BPC-157 (Body Protection Compound-157) is a synthetic peptide of 15 amino acids whose sequence is derived from a larger protein found in human gastric juice. It has been studied mainly in rodents for its effects on tissue repair. It is a research chemical and has not been approved as a medicine.

What is BPC-157 studied for?

Most published BPC-157 research is preclinical (cells and animals) and explores tendon, ligament, muscle, bone, and gastrointestinal healing, plus possible effects on blood-vessel formation. These findings do not establish that BPC-157 is safe or effective in humans.

Is BPC-157 FDA-approved?

No. BPC-157 is not approved by the U.S. FDA for any use. In 2023 the FDA placed BPC-157 in a category of substances it identified as not suitable for compounding, citing limited safety data. It is sold only as a research chemical.

BPC-157 is not an approved drug or dietary supplement in the United States, so it cannot legally be marketed for human consumption. The World Anti-Doping Agency (WADA) prohibits BPC-157 in sport. Laws vary by country; check local regulations and consult a licensed professional.

What are the reported side effects of BPC-157?

Human safety data are very limited because rigorous human trials are lacking. Reported anecdotes mention injection-site reactions, lightheadedness, and changes in heart rate, but these are not well characterized. Anyone considering it should speak with a licensed clinician first.

How is BPC-157 typically dosed in research settings?

Published animal studies use a wide range of doses normalized to body weight, and these do not translate directly to humans. There is no established, validated human dose. This page does not provide dosing instructions; dosing decisions belong with a licensed clinician.

How is BPC-157 reconstituted?

Lyophilized BPC-157 powder is typically reconstituted with bacteriostatic water by slowly injecting the water down the inside wall of the vial and gently swirling until dissolved. See the reconstitution steps below and our full reconstitution guide.

BPC-157 dosage

BPC-157 comes in 10 mg and 20 mg vials. Pick your vial to see exactly how much bacteriostatic water to add and how many insulin units to draw. Reconstitution math and unit conversions for the 10 mg and 20 mg vials. Any dose figures are community-reported and anecdotal — there is no validated human dose.

Calculate for your vial

Enter the mg on your BPC-157 vial, the bacteriostatic water you added, and your target dose — it works out the exact units to draw on a U-100 insulin syringe, for whatever you personally have.

Check the decimal. A misplaced decimal point here is a 10× dosing error. Re-read every number, and confirm your dose with a licensed clinician before you draw.

Educational only — not a dosing recommendation. This tool does the measurement math; it does not tell you what to take. On a U-100 insulin syringe, 100 units = 1 mL.
