1. November 3, 2026Lowered from6.50→to6.34(-0.16)

   Certificates re-checked on 3 November 2026. The newest JD-2TR (tirzepatide) certificate the company posts is now a PuriLab Analytical report of 29 October 2026 for the 60 mg size, which resolves at PuriLab's own lookup. Under the published rule that the newest certificate per product counts (A6), tirzepatide is now scored from it, and because PuriLab's site names no operating company or street address it is not an established laboratory in our directory, so the certificate earns the minimum score. The earlier ILS certificates for the same product remain posted. Lab evidence 7.3 to 7.0.

2. November 2, 2026Raised from6.49→to6.50(+0.01)

   Market medians updated after the 2 November re-checks pricing 5.8 to 5.9.

3. November 2, 2026Lowered from6.71→to6.49(-0.22)

   A Wolverine blend of BPC-157 and TB-500 was added to the catalogue in November 2026. Its certificate is from PuriLab Analytical, whose report resolves at its own lookup, but whose site names no operating company or street address, so it is not an established laboratory in our directory and the certificate earns the minimum score. Lab 7.7 to 7.3.

4. October 29, 2026Lowered from6.74→to6.71(-0.03)

   Market medians updated after Delix Labs and Ageless Peptides were added pricing 6.0 to 5.8.

6. October 27, 2026Raised from6.74→to6.75(+0.01)

   Pricing recomputed on 27 October 2026: listings added for a newly reviewed vendor (Peptide Pro) moved the market median for the same products pricing 6.0 to 6.1.

7. October 26, 2026Lowered from6.75→to6.74(-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 6.1 to 6.0.

8. October 24, 2026Lowered from6.78→to6.75(-0.03)

   Pricing recomputed on 24 October 2026 after Bionova Peptides' first-review prices were recorded; other vendors move only through the market medians: pricing 6.3 to 6.1.

9. October 23, 2026Lowered from6.90→to6.78(-0.12)

   Prices re-checked on 23 October 2026 under rule E (standing prices only): prices taken from a time-limited sale were replaced with the vendor's standing price, current prices were re-read, and other vendors' price changes moved the market medians pricing 7.1 to 6.3.

10. October 22, 2026Lowered from7.16→to6.90(-0.26)

    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 6.5, pricing 6.0 to 7.1, operating history 2.0 to 1.0, transparency 6.5 to 5.0.

11. October 22, 2026Lowered from7.71→to7.16(-0.55)

    Lab score recalculated on 22 October 2026 under the uniform published rubric applied to every vendor: ILS Laboratories, which issued certificates relied on here, does not publish ISO/IEC 17025 accreditation, so the accreditation point no longer applies; fixed deductions apply for one lot number printed on certificates for different compounds. Lab 8.7 to 7.7. Note added 22 October 2026: PJLA's register lists ILS Laboratories' accreditation (certificate L25-631) as suspended from 22 October 2026; the accreditation point still does not apply (check L6).

12. October 21, 2026Raised from7.05→to7.71(+0.66)

    Lab 7.5 to 8.7. The earlier 7.5 had no recorded arithmetic. Recomputed under our published rule, which averages the lab score over the products we list and counts a listed product with no certificate as zero: all 17 listed products carry ILS Laboratories certificates confirmed at the laboratory's portal, from a laboratory that states ISO/IEC 17025 accreditation, with no endotoxin or sterility testing. A small deduction applies because the same lot labels appear on certificates for different compounds.

13. October 14, 2026Lowered from7.12→to7.05(-0.07)

    Catalog refreshed at the vendor's request: regular prices rose on most non-GLP products and five products were added. All five new certificates verified at ILS. Lab, shipping, tenure and transparency unchanged.
