About BPC-157
Not FDA-approved as a finished product. Available as a compounded preparation from licensed 503A/503B pharmacies in some U.S. states. Regulatory status evolving.
BPC-157 is a pentadecapeptide — meaning a 15-amino-acid chain — that was isolated as a fragment of Body Protection Compound, a naturally occurring peptide in human gastric juice. Preclinical research has explored BPC-157's effects on gastric ulcer healing, tendon repair, ligament healing, and soft-tissue injury recovery in animal models. Human pharmacokinetic data is limited; the 4-hour half-life cited in this app is based on rodent subcutaneous PK studies.
Users tracking BPC-157 in the My Pep Calc app commonly log 200–500 mcg per injection, twice daily, either subcutaneously near a site of interest for localized protocols or abdominally for systemic protocols. BPC-157 is not an FDA-approved drug; in the United States it is typically sourced as a compounded preparation from licensed 503A/503B pharmacies, where legal, or as a research chemical. Regulatory status varies by jurisdiction and users are responsible for compliance with applicable law.
Frequently asked questions
- How long does BPC-157 stay in the body?
- Preclinical PK studies in rodents suggest a subcutaneous half-life of approximately 4 hours, which is why many users log BPC-157 twice daily (morning and evening). Human PK data is limited, so this value is treated as an estimate.
- What's a typical vial size and reconstitution volume?
- Users commonly log 5 mg vials reconstituted with 2 mL of bacteriostatic water, giving a concentration of 2,500 mcg/mL. At a 250 mcg dose, that's 0.10 mL — or 10 units on a U-100 insulin syringe. Use the calculator above for your specific numbers.
- Is BPC-157 legal?
- BPC-157 is not an FDA-approved drug. Its legal status as a research chemical or compounded preparation varies by state and country. You are responsible for knowing and complying with applicable law. This app does not sell, source, or verify compounds.
