Peptide Certificates of Analysis (COA)

Every batch. Third-party analysis verified. No exceptions.

Noxa Labs partners with accredited independent laboratories to test every product for identity, purity, and potency – using HPLC and Mass Spectrometry. You get batch-specific Certificates of Analysis before you buy, not after.

Our preferred testing partner is Freedom Diagnostics — an ISO-accredited laboratory known for rigorous analytical standards and trusted by researchers and compounders across the industry. Every COA on this site includes a matching batch number you can independently verify directly on their website at freedomdiagnostics.com.
