering nearly every product, many with endotoxin and heavy-metal screens; there is no sterility testing and the AOD-9604 entry could not be verified. Shipping falls from 7.2 to 5.5 because all sales are final, the damage window is 48 hours, and lost or misdelivered parcels are covered only with paid insurance. Pricing moves from 9.5 to 8.6 on live selling prices about 22% below the market, with a small deduction because every product is shown against a struck-through regular price. Tenure 2.0 to 2.3 and transparency 7.2 to 6.5: the operating company and address are named, but the catalog and certificates are no longer public.

431. October 18, 2026Peptide LabsUp 3.11 → 3.50 (+0.39)

     Re-audit, read through a customer account because the whole catalog is now behind registration. Lab rises from 0 to 2.0 and testing is now counted as third-party: eight Kovera reports from May 2026 were verified at the laboratory, but they cover a small part of a catalog of more than sixty products, and one blend report is presented for standalone BPC-157 and TB-500. Shipping falls from 7.2 to 5.5 (no refunds or returns). Pricing falls from 8.5 to 7.3 on live prices near the market median. Tenure falls from 3.3 to 2.2 (domain registered August 2025). Transparency falls from 4.6 to 2.0: no company or address is published.

432. October 18, 2026Peptide ProsDown 6.54 → 3.78 (-2.76)

     Re-audited 2026-10-18; the May 2026 score was a seed estimate. Lab falls from 4.89 to 1.5: every published certificate is a MZ Biolabs report dated 2021 to 2023 with no verification route, about six of 27 carried peptides have one, and the claim of HPLC testing on every batch is not supported. Shipping falls from 8.5 to 5.5: free reshipment of lost parcels is confirmed, but all sales are final and there is no card payment. Pricing moves from 9.5 to 7.7: list prices are about a third above the market median, while the standing site-wide reduction brings them about 5% below it; the score is reduced slightly because every product is shown as permanently marked down from a struck-through price. Tenure moves from 10 to 9.0 on a domain registered in February 2014. Transparency moves from 4.6 to 5.0: the operating LLC, a phone line and a Miami Beach suite address are published.

433. October 18, 2026Peptix USAFirst published at 6.59

     lab 6.8 / shipping 6.0 / pricing 9.0 / tenure 2.0 / transparency 4.0.

434. October 18, 2026Prime Lab PeptidesDown 7.85 → 5.87 (-1.98)

     Re-audited 2026-10-18 against the July 2026 score. Lab 7.9 to 5.5: the catalogue has grown from about eight GLP-1 products to about 40, and only the seven February 2026 Freedom Diagnostics reports could be confirmed at the laboratory; the newer certificates are images with no code we could check, several show same-lot inconsistencies, and none covers endotoxin. Shipping 8.5 to 7.0: free shipping and card payment remain, but standard service is now FedEx 3-Day and nothing is refundable once shipped. Pricing 8.0 to 7.6: live prices sit at about the market median. Tenure 4.0 to 2.5: the domain dates from March 2025, and the July figure leaned on review volume. Transparency 8.0 to 3.5: the footer review rating comes from a site run by the vendor's own operators, the 'over 12 years' claim conflicts with the domain age, the address has changed, and a sister company in a UAE free zone is listed.

435. October 18, 2026Prime Peptide SolutionsUp 6.42 → 6.60 (+0.18)

     Correction. The initial audit stated that the certificate library listed the wrong purity for the seven older Kovera batches. That was our error: the library and every batch page show Kovera's own figures. Lab rises from 6.0 to 6.3 and transparency from 6.0 to 6.5. Coverage (about ten of twenty-eight compounds) and the absence of endotoxin and sterility testing still limit the lab score.

437. October 18, 2026Prime PeptidesUp 7.00 → 7.62 (+0.62)

     Re-audited 2026-10-18 from the live site, replacing the May 2026 seed score, which was based on cached snippets because the site then blocked us. Lab 6.96 to 8.0: 17 Freedom Diagnostics certificates with endotoxin testing were found at the laboratory (16 vendor files opened and matched), and three Kovera reports and four Bioviridian reports all matched at the laboratories, held back by about half the catalogue relying on Janoshik reports we cannot check. Shipping stays at 8.5: weekday FedEx 2-Day Air and 30-day returns on unopened items with a prepaid label. Pricing 8.5 to 7.2: live standard prices measured at about the market median. Tenure 2.0 to 3.7: the domain dates from January 2024. Transparency 2.0 to 5.0: the operator, addresses, phone and governing law are now published, weighed against the December 2024 FDA warning letter over products it still sells and a coded name for tirzepatide.

438. October 18, 2026Profound AminosUp 6.39 → 6.66 (+0.27)

     Re-audited 2026-10-18 from the live site, replacing the May 2026 seed score. Lab 6.54 to 7.4: the certificate library is public, current and drawn from several laboratories, and we confirmed 152 certificates at Freedom Diagnostics, TrustPointe, Chromate and Zyntro; it is held back by the absence of endotoxin testing, nine Freedom reports not found at the laboratory, cap-colour rather than batch traceability and three products resting on 2025 reports. Shipping 7.9 to 5.0: no returns, refunds only against an outside lab result, a ten-day wait on lost parcels and peer-to-peer payment without buyer protection. Pricing 5.9 to 8.1: the full catalogue is now publicly priced and runs about 16% below the market median. Tenure 3.3 to 3.5 for a domain a little over two years old. Transparency 3.3 to 4.0: a mailing address, phone line and public certificate library, against no legal entity, no named people and coded GLP-1 names.

439. October 18, 2026Protide HealthDown 7.81 → 7.14 (-0.67)

     Re-audited 2026-10-18 from the live site, replacing a May 2026 seed score that was never properly audited. Lab rises from 7.0 to 8.4: all 22 tracked products now carry current Freedom Diagnostics reports, each confirmed at the laboratory, most with endotoxin, microbial, heavy-metal and fentanyl panels. Shipping falls from 8.5 to 5.0 because the published policy makes every sale final, places lost-parcel claims on the buyer and limits damage claims to seven days. Pricing falls from 9.5 to 7.2 on live standard prices that sit above the market median for most products. Tenure falls from 7.2 to 2.8 because the domain dates from January 2025. Transparency falls from 9.5 to 6.0: a named Delaware corporation, address and phone, but no named people. Tirzepatide is now recorded as carried under the GLP-2 code name.

440. October 18, 2026PSPeptidesDown 6.97 → 3.97 (-3.00)

     Re-audited 18 October 2026, replacing the 7 July 2026 review. Lab fell from 7.0 to 2.0. The July score treated North American Diagnostics as a real third-party lab. This audit found that its website carries the same mail-account ownership token as the vendor's domain and shares its, registrar and nameservers with the vendor's domain, that 781 of its 796 published reports name this vendor, that its sterility results were issued too quickly for the method they cite, and that four report sets are dated after their own publication. Only the retatrutide certificates, from Vanguard Laboratory, whose ISO/IEC 17025 scope does not cover peptide testing, were confirmed at an independent laboratory. Shipping moved from 7.2 to 6.8: shipping is fast and cards are accepted, but claim windows are short, packed orders cannot be cancelled, and buying requires an account. Pricing moved from 8.2 to 8.3 on a fresh read of 45 products. Tenure fell from 2.8 to 1.8 because the domain is under a year old. Transparency fell from 6.2 to 3.5: the site names no company, address or staff, its stated founding year conflicts with its domain records, and its own pages give conflicting answers on phone support. Note added 22 October 2026: Vanguard Laboratory's A2LA accreditation does not cover peptide testing, so it is not counted as accredited (check L6).

441. October 18, 2026Pure Health PeptidesDown 7.85 → 6.50 (-1.35)

     Site offline. purehealthpeptides.com no longer serves a store: the domain resolves to a local address on every resolver we checked, and the registry shows a transfer pending since October 14. Testing is treated as unverified while nothing can be checked, which applies the third-party cap. Subscores earned earlier were left as they were; the outage does not make that evidence false, and the review will be re-audited when the site returns.

442. October 18, 2026Research Peptides LabUp 5.66 → 6.14 (+0.48)

     Re-audit, read through a customer account because the catalog and certificate library are now behind registration. Lab rises from 5.17 to 6.5: all 23 Freedom Diagnostics certificates were verified at the laboratory, covering nearly the whole catalog, but they are identity and purity only, 9 to 12 months old, carry chemical registry numbers instead of batch codes, and the three below 99% are not shown on their product pages. Shipping falls from 7.2 to 5.8 because the 60-day money-back guarantee credited in May is gone and damage must be reported within 24 hours. Pricing rises from 7.2 to 7.8 on live standard prices about 17% above the market median. Tenure 2.0 to 2.2. Transparency falls from 4.0 to 2.5: no company, address or phone is published.

443. October 18, 2026Sports Technology LabsDown 6.83 → 6.01 (-0.82)

     Re-audited 2026-10-18, replacing a May 2026 seed score that was never properly audited. Lab rises from 5.3 to 5.8: every tracked peptide now has an MZ Biolabs report, most refreshed in 2026, and newer reports link to the laboratory's own site, where the BPC-157 report was confirmed; five reports date from October 2025. Shipping falls from 9.0 to 7.0 because the terms disclaim responsibility for lost shipments and offer no reship policy, while the 60-day money-back guarantee holds it up. Pricing falls from 8.5 to 5.5 because standard prices sit well above the market median. Tenure moves from 8.5 to 7.0 for a domain registered in August 2019. Transparency falls from 7.9 to 5.0: an address and phone, but no legal entity, governing law or named people. Semax is now recorded as carried.

     Correction: our earlier note that three of the seven verification links on the vendor's site were cut short was wrong; the site links all seven in full, and the truncation was in our own checking. That note did not affect the score and has been removed. Separately, the vendor added a US delivery guarantee that refunds shipping if delivery runs late, so shipping rose 8.5 to 9.0.

451. October 14, 2026JD BioWorksDown 7.12 → 7.05 (-0.07)

     Catalog refreshed at the vendor's request: regular prices rose on most non-GLP products and five products were added. All five new certificates verified at ILS. Lab, shipping, tenure and transparency unchanged.

461. October 8, 2026Apollo Peptide SciencesDown 7.70 → 4.67 (-3.03)

     Seven of the eight product pages that carried a test report in July no longer do. One report remains, for IGF-1 LR3, and it could not be confirmed with the laboratory because that laboratory's public verification portal is closed to automated checks. The site still advertises third-party testing and still says readers can see the COAs, which is now a dead pointer.

462. October 8, 2026Arctic Lab SupplyUp 7.42 → 7.93 (+0.51)

     Vendor disputed three points. Shipping and processing upheld in their favour because the policy changed: free US shipping above an order minimum with no membership and a 24-hour dispatch commitment replaced membership-gated free shipping and no stated processing time, so shipping rose 7.0 to 8.5. The verification-link finding was not upheld; investigating it confirmed all seven certificates at the laboratory, so lab rose 7.6 to 7.9. Transparency rose 7.0 to 7.8 for the dated public corrections log.

463. October 8, 2026NextGen PepsUp 6.90 → 7.12 (+0.22)

     Bioviridian added to the laboratory roster after verifying certificate COA9754 at the laboratory's own portal and confirming the vendor's published PDF is byte-identical to the laboratory's. 21 Bioviridian certificates dated 2026-09-25, carrying endotoxin testing under USP <85>.

464. October 8, 2026Paramount PeptidesUp 3.29 → 6.04 (+2.75)

     The lab score of zero was structural, set when certificates sat behind an email and passcode wall. That wall is gone and the lookup now takes a lot number. Certificates verified from our own archive are genuine Janoshik reports naming Paramount as client and manufacturer. Held at 5.0 because the documents are from June 2025, a certificate cannot be seen before purchase, no lab is named publicly, and the panel has no endotoxin, sterility or heavy metals. Separately recorded: their BPC-157 certificate reports BPC-157 not detected and acetylated BPC-157 in its place.

465. October 8, 2026Pinnacle Peptide LabsDown 7.29 → 6.50 (-0.79)

     pinnaclepeptidelabs.com no longer resolves, confirmed from four independent paths while controls resolved normally. thirdPartyTested moved to null because nothing can be verified while the site is down, which applies the gate. Promos removed and the affiliate link suspended so no reader is sent to a dead address. Subscores earned in July were left intact; the outage does not make that evidence false.

466. October 8, 2026Zeptix LabsUp 7.73 → 7.89 (+0.16)

     Four certificates dated 2026-10-07 verified first-hand at Freedom Diagnostics for GLP-3 R 10mg and 30mg, Tesamorelin 10mg and MOTS-c 10mg, each adding heavy metals by ICP-MS and a fentanyl screen. MOTS-c and Tesamorelin also moved from Accumark to Freedom Diagnostics. The vendor describes these as nine analyses; seven are present, with sterility, conformity and pH absent.

469. October 7, 2026Hacker PeptidesUp 6.33 → 6.43 (+0.10)

     PSR withdrew its most serious finding after the owner disputed it and turned out to be right. We had reported that Quantum-332 Elite contained about 2 micrograms of SLU-PP-332. The laboratory's own record reads 2.021mg and 1.985mg; the copy published on the vendor's site carries a microgram unit in error. Injection pens and cartridges were also verified removed from the catalogue in the same period.

474. October 4, 2026Transition BiotechUp 6.50 → 6.90 (+0.40)

     Vendor-requested catalog refresh, verified against the live site. Pricing rose from 6.5 to 8.5 because all ten carried products now price below the market median per milligram, a median of 0.72x, after price cuts on several products. Shipping rose from 5.0 to 5.5 on a newly published same-day dispatch cutoff and a free-shipping threshold. The lab rating is unchanged, because the certificate library is still the same single July round from a laboratory that does not publicly disclose an accreditation.

1. July 23, 2026AminoVaultUp 6.51 → 6.94 (+0.43)

   Re-audited from live COAs. Confirmed MDx BioAnalytical, Krause Analytical (verifiable through Finnrick, a legitimate third-party testing platform), and Chromate reports; shipping and lab credit raised. Two underfilled batches (BPC-157, GHK-Cu) and no sterility/heavy-metals panels were flagged.

2. July 23, 2026Apollo Peptide SciencesUp 7.55 → 7.70 (+0.15)

   Re-audited from live COAs, verified firsthand. Found ~30 Janoshik (A-tier) reports, mass-spec confirmed with public verify keys and 99%+ purity, which disproves the earlier note that claimed no published testing evidence. Lab and transparency were both raised (listed address, LLC, guarantee). Capped below the top tier because the panels are purity and content only, with no endotoxin, sterility, or heavy-metals. Note added 22 October 2026: under the laboratory checks published that day, Janoshik Analytical is graded tier B+, and the reports we read state no identity method (check L4).

3. July 23, 2026Ascension PeptidesUp 7.48 → 7.86 (+0.38)

   Re-audited from live COAs. Moved off stale MZ Biolabs data to their current Kovera Labs COAs (LC-MS identity, HPLC purity, endotoxin, heavy metals and a rapid sterility screen) on 27 of 30 products, while Ipamorelin, AOD-9604 and HCG stayed on MZ Biolabs reports, so the lab rating was raised.

4. July 23, 2026BioInfinityUp 8.40 → 8.48 (+0.08)

   Re-audited from live COAs. Verified 44 Verum Analytics reports (A-tier: purity, identity, content, endotoxin, with a public verify portal), affirming the high lab credit. Note added 22 October 2026: under the laboratory checks published that day, Verum Analytics is graded tier D: its existence and independence are not established (checks L1 and L2), so its certificates score a flat 2.0.

5. July 23, 2026BioLongevity LabsUp 7.88 → 7.94 (+0.06)

   Re-audited from live COAs. Corrected the lab of record from SafeCert to MDx BioAnalytical (2026, with endotoxin) plus BioRegen legacy reports, for a small lab-rating gain. Several overfilled batches were documented.

6. July 23, 2026BulkGLPUp 8.18 → 8.37 (+0.19)

   Re-audited from live COAs, read firsthand. Every report is Freedom Diagnostics Testing (A-tier), mass-spec confirmed. Notable upgrade: the GLP flagship line now adds endotoxin (USP<85> LAL), microbial PCR, and fentanyl screening on top of purity, so the lab rating was raised. Still no sterility or heavy-metals testing, which keeps it below the top tier.

7. July 23, 2026Honest PeptideUp 7.17 → 8.03 (+0.86)

   Re-audited from live COAs. Found current Freedom Diagnostics and Janoshik reports on the live site that we had previously undercredited, raising the lab rating substantially.

8. July 23, 2026Modern AminosUp 8.00 → 8.13 (+0.13)

9. July 23, 2026Nextday PeptidesUp 7.23 → 7.28 (+0.05)

   Re-audited from live COAs. Read 25 Janoshik reports in the vendor's certificate library and credited current transparency. Noted two mislabeled COA links and that only 28 of 59 products publish a COA.

10. July 23, 2026Oasis LabsDown 8.55 → 6.78 (-1.77)

    Re-audited and COAs verified firsthand. The testing is genuine per-product (Bioviridian, mass-spec-confirmed identity + HPLC purity), correcting an earlier assessment that had doubted it. But the panels cover identity, purity, and content only, with no sterility, heavy-metals, or endotoxin testing, plus QC issues (a mismatched vial photo, a sample-mockup file still live). The previous 9.5 lab rating was inflated, so the score was lowered to a verified level.

11. July 23, 2026Spartan PeptidesUp 4.76 → 5.26 (+0.50)

    Re-audited from live COAs. Verified 6 MZ Biolabs reports (identity + purity, no sterility/heavy-metals); shipping was raised. COA coverage is still thin across the catalog, which caps the score.

12. July 23, 2026Verified PeptidesUp 8.18 → 8.44 (+0.26)

    Re-audited from live COAs in July 2026. Janoshik test reports with separate endotoxin reports were read across the catalogue, and shipping, pricing and transparency were confirmed as strengths.
