1. November 2, 2026Lowered from2.66→to2.38(-0.28)

   Lab evidence re-checked on 2 November 2026 after our ranking review of 26 October. All 16 Titreon Analytical certificates for products the company sells opened at Titreon's new lookup with their printed keys. Titreon was added to our lab directory and graded as a laboratory whose independence is not established, so the certificates keep the flat 2.0. The Janoshik reports on the site are endotoxin screens, not identity or purity certificates. Fifteen products newly offered as pre-orders have no certificate yet and count under our coverage rule. Lab 1.7 to 1.2.

2. October 26, 2026Lowered from2.70→to2.66(-0.04)

   Pricing recomputed on 26 October 2026: listings added for a newly reviewed vendor (Lotus Peptide) moved the market median for the same products: pricing 1.5 to 1.2.

3. October 25, 2026Lowered from2.73→to2.70(-0.03)

   Pricing recomputed on 25 October 2026: listings added for a newly reviewed vendor (Pexo Labs) moved the market median for the same products: pricing 1.7 to 1.5.

4. October 24, 2026Raised from2.72→to2.73(+0.01)

   Prices re-computed on 24 October 2026 after products were added for Spartan Peptides, Next Day Peptides and Honest Peptide, which moved the market medians: pricing 1.6 to 1.7.

5. October 24, 2026Raised from2.74→to2.77(+0.03)

   Pricing recomputed on 24 October 2026: listings added for newly reviewed vendors moved the market median for the same products: pricing 1.4 to 1.6.

6. October 23, 2026Lowered from2.77→to2.72(-0.05)

   Certificate library re-checked on 23 October 2026: the vendor no longer publishes a BPC-157 certificate (the product page states that no certificate is published, and the earlier file returns not found), so BPC-157 now counts as having no certificate; its separate Janoshik endotoxin report is kept on record as an add-on report. Lab 1.8 to 1.7.

7. October 23, 2026Raised from2.71→to2.74(+0.03)

   Pricing recomputed on 23 October 2026 from current listings with the published rule (section E), after listings added or updated since 22 October, including a newly reviewed vendor's, moved the market median for the same products: pricing 1.2 to 1.4.

8. October 22, 2026Raised from2.66→to2.71(+0.05)

   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 1.7 to 1.8.

9. October 22, 2026Lowered from2.79→to2.66(-0.13)

   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 5.0 to 6.0, pricing 4.0 to 1.2, operating history 1.5 to 1.3, transparency 3.5 to 5.5.

10. October 22, 2026Raised from1.85→to2.79(+0.94)

    Lab score recalculated on 22 October 2026 under the uniform published rubric applied to every vendor: the published certificates, which our 1 October 2026 audit could not tie to an independent operating laboratory, now score the fixed 2.0 the rubric gives documents whose laboratory independence is not established, instead of zero. Lab 0.0 to 1.7.

11. October 21, 2026Lowered from2.29→to1.85(-0.44)

    Lab 0.8 to 0. The certificates contain features we could not reconcile with measured laboratory results and carry no laboratory lookup, so they are treated as no independent certificate, and three listed products have no certificate at all. Under our published rule the lab score is zero.
