- Raised from4.52to4.54(+0.02)

- Lowered from4.54to4.52(-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 2.4 to 2.3.
- Re-checked, no change (4.54)
Re-scored on 22 October 2026 under version 2 of our published rules. No score change. The testing gate is now computed from the certificates instead of set by hand: 7 of 41 products have a certificate from a directory laboratory with the key confirmed at the laboratory, fewer than the half required, so the testing cap applies; the cap sits above the weighted score, so it does not lower it.
- Lowered from5.24to4.54(-0.70)
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. pricing 6.5 to 2.4, operating history 2.0 to 1.2, transparency 4.5 to 3.5.
- Raised from5.07to5.24(+0.17)
Lab score recalculated on 22 October 2026 under the uniform published rubric applied to every vendor: an earlier method deduction that is not part of the published rubric was removed; fixed deductions apply for certificates ordered by a supplier or issued to another business. Lab 4.5 to 4.8.
- Raised from4.52to5.07(+0.55)
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 41 of the 41 products we list that the vendor offers for sale. Lab 3.5 to 4.5.
- Re-checked, no change (4.52)
No score change. Third-party testing is now shown as not independently verified: the certificates are confirmed with the testing platform rather than with the laboratories, and no listed product has a laboratory-confirmed certificate. The overall score is unchanged because the testing cap sits above Based Research's score. The public notes were also corrected: the certificates cover identity, purity and assay, with no endotoxin or sterility testing.
