How to read a COAA Certificate of Analysis lists the tested identity, HPLC purity, net peptide content, and appearance for one specific production lot. Because peptides are made in discrete batches, always match the lot number on your vial to the certificate, a generic, lot-less "COA" verifies nothing.
