The gold standard for recovery and injury repair. Derived from gastric juice protein.
BPC-157 (Body Protection Compound 157) is a synthetic 15-amino acid peptide sequence derived from a protein found in human gastric juice. Despite its gastric origins, it has systemic effects throughout the body — a property that makes it uniquely versatile among research peptides.
The peptide works primarily through the FAK-paxillin signaling pathway, which is central to cellular migration and tissue repair. It also promotes the formation of new blood vessels (angiogenesis), upregulates growth hormone receptor expression, and modulates both the dopaminergic and serotonergic systems — which explains the occasional mood and gut motility improvements users report.
BPC-157 is one of the most extensively self-experimented peptides in the community, with a safety profile that appears favorable across a broad range of doses in animal studies. Human trials are limited but anecdotal reports are extensive and largely consistent.
Accelerated healing of tendons, ligaments, and muscles. Particularly notable for tendon injuries which typically heal slowly.
Multiple animal studies show 2-3x faster tendon healing
Reduces inflammation in the GI tract. Users with IBS, Crohn's, or general gut issues frequently report significant improvement.
Strong preclinical data for IBD; mechanism via VIP/NO system
Anti-inflammatory effects across multiple systems. Often used after surgery or intense training for systemic inflammation reduction.
Multiple pathways of anti-inflammatory action documented
Reduction in chronic joint pain and arthritis symptoms. Some users report effects within days on joint inflammation.
Animal models show significant benefit; human reports consistent
We rate every peptide honestly across four dimensions — and tell you what it's not.
Evidence Profile
Extensive, consistent animal data for tissue and gut healing, but no published controlled human trials. Human use is anecdotal.
Mostly preclinical (animal/in-vitro) evidence with a clear mechanism. Human effects are largely anecdotal.
Controlled trials & clinical data in people
No published randomized controlled trials in humans. Reports are anecdotal.
Preclinical results in animal models
Large, consistent body of rodent studies for tendon, gut, and wound healing.
How plausibly it works at a biological level
Plausible angiogenic and FAK-paxillin pathway effects; mostly characterized in animals.
Depth of documented safety in humans
Favorable short-term animal safety; long-term human safety is undocumented.
Active men with injuries, athletes with nagging pain, anyone dealing with gut issues or recovering from surgery
Can be used continuously at 250-500mcg/day. No hormonal interactions. Commonly stacked with TB-500 for comprehensive healing.
Women with sports injuries, gut issues, or chronic inflammation
Well tolerated at standard doses. No hormonal interactions known. Start at 250mcg/day. Oral capsule form available for gut-specific applications.
