Certificate of Analysis

Every lot ships with its certificate. Lost yours, or want to check it before you order?

Printed on the vial label and on the packing slip.

What's on it

Purity by HPLC with the chromatogram, identity by mass spectrometry with observed and expected mass, water content, net peptide content, counterion, and solubility — against the specification for that product.
