Peptide testing · by compound

Peptides we test.

We're an independent, third-party peptide testing lab — mail us a vial and we confirm identity, chromatographic purity, and net-peptide assay (mg/vial) by RP-HPLC-UV, as a verifiable certificate of analysis. Pick a compound for the details below, see the full panel further down, or start an order.

Blends we run

A blend is one vial with more than one active. We resolve and report every compound in it separately — each gets its own identity, purity, and mg per vial on the certificate. Pick one on the order form and the usual split fills itself in; adjust it if yours differs.
