# How do I read a peptide certificate of analysis?

A usable CoA names the laboratory, the batch, the method, the date, and a result that matches the vial in hand.

Every listed batch has a certificate of analysis. Email the order id or the lot on the vial to hello@evolvpeptides.co.uk and the file for that batch is sent. A paper certificate is not in the carton.

Certificate of analysis on request via hello@evolvpeptides.co.uk. A paper certificate is not in every carton. HPLC ≥99% is the batch-release specification.
