# What does HPLC ≥99% mean?

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.

A percentage on a webpage is not the same as a lot file you can inspect. We will not treat HPLC as a marketing authorisation or as sterility.

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.

See Quality for the full standard, including what we refuse to claim.
