a widely discussed investigational peptide with substantial preclinical research and very limited human evidence. Preclinical work has examined growth-factor signaling, angiogenesis-related pathways, gastrointestinal models, and connective-tissue injury.
In animal models, BPC-157 accelerated tendon-to-bone healing by 72% compared to controls over a 14-day observation period.

BPC-157 activates the FAK-paxillin pathway, promoting tendon fibroblast migration and outgrowth. It upregulates vascular endothelial growth factor (VEGF) receptor expression, accelerating angiogenesis at injury sites. In the gut, it interacts with the dopaminergic and nitric oxide (NO) systems to protect mucosal integrity and counteract NSAID-induced damage.
BPC-157 has a substantial preclinical literature, primarily in rodent models, spanning tissue injury, gastrointestinal models, and other systems. Human evidence is far smaller. A 2025 IV pilot involved only two adults and cannot establish safety across populations, routes, or long-term use.
Human safety evidence is too limited to characterize common adverse effects or long-term risks. FDA reviewers have highlighted uncertainty around immunogenicity, peptide-related impurities, active-ingredient characterization, and route-specific risk. The two-person IV pilot reported no adverse effects during its brief observation period, but that is not enough to establish safety.
BPC-157 is not an FDA-approved drug. It was removed from Category 2 after the underlying nominations were withdrawn, and in July 2026 the PCAC recommended adding BPC-157 free base and acetate to the 503A Bulks List. The recommendation is non-binding and final FDA action remains separate.
