BPC-157
Body Protection Compound 157
BPC-157 (Body Protection Compound 157) is a synthetic pentadecapeptide derived from a partial sequence of human gastric juice protein, consisting of 15 amino acids. It is primarily used for its potent tissue-healing and regenerative properties, with research demonstrating accelerated recovery of tendons, ligaments, muscles, and gut tissue. In the research and biohacking community, it is widely used for injury recovery, gut healing (particularly leaky gut and IBD-related conditions), and neuroprotection.
Mechanism of Action
BPC-157 exerts its effects primarily by upregulating growth hormone receptor expression and activating the nitric oxide (NO) system, which promotes angiogenesis and tissue perfusion at injury sites. It also modulates the VEGF (vascular endothelial growth factor) pathway, accelerating formation of granulation tissue and collagen synthesis in damaged tendons and ligaments. Additionally, BPC-157 interacts with the dopaminergic and serotonergic systems in the CNS and appears to stabilize gut mucosal integrity by promoting expression of cytoprotective proteins including HSP70.

Dosing Protocols
Preferably in the morning or close to the site of injury (subcutaneous or intramuscular)
Cycle: 4-6 weeks on, 2-4 weeks off
Subcutaneous injection near the injury site is the most studied and widely used protocol. Reconstitute lyophilized powder with bacteriostatic water. Use insulin syringes for subcutaneous administration. Intramuscular injection is also practiced but subcutaneous is generally preferred for ease and comfort.
On an empty stomach, 30 minutes before eating
Cycle: 4-8 weeks on, 2-4 weeks off
Oral dosing is particularly preferred for gastrointestinal conditions (IBD, leaky gut, ulcers) as the peptide acts locally along the GI tract. Bioavailability via oral route is lower than injection but evidence suggests meaningful systemic effects still occur. Higher doses are used orally to compensate for reduced absorption. Capsule or liquid forms are available from peptide vendors.
Safety & Side Effects
BPC-157 has demonstrated a favorable short-term safety profile in animal studies and has not produced significant systemic toxicity even at supraphysiological doses in rodent models; however, human clinical trial data remains limited and largely unpublished. The compound is unscheduled in most jurisdictions but is not approved for human use by the FDA or EMA, is banned by WADA in competitive sports, and individuals with a personal or family history of cancer should exercise caution given theoretical pro-angiogenic risks.
Possible Side Effects
- !Nausea and mild gastrointestinal discomfort, particularly at higher oral doses
- !Injection site redness, mild swelling, or bruising (transient, typically resolves within 24 hours)
- !Dizziness or lightheadedness, likely related to nitric oxide-mediated vasodilation
- !Transient fatigue or lethargy, especially during the first 1-2 weeks of use
- !Mild headache reported by a subset of users, possibly related to altered serotonergic signaling
- !Theoretical promotion of existing tumor growth via VEGF/angiogenesis pathways (preclinical concern, not confirmed in humans)
- !Hypotension at higher doses due to NO system activation - rare but notable
Interactions
- -May potentiate the effects of NSAIDs (e.g., ibuprofen, aspirin) on GI mucosal protection - generally considered a beneficial interaction for gut health
- -Additive blood pressure lowering effects possible when combined with antihypertensive medications due to nitric oxide system activation - monitor blood pressure closely
- -May enhance wound healing and anticoagulant effects when co-administered with blood thinners (warfarin, heparin) - use with caution and monitor INR
- -Potential synergistic tissue-repair effects when stacked with TB-500 (Thymosin Beta-4) - a common combination in the research community, though combined safety data is lacking
- -May modulate dopamine and serotonin pathways - theoretical interaction risk with SSRIs, SNRIs, and dopaminergic medications, though clinical significance is unknown
Cost & Where to Buy
Lyophilized BPC-157 powder for injection typically costs $30-80 per 5mg vial from reputable peptide research vendors, with a 5mg vial lasting approximately 10-20 days at standard doses. Oral capsule formulations tend to cost more per equivalent dose. Price varies significantly by vendor purity, third-party testing, and quantity purchased. Bacteriostatic water and insulin syringes add a small one-time cost. Only purchase from vendors providing COA (certificate of analysis) with HPLC purity verification.
