COA & Canadian Third-Party Testing
Independent, verifiable Canadian third-party testing
All third-party testing conducted by Integrity Peptides is performed through independent Canadian analytical laboratories. Certificates of Analysis (COAs) are generated from laboratory-tested samples and are intended to support independent verification of identity and purity.
Integrity Peptides is committed to third-party verification across our entire product line. Testing documentation is published once results are finalized and reviewed. We do not publish preliminary, supplier-only, or unverified test data.
Current testing status, available Certificates of Analysis, and verification details are maintained on our Third-Party Testing & Certificates of Analysis page.
