What BPC-157 Is
BPC-157 stands for Body Protection Compound-157. It is a synthetic pentadecapeptide (15 amino acids) with the sequence Gly-Glu-Pro-Pro-Pro-Gly-Lys-Pro-Ala-Asp-Asp-Ala-Gly-Leu-Val. The molecule has a calculated molecular weight of approximately 1419.53 g/mol and was originally derived from a partial sequence of a protein isolated from human gastric juice. Its complete chemical record is catalogued at PubChem CID 9941957.
Structural Features
The peptide contains three consecutive proline residues (positions 3–5), which give it unusual structural rigidity. Proline-rich segments are uncommon in synthetic peptides and contribute to BPC-157’s notable stability in acidic environments. Unlike many short peptides that degrade rapidly in gastric pH, BPC-157 retains structural integrity across a broad pH range — a property documented across multiple stability studies.
Research Applications
BPC-157 has been studied across a wide range of preclinical contexts including soft tissue research models, gastrointestinal lining research, and vascular formation research. The body of literature is concentrated in rodent models, primarily from research groups in Croatia and Eastern Europe. It is important to emphasize that all published work to date remains in the preclinical category — there are no approved human therapeutic indications for BPC-157, and the FDA has not approved it for any clinical use.
Analytical Standards at VialPepLab
Every batch of BPC-157 in our catalog is verified by reverse-phase HPLC to a minimum purity of 99% and identity-confirmed by LC-MS. The Certificate of Analysis shipped with each vial documents the exact purity percentage for that specific batch. Lyophilized BPC-157 remains stable at -20 °C for 24+ months when sealed and protected from light — see our Storage & Reconstitution Protocol for details.
BPC-157 belongs to a broader family of short regeneration peptides — read about the pentadecapeptide family for a comparison with TB-500, KPV, and related compounds. Available in Healing & Regeneration category formats.
