1. November 6, 2026Raised from4.39→to4.45(+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.

2. November 2, 2026Raised from3.90→to4.39(+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.

3. November 2, 2026Raised from3.68→to3.90(+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.

4. October 26, 2026Raised from3.66→to3.68(+0.02)

   Pricing recomputed on 26 October 2026: a vendor was removed from the directory, which moved the market median for the same products: pricing 7.7 to 7.8.

5. October 23, 2026Raised from3.33→to3.66(+0.33)

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

6. October 23, 2026Lowered from3.35→to3.33(-0.02)

   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 7.8 to 7.7.

7. October 22, 2026Raised from3.18→to3.35(+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 0.7 to 1.0. Note added 22 October 2026: a score on this entry was corrected from 3.34 to 3.35; it had been rounded down instead of half up.

8. October 22, 2026Raised from3.11→to3.18(+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 6.6 to 8.0.

9. October 22, 2026Lowered from3.21→to3.11(-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: transparency 6.5 to 4.5.

10. October 22, 2026Lowered from3.27→to3.21(-0.06)

    Re-scored on 22 October 2026 under version 2 of our published rules. The BPC-157 document names no laboratory and now scores the flat 2.0 that applies to every certificate whose source cannot be established. The testing gate is now computed from the certificates, and none of 33 products has a certificate confirmed at a directory laboratory. Lab 0.8 to 0.7. Score 3.27 to 3.21.

11. October 22, 2026Lowered from4.57→to3.27(-1.30)

    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 9.5 to 5.0, pricing 10.0 to 7.8, operating history 10.0 to 6.6, transparency 4.6 to 6.5.

12. October 21, 2026Lowered from6.19→to4.57(-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.

13. July 23, 2026Re-checked, no change

    Re-audited from live COAs. Refreshed 7 MZ Biolabs reports; one anonymous BPC-157 COA with no named lab remains a concern, and sparse COA coverage keeps the lab rating low.
