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 is an independent, non-commercial project, put together out of research and personal interest. We're not a vendor and aren't affiliated with any seller. The whole point is to gather information that's scattered across the internet, attribute it to its source, and present it as-is — with nothing else mixed in — for your reference. Rankings and scores are built only from objective, sourced signals.

The independent test data on vendor and peptide pages are third-party results, aggregated from several raters and attributed to each with a link back: Finnrick (per-peptide A–E safety grades), PeptideBenchmark (a 0–10 benchmark), VialAudit (anonymous blind-buy audits), and Peptigrity (per-test HPLC purity, attributed to the lab that actually ran it — Janoshik, Vanguard, Freedom Diagnostics and others). None of it is our own testing or an endorsement. Where a peptide has no independent test data, we say so rather than imply it exists.

The peptideone Score is our single 0–10 headline for a vendor — a weighted blend of the independent test signals each vendor has: Finnrick safety grade (weight 0.45), VialAudit blind-buy audit (0.30), and Peptigrity HPLC purity (0.25). The weights renormalize over whatever signals a vendor actually has, and each vendor page shows how many independent sources went into its score.

We deliberately exclude PeptideBenchmark from the score: it is itself a blend of Finnrick and Peptide Critic, so counting it would count the same lab tests twice. For the same reason we exclude the Peptigrity trust score, which re-blends its own HPLC data. Both are shown as separate, attributed cross-references instead. The score is computed only from public, attributed data and recomputes as new data lands — nothing else feeds into it.

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.
