Peptide Sciences™ is a specialized peptide synthesis company that manufactures and supplies highly purified peptides, proteins, and amino acid derivatives for scientific research and development. We utilize automated and manual solid-phase peptide synthesis (SPPS) technology alongside in-house analytical testing (HPLC-MS) to verify purity, identity, and sequential accuracy. Our catalog includes research peptides such as BPC-157, tirzepatide, retatrutide, semaglutide, and tesamorelin — all exceeding 99% purity unless otherwise specified. We are not a compounding pharmacy, a clinic, or a supplement company.
