BPC-157

BPC-157 is a synthetic 15-amino acid pentadecapeptide (sequence GEPPPGKPADDAGLV; CAS 137525-51-0; MW 1419.5 g/mol) originally characterized from a protein sequence found in human gastric juice. It holds a distinctive position in peptide research for two reasons: the remarkable breadth of biological systems in which research activity has been demonstrated, and its exceptional physicochemical stability — particularly its documented resistance to degradation in the highly acidic, enzyme-rich environment of simulated gastric juice for periods exceeding 24 hours.

The primary studied mechanism centers on the VEGF/VEGFR2-Akt-eNOS signaling axis. Research data consistently show BPC-157 activating this pathway to promote angiogenesis — the formation of new capillary networks — at injury sites. Concurrently, it modulates the nitric oxide (NO) system, upregulates Early Growth Response gene 1 (EGR-1), and demonstrates anti-inflammatory activity through reduction of pro-inflammatory cytokine expression.

In musculoskeletal models, BPC-157 has demonstrated accelerated tendon-to-bone healing, improved ligament repair, and enhanced muscle regeneration following crush injury. In gastrointestinal models — the tissue system most studied given its gastric origin — it has shown ulcer healing, fistula repair, and inflammatory bowel disease model improvement. Neurological models have documented cytoprotective effects including dopaminergic system modulation, spinal cord injury improvement, and peripheral nerve regeneration.

Each General Peptide vial is independently verified by ISO 17025-accredited third-party U.S. laboratories using HPLC purity analysis, mass spectrometry identity confirmation, net content verification, ICP-MS heavy metal screening, and LAL endotoxin assay — with the full Certificate of Analysis published for every batch.

The following compounds operate through distinct, non-overlapping mechanisms that complement this product's research pathways. Each is independently available from the General Peptide catalog.
