Guides to reading the evidence
Plain, factual guides for the people who actually evaluate a supplier: how to read a certificate of analysis, how to verify purity independently, what “research use only” means, and how lyophilized peptides are stored and handled in the lab. Janoshik reports are verifiable by key. Reports come from Janoshik, an independent third-party lab, and each carries a verify key. A product without a report says so on its own page. All of this is educational and for laboratory research use only — no medical, therapeutic, or health claims.
