Verify a PatriotBiologics Certificate of Analysis
Every PatriotBiologics research peptide ships with an independently tested Certificate of Analysis (COA) confirming 99%+ purity.
A Certificate of Analysis (COA) is an independent, third-party laboratory report that documents the identity, purity, and quality of a research peptide. For every batch we synthesize, PatriotBiologics commissions HPLC and mass spectrometry testing and publishes the results as a COA bearing a unique certificate number, lot number, test date, and expiration.
A COA is what separates a verified, research-grade peptide from an unverified one. By cross-checking the certificate number on this page against the lot printed on your vial, you confirm that the product in your hand was tested to 99%+ purity by a lab unaffiliated with the manufacturer.
