BPC-157
Also known as: Body Protection Compound 157
Synthetic peptide derived from gastric juice protein
Mechanism of Action
May promote angiogenesis, tissue healing, and modulate nitric oxide pathways. Research is primarily preclinical.
BPC-157 (Body Protection Compound 157) is a synthetic peptide derived from gastric juice protein with 56 research articles and 14 clinical trials indexed — yet it remains unapproved for human use by the FDA. Preclinical data suggests it may promote angiogenesis, tissue healing, and nitric oxide pathway modulation. Its use is banned in professional sports despite growing clinical and athletic interest, according to a 2025 systematic review in HSS Journal.
Reported Outcomes
Clinical grade reflects published research; Community grade reflects user reports (n=1,194).
Improvements in skin quality, firmness, and appearance
Joint pain relief and mobility improvements
A retrospective observation of human patients indicated that intra-articular injection of BPC-157 provided relief for chronic knee pain in the majority of subjects.
Accelerated recovery from injuries and surgery
Systematic reviews of preclinical studies demonstrate BPC-157 promotes recovery in muscle, tendon, ligament, and bone injuries. It accelerates functional recovery in spinal cord injury and heals corneal abrasions.
Effects on sleep quality
Reduction in inflammation and swelling
The peptide reduces inflammatory cytokines and demonstrates anti-inflammatory effects in incisional pain models and NSAID-induced toxicity.
Tendon and ligament repair and health
BPC-157 therapy facilitates the reattachment of muscle to bone and heals transected myotendinous junctions in rats, restoring functional biomechanics.
Wound healing and scar improvement
BPC-157 accelerates the healing of skin wounds, deep burns, and complex fistulas (e.g., vesicovaginal) in rats, often closing defects that fail to heal spontaneously.
Anti-aging and regenerative effects
Changes in energy and fatigue levels
Effects on mood and cognitive function
In rat models, BPC-157 counteracts cognitive dysfunction, anhedonia, and social withdrawal resembling schizophrenia symptoms. It also demonstrates anxiolytic and antidepressant effects.
Muscle recovery and repair from exercise or injury
BPC-157 restores myotendinous junctions and promotes muscle reattachment in rats. It also counteracts muscle wasting (cachexia) associated with tumor models.
Gut lining repair and digestive health
Extensive preclinical evidence shows BPC-157 heals gastric ulcers, intestinal anastomoses, and ischemic colitis. It counteracts lesions from alcohol and NSAIDs (celecoxib, aspirin) and rescues sphincter function.
Effects on hair growth and quality
