A Certificate of Analysis is an independent third-party report confirming a compound's identity and purity via HPLC-UV chromatography and mass spectrometry. Peptology never relies on in-house testing — every batch is verified through our network of US, EU and Philippine partner laboratories. See how our testing works →
