About & methodology

Every datapoint is summarized from public sources and links back to its origin — PubChem for chemical identity, PubMed for the literature, independent labs for test grades. Our summaries are digests of the cited sources, not original assertions. We don't invent findings or make efficacy claims.

peptideone does not sell peptides and is not a vendor. We may, in future, accept donations or disclosed vendor certifications and ads — but, like ads versus organic search results, money never affects what the data says or how anything is ranked. Any sponsored label is disclosed and is decoupled from ranking, which is built only from objective signals.

The independent test grades on vendor and peptide pages are third-party results, currently aggregated from Finnrick and attributed to them with a link back. They are not our own testing and not an endorsement. Where a peptide has no independent test data, we say so rather than imply it exists.

We do not give dosing, reconstitution, or administration advice for human use; we catalog buyer concerns and link to primary sources instead. We publish no efficacy or therapeutic claims and no “approved/scam” verdict lists. The compounds discussed are sold for research use and are not approved for human consumption. Nothing here is medical, legal, or financial advice.

Chemical identity and literature are fetched from public APIs and refreshed automatically. Plain-language summaries are generated by a language model strictly from the cited sources and pass an automated faithfulness + guardrail check before publishing; anything that fails is withheld rather than shown. Everything carries its provenance.
