# Do you put a COA in the box?

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.

HPLC ≥99% is a batch-release specification: the lot was checked against that threshold before packing. It is not independent clinical proof, not a sterility certificate, and not a licence for human use.

The lot number is marked on every vial.

Email the order id or the lot on the vial to hello@evolvpeptides.co.uk. The certificate for that batch is sent. It is not printed in the carton.
