   Market medians updated after Bluum Peptides was added pricing 7.8 to 7.7.

3. October 27, 2026Raised from7.86→to7.88(+0.02)

   Pricing recomputed on 27 October 2026: listings added for a newly reviewed vendor (Peptide Pro) moved the market median for the same products pricing 7.7 to 7.8.

4. October 26, 2026Lowered from7.88→to7.86(-0.02)

   Pricing recomputed on 26 October 2026: listings added for a newly reviewed vendor (StudzPeptides) moved the market median for the same products: pricing 7.8 to 7.7.

5. October 24, 2026Lowered from7.89→to7.88(-0.01)

   Pricing recomputed on 24 October 2026 after Bionova Peptides' first-review prices were recorded; other vendors move only through the market medians: pricing 7.9 to 7.8.

6. October 23, 2026Lowered from7.92→to7.89(-0.03)

   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 8.1 to 7.9.

7. October 22, 2026Lowered from7.98→to7.92(-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.

8. October 22, 2026Raised from7.87→to7.98(+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.

9. October 22, 2026Lowered from7.92→to7.87(-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.

10. October 22, 2026Raised from7.91→to7.92(+0.01)

    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 4.7 to 4.9.

11. October 22, 2026Raised from7.75→to7.91(+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.

12. October 22, 2026Raised from7.64→to7.75(+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.

13. October 22, 2026Lowered from8.47→to7.64(-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.

14. October 22, 2026Lowered from8.64→to8.47(-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.

15. October 22, 2026Raised from7.98→to8.64(+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.

16. October 21, 2026Lowered from8.13→to7.98(-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.

17. July 23, 2026Raised from8.00→to8.13(+0.13)
