The most-researched healing peptide in existence. Over 180 preclinical publications document its tissue-protective and regenerative properties — with emerging human data showing remarkable results in women.
BPC-157 is a pentadecapeptide (15 amino acids) derived from a protective protein found in human gastric juice. It promotes angiogenesis (new blood vessel formation), modulates nitric oxide pathways, upregulates growth factor receptors (including VEGF, EGF, and PDGF), and counteracts lesion-induced damage across multiple organ systems including the GI tract, tendons, ligaments, muscles, and the nervous system.
IBS is 2x more common in women than men, making gut-healing peptides disproportionately relevant. A pilot study in women with interstitial cystitis found that 10 of 12 participants experienced 80–100% symptom resolution. BPC-157 is also widely used for post-surgical recovery — relevant for C-sections, hysterectomies, breast surgeries, and cosmetic procedures.
BPC-157 is generally well-tolerated in available human data. Reported side effects are minimal and may include mild nausea, dizziness, and injection site reactions. Oral forms may cause minor GI discomfort initially. Long-term human safety data is limited.

BPC-157 is generally well-tolerated in available human data with minimal reported side effects. It is a Category 1 peptide, meaning it has cleared initial FDA safety review for compounding. However, long-term controlled trial data in women specifically is limited.
BPC-157 has extensive preclinical evidence for gut healing and protection. IBS is 2x more common in women than men. A pilot study showed remarkable results in women with interstitial cystitis, and the gut-healing mechanism is directly relevant to IBS symptoms.
Both routes are used. Oral BPC-157 (often in capsule form) targets the GI tract directly and is preferred for gut-related conditions. Injectable BPC-157 provides systemic effects for tendon, joint, and tissue repair. Your provider can recommend the best route for your goals.
