Testing & certificates of analysis

Every kit ships with the certificate of analysis for the lot inside it. Nothing leaves the warehouse untested.

What is tested

Identity and purity by HPLC, with mass spectrometry confirmation of molecular weight, performed by an independent third-party laboratory. Release specification is 99%+ purity for every peptide SKU.
Net content is verified against the labelled amount per vial.
Lab supplies (bacteriostatic water, acetic acid water) are USP-grade and ship with the manufacturer's lot certificate.

How COAs reach you

A printed lot COA is packed inside every kit.
The lot number is printed on the kit carton and on its COA.
PDF copies for any lot you have purchased are available on request from [email protected].
