A COA is the independent third-party lab report for a specific batch. It documents identity and purity by HPLC and LC-MS. Every order includes its batch COA, and you can view the verification links on our Testing page.
Each batch is tested by an independent lab (Janoshik) — HPLC for purity (≥99%), LC-MS for molecular-mass identity, plus endotoxin and sterility screening.
