Certificates of Analysis
Every certificate here comes from Freedom Diagnostics, an independent laboratory. Each tested lot is checked for purity by HPLC, for identity by mass spectrometry, and for net peptide content, the amount of peptide by weight in the vial. Each card shows the lot's HPLC purity, links to the full certificate, and links to the product. Certificates stay published after a lot sells out. To check a report yourself, see how to verify a COA, or compare every lot in the purity report.
Sequences, formulas and molecular weights are listed in our compound reference.
