BPC-157, or Body Protection Compound-157, is a stable gastric pentadecapeptide composed of 15 amino acids. Originally discovered in human gastric juice, it has garnered significant attention for its remarkable regenerative and cytoprotective properties observed in numerous preclinical studies [1].

Mechanism of Action

BPC-157 exerts its therapeutic effects through several interconnected pathways [1]:

• Angiogenesis: It significantly promotes the formation of new blood vessels (angiogenesis) by enhancing vascular endothelial growth factor receptor-2 (VEGFR2) activity and nitric oxide (NO) synthesis, primarily through the Akt-eNOS pathway. This is crucial for delivering oxygen and nutrients to injured tissues, especially in poorly vascularized areas like tendons and ligaments [1].
• Inflammation Modulation: BPC-157 demonstrates potent anti-inflammatory properties by decreasing pro-inflammatory cytokines such as TNF-α, IL-6, and IFN-γ. It also shifts macrophage activity towards a reparative (M2) phenotype, reducing fibrosis and promoting tissue regeneration [1].
• Fibroblast Activity and Collagen Synthesis: It accelerates tendon and ligament repair by enhancing fibroblast proliferation and collagen synthesis, largely through focal adhesion kinase (FAK)-paxillin signaling pathways. It also increases growth hormone receptor (GHR) expression in fibroblasts, augmenting the anabolic healing response [1].
• Neuromuscular Stabilization: BPC-157 preserves neuromuscular function by stabilizing acetylcholine receptors and nerve terminals at the neuromuscular junction (NMJ). It also helps normalize disrupted neurotransmitter signaling in the central nervous system, aiding in recovery from nerve injuries [1].
• Cytoprotection: It protects cells from damage by upregulating cytoprotective factors like heme oxygenase-1 (HO-1) and heat shock proteins, preserving mitochondrial integrity and reducing oxidative stress [1].
