We read the certificates of analysis vendors publish, compare them with the lab's own record where we have built a check for that lab, and update every score daily.
No one at PeptidesAudit tests products. Every number comes from documents the vendor or the lab published, and from public review pages.
Our crawler reads each store's catalog and every lab report it links to, slowly and within its robots rules.
Lab, task number, compound, purity, measured amount and date. If a field is unclear, we leave it empty.
If the lab allows automated lookups and we have built a check for that lab, we compare the report with the lab's own record. If the lab only offers a lookup on its site, we show you the task number (and key) and the link.
Coverage, verification, the lab, results, freshness and public reviews. Same public method for everyone.
This is what we read on every certificate of analysis. We never re-publish a vendor's file: we show the data and link to the original.
The lab's own record for task EX-00000 matches this report.
The original file stays private as evidence, with its SHA-256 fingerprint.
Open a vendor to see how its score adds up. Its website opens only from that page.
Ranked by score only. We may earn a commission when you open a vendor’s site — it never changes the order. How we make money
No. We read the lab reports vendors publish and, where a lab allows automated lookups and we have built a check for that lab, compare them with the lab's own record. A score measures what a vendor's lab reports and public reviews show, not what is in a specific vial.
No. We may earn a commission when you open a store from a vendor's page, and that never changes a score or the order. Every vendor is measured with the same public method.
We found a report or task number shared with another report, or a report that does not match the lab's record. A person reviews every finding, the vendor is told first and has 7 days to reply, and the reply is published next to the finding. The score stays at 0 while the finding stands.
No. PeptidesAudit is information about published lab reports and reviews. It gives no advice on use, doses or protocols. See the disclaimer.
