1. October 22, 2026Lowered from5.95→to5.79(-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.

2. October 22, 2026Raised from5.78→to5.95(+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.

3. October 22, 2026Lowered from5.84→to5.78(-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.

4. October 22, 2026Raised from5.82→to5.84(+0.02)

   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 6.5 to 6.9.

5. October 22, 2026Lowered from6.02→to5.82(-0.20)

   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 7.2 to 7.0, operating history 6.8 to 6.5, transparency 4.5 to 3.5.

6. October 22, 2026Raised from5.52→to6.02(+0.50)

   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 4.5 to 5.4.

7. October 18, 2026Raised from4.11→to5.52(+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.
