7. October 23, 2026Raised from7.03→to7.30(+0.27)

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

8. October 22, 2026Lowered from7.14→to7.03(-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.

9. October 22, 2026Lowered from7.24→to7.14(-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 2.5 to 0.5.

10. October 22, 2026Raised from6.96→to7.24(+0.28)

    Re-scored on 22 October 2026 under version 2 of our published rules. The seven Bioviridian certificates were confirmed at the laboratory, which raises each of them by the 1.5 points for a confirmed key. Lab 7.5 to 8.0. Score 6.96 to 7.24 (Fair to Strong).

11. October 22, 2026Lowered from7.23→to6.96(-0.27)

    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 7.0, pricing 7.0 to 7.6, operating history 3.2 to 3.4, transparency 6.0 to 2.5.

12. October 22, 2026Raised from6.69→to7.23(+0.54)

    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 certificates more than 12 months old and one lot number printed on certificates for different compounds. Lab 6.5 to 7.5.

13. October 21, 2026Lowered from6.78→to6.69(-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.

14. July 23, 2026Lowered from8.55→to6.78(-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.
