BPC-157 (Body Protection Compound-157) is a synthetic pentadecapeptide derived from a protective protein found in human gastric juice. It consists of 15 amino acids and has been studied in animal models for its effects on tissue repair, gut health, tendon healing, and neuroprotection. It is not FDA-approved for human use.
BPC-157 exists in a regulatory gray area in the United States. It is not FDA-approved as a drug and cannot be legally marketed for human consumption. It is sold as a research chemical for laboratory use only. The FDA issued a warning letter in 2022 regarding compounded BPC-157 preparations. See our full legal guide for details.
Based on animal research, the most commonly referenced dose range is 250–500 mcg per day, administered subcutaneously or intramuscularly. Some protocols use oral administration for gut-specific applications. No human clinical trials have established a safe or effective dose.
In animal studies, effects on tissue repair were observed within 1–2 weeks of consistent administration. Anecdotal reports from researchers suggest noticeable effects on gut symptoms within 1–4 weeks. Individual response varies significantly.
BPC-157 appears to work through multiple pathways: upregulation of growth hormone receptors, stimulation of angiogenesis (new blood vessel formation), modulation of the nitric oxide system, activation of the FAK-paxillin pathway for cell migration, and interaction with the dopaminergic and serotonergic systems.
BPC-157 and TB-500 have different primary mechanisms. BPC-157 primarily works via receptor upregulation and angiogenesis, while TB-500 (Thymosin Beta-4) works through G-actin sequestration and cytoskeletal regulation. They are often stacked together for synergistic tissue repair effects.
