1. November 3, 2026Raised from5.93→to5.95(+0.02)

   Market medians updated on 3 November 2026 after the NextGen Peps re-check added priced listings: pricing 7.9 to 8.0.

2. November 3, 2026Lowered from6.37→to5.93(-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.

3. November 1, 2026Raised from6.36→to6.37(+0.01)

   Market medians updated after Stack Research was added pricing 7.8 to 7.9.

4. October 26, 2026Lowered from6.37→to6.36(-0.01)

   Pricing recomputed on 26 October 2026: listings added for a newly reviewed vendor (StudzPeptides) moved the market median for the same products: pricing 7.9 to 7.8.

5. October 26, 2026Raised from6.36→to6.37(+0.01)

   Pricing recomputed on 26 October 2026: a vendor was removed from the directory, which moved the market median for the same products: pricing 7.8 to 7.9.

6. October 26, 2026Lowered from6.37→to6.36(-0.01)

   Pricing recomputed on 26 October 2026: listings added for a newly reviewed vendor (Lotus Peptide) moved the market median for the same products: pricing 7.9 to 7.8.

7. October 23, 2026Lowered from6.39→to6.37(-0.02)

   Pricing recomputed on 23 October 2026 under the revised rule E1 (standing offers), which prices a size at the lowest total a buyer can pay without a code under standing prices, so a standing offer that includes a second vial at no extra cost now counts at all the milligrams received, in the vendor's own price and in the market medians for the same products: pricing 8.0 to 7.9.

8. October 22, 2026Raised from5.78→to6.39(+0.61)

   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.

9. October 22, 2026Raised from5.73→to5.78(+0.05)

   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.

10. October 22, 2026Raised from5.67→to5.73(+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 5.6 to 5.7.

11. October 22, 2026Raised from5.51→to5.67(+0.16)

    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 5.3 to 5.6.

12. October 22, 2026Lowered from5.53→to5.51(-0.02)

    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 5.0, pricing 7.2 to 8.0, operating history 2.7 to 2.3, transparency 5.9 to 5.5.

13. October 22, 2026Raised from5.42→to5.53(+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 and site statements about testing that the certificates do not bear out. Lab 5.1 to 5.3.

14. October 20, 2026Lowered from7.12→to5.42(-1.70)

    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.

15. October 8, 2026Raised from6.90→to7.12(+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>.

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

    Re-audited from live COAs. Verified BioRegen and Janoshik reports (the newest add endotoxin). Flags: an SS-31 underfill near 80% and one elevated BPC-157 endotoxin reading.
