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, or start an order.
