Planet Peptide is a research-peptide seller tracked in the PeptideCensus index. The rankings table above lists every compound board it appears on, with scores and test dates refreshed daily from the published record.
Planet Peptide publishes a large, checkable testing record, but its store sits behind a registration gate, so PeptideCensus cannot verify it as a retailer.
The testing side is strong. As of October 2026, Freedom Diagnostics’ open database holds more than 500 certificates under Planet Peptide’s name, the newest dated 23 September 2026, and the Finnrick directory counts 63 published results. Each certificate listed on this page links to the original PDF on the lab’s own server.
The storefront is the problem. When we checked planetpeptide.com on 8 October 2026, it redirected to a registration gate, so products, prices and checkout were hidden until you create an account. We verify only storefronts we can assess the way a buyer would, so the listing stays unverified and out of our vendor rankings.
Whichever seller you use, match the certificate to the lab’s own records before trusting a vial: search its code in the Freedom Diagnostics lookup or check a Janoshik report with its key (how to verify a Janoshik report). A certificate covers one tested batch, so compare its batch number and date with the vial you receive.
