Every claim, sourced.
No exceptions.
Every claim on this site traces back to a public source. Below is what we use and how.
Vendor websites (HQ, founded, prices, listings, payment, languages, affiliate terms). We re-check every 30 days; pricing PRs ship weekly.
COAs published by the vendor or by independent labs (Janoshik Analytical for the EU-segment blind multi-lab). We render specimens verbatim — no edits to spec/result rows.
Trustpilot snapshot (rating + count). We do not mirror review text. Removed-review clusters are tracked as incidents when corroborated.
Regulator filings (NBR, ANVISA, FDA, etc.), corroborated forum reports, and public GDPR breach notifications. Each entry lists its sources inline.
Peer-reviewed publications cited on each peptide page (year, journal, citation count where known, DOI when public). Selected for relevance to the research-use context the peptide is sold under, not for marketing claims.
