Independently HPLC-tested peptides for laboratory research, shipped cold-chain with a batch-specific COA attached to every order.
ProLine Peptides was founded on a simple premise: researchers deserve reagents they don't have to double-check. Every compound we release is synthesized to order, verified by independent HPLC and mass spectrometry analysis, and shipped under proper cold-chain conditions.
We work exclusively with laboratories and qualified research institutions. No compound leaves our facility without a batch-specific certificate of analysis attached.
