How the score is built67 / 100
Report authenticityiCan the issuing laboratory independently verify the reports the vendor publishes?20 / 208 of 8 reports confirmed by the issuing laboratory.
Testing coverageiWhat share of listed products, and of each size sold, carries a published report?0 / 1020 of the 99 products in this catalogue have a report, covering 5 of 286 sizes. This measures the catalogue, not the reports.
Report recencyiHow recently was each published report issued by the laboratory?8 / 10The median report is 4 months old. 0 of 3 were issued within 3 months.
Measured purityiWhat purity did the laboratory actually report, averaged across confirmed reports?4 / 10Purity averages 99.47% across the 8 of 8 confirmed reports that state a purity figure, with the lowest at 98.84%. That is 4 of 10 points. 2 points for each 0.1% above 99.0%, reaching 10 at 99.5%. Anything at or under 99.0% scores nothing. Those 8 figures cover under a tenth of the catalogue, so this line is capped at 4 rather than the 8 the purity alone would earn.
Legal complianceiWhether the storefront and its paid advertising stay inside research-use language.6 / 10The storefront carries no human-use claims in its copy, a customer service address and no mixing instructions. It lacks a research-use gate, research-use labelling and a published telephone number. The public Ad Library could not provide a complete result. Advertising is excluded from this score; no claim about the vendor's ads is made.
PricingiPrice per milligram against the market median for the same compounds.9 / 20Median price per milligram is 1.38x the market median, 38% above comparable vendors.
StorefrontiDispatch, whether the shop can be moved through, the range on the shelf, and what the vendor discloses.20 / 20The vendor commits to dispatch in under 2 business days, with tracking. It publishes: "LEGAL Privacy Policy Terms and Conditions Returns and Refund Policy EMAIL Info@peptidelabs.us QUICK LINKS Home Order Peptides Blog About Contact FAQ SHIPPING DAYS Monday to Friday Expect within 24 hours for order processing and 2–3 days for delivery." The vendor publishes a contact route, its policies and batch numbers on 8 of 8 reports. 99 products listed. The storefront reaches a catalogue of 99 products, reachable policy pages and a reachable contact route. Page load is not timed.

Certificates with an identified independent laboratory and a verification route are checked with that laboratory. A report counts as authentic only when the laboratory holds it and the laboratory’s own copy names this vendor as the client. Laboratories that publish no public verifier are recorded Unverifiable, not Failed. A documented absence of an independent issuing laboratory and verification route fails the certificate checks; it does not establish fabrication or accreditation status.

Findings describe the certificates this vendor published on the dates listed. The weight each category carries, and what it measures, is set out once for every vendor.

A category marked not assessed could not be measured here, and it is left out of the total rather than counted as zero. A published record carries no unanswered line: where an automated check cannot settle one, the line is settled from what the storefront publishes. Every published vendor is audited again once a month.
