BPC-157
A healing compound made from a protein found in stomach fluid. It's the most studied peptide for tissue repair, with research showing it helps heal tendons, ligaments, muscles, the gut, and other organs. It's stable enough to survive stomach acid, so you can take it either by injection under the skin or by mouth.
BPC-157 (Body Protection Compound-157) is a 15-amino-acid synthetic peptide derived from a protective protein found naturally in human gastric juice. It is one of the most widely studied peptides in the healing and recovery category, with over 100 published research studies — though all evidence to date comes from animal models and cell culture experiments. No completed human clinical trials exist as of 2026, though several are underway.
The peptide's healing properties work through multiple complementary mechanisms. BPC-157 upregulates growth factor expression (VEGF, EGF, and others), stimulates angiogenesis to increase blood supply to damaged tissues, and modulates the nitric oxide system to reduce inflammation. It has shown remarkable effects in animal studies on tendon tears, ligament damage, bone fractures, muscle injuries, and gastrointestinal conditions including ulcers, inflammatory bowel disease, and leaky gut.
BPC-157 is typically administered by subcutaneous injection near the injury site for musculoskeletal conditions, or orally for gut-related issues. Its stability in gastric acid (owing to its origin in gastric juice) is unusual for a peptide and makes oral administration viable for certain applications. The main theoretical safety concern is that its pro-angiogenic properties could promote growth of existing tumors.

Neuroprotection

Mechanism of Action
BPC-157 is a synthetic pentadecapeptide (15 amino acids) derived from a protective protein found in human gastric juice. Its mechanism of action is remarkably multifaceted, affecting multiple organ systems and healing pathways simultaneously, which is unusual for a single peptide. The primary mechanism centers on the nitric oxide (NO) system — BPC-157 modulates both constitutive (eNOS) and inducible (iNOS) nitric oxide synthase, and can either promote or inhibit NO production depending on the tissue context and injury state.
BPC-157's regenerative effects are mediated through upregulation of multiple growth factors. It increases expression of vascular endothelial growth factor (VEGF), promoting angiogenesis — the formation of new blood vessels at injury sites, which is critical for delivering oxygen and nutrients for tissue repair. It also upregulates epidermal growth factor (EGF), nerve growth factor (NGF), and hepatocyte growth factor (HGF) receptors, supporting wound healing, nerve regeneration, and organ protection respectively. In tendon and ligament injuries, BPC-157 stimulates fibroblast migration and proliferation, accelerating collagen deposition and organized tissue repair rather than scar formation.
Beyond structural healing, BPC-157 has significant effects on the central and enteric nervous systems. It modulates dopaminergic, serotonergic, GABAergic, and opioid systems, which may explain reported effects on mood, gut function, and pain perception. It protects endothelial function, counteracts the effects of NSAIDs on the gastric mucosa, and has demonstrated cytoprotective effects in models of liver, brain, heart, and intestinal damage. The peptide also interacts with the FAK-paxillin pathway, which is central to cell adhesion and migration during wound healing. Its stability in gastric juice — unusual for a peptide — enables oral administration, making it one of the few peptides effective by both injectable and oral routes.
Regulatory Status
