Overview

Body Protection Compound-157 (BPC-157) is a synthetic pentadecapeptide composed of 15 amino acids. It is a partial sequence of body protection compound (BPC) that is naturally found in human gastric juice. Since its discovery, BPC-157 has been the subject of extensive preclinical research demonstrating many cytoprotective and healing effects across multiple organ systems. Unlike many peptides that degrade rapidly, BPC-157 shows notable stability in human gastric juice, which is unusual for peptides of its size. Research has explored its potential in tendon-to-bone healing, muscle repair, nerve regeneration, anti-inflammatory responses, and gastrointestinal protection. While clinical trial data in humans remains limited, the breadth and consistency of animal study results have generated significant interest in the research community.

Mechanism of Action

BPC-157 exerts its effects through multiple pathways. It has been shown to upregulate growth hormone receptor expression and stimulate the FAK-paxillin pathway, which is important for cell migration and tissue repair. The peptide modulates the nitric oxide (NO) system, which plays a role in blood vessel formation and maintenance. It promotes angiogenesis (new blood vessel formation) through VEGF pathway activation, supporting nutrient delivery to injured tissues. BPC-157 also interacts with the dopaminergic, serotonergic, and GABAergic systems, suggesting broader neurological implications. Additionally, it has demonstrated effects on the JAK-2/STAT-3 signaling pathway, which is involved in cell proliferation, differentiation, and immune regulation. One of its most distinctive mechanisms is the ability to counteract the effects of various toxic agents and NSAIDs on the gastrointestinal lining, providing cytoprotective effects even under chemically challenging conditions.

Animal studies show promotion of peripheral nerve regeneration after transection or crush injuries. BPC-157 may accelerate nerve sprouting and functional recovery of neurological pathways.

Blood Vessel Formation

Moderate Evidence

BPC-157 promotes angiogenesis through VEGF-related pathways, potentially improving blood supply to injured areas. This mechanism supports its broader tissue healing properties.

Bone Healing

Preliminary

Preliminary research suggests accelerated bone fracture healing and improved bone-tendon junction repair. Studies are primarily in animal models with segmental bone defects.
