Every entry newest first

  1. Lowered from6.15to6.14(-0.01)

    Pricing recomputed on 24 October 2026 after Bionova Peptides' first-review prices were recorded; other vendors move only through the market medians: pricing 5.6 to 5.5.

  2. Raised from6.14to6.15(+0.01)

    Pricing recomputed on 24 October 2026: listings added for newly reviewed vendors moved the market median for the same products: pricing 5.5 to 5.6.

  3. Lowered from6.15to6.14(-0.01)

    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 5.6 to 5.5.

  4. Lowered from6.18to6.15(-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 5.8 to 5.6.

  5. Raised from6.16to6.18(+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 1.7 to 2.2.

  6. Raised from5.98to6.16(+0.18)

    Re-scored on 22 October 2026 under the published rulebook, which now gives one rule for each judgement call and applies it to every vendor: shipping and refunds 5.5 to 6.5, transparency 1.5 to 1.0.

  7. Raised from5.71to5.98(+0.27)

    Every listed product read and its certificate confirmed at the issuing laboratory on 22 October 2026 (the site was previously unreadable to our tools), so the lab score now follows our published lab rule. Lab 6.5 to 7.0.

  8. Lowered from6.14to5.71(-0.43)

    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 5.8 to 5.5, pricing 7.8 to 5.8, operating history 2.2 to 1.7, transparency 2.5 to 1.5.

  9. Raised from5.66to6.14(+0.48)

    Re-audit, read through a customer account because the catalog and certificate library are now behind registration. Lab rises from 5.17 to 6.5: all 23 Freedom Diagnostics certificates were verified at the laboratory, covering nearly the whole catalog, but they are identity and purity only, 9 to 12 months old, carry chemical registry numbers instead of batch codes, and the three below 99% are not shown on their product pages. Shipping falls from 7.2 to 5.8 because the 60-day money-back guarantee credited in May is gone and damage must be reported within 24 hours. Pricing rises from 7.2 to 7.8 on live standard prices about 17% above the market median. Tenure 2.0 to 2.2. Transparency falls from 4.0 to 2.5: no company, address or phone is published.

Score changes for every vendor are on the score changes page. Research Peptides Lab may display its current score with the score badge, which updates automatically and has no effect on the score.
