What it is
BPC-157 is a lab-made chain of 15 amino acids based on a protein found in stomach juice. It is popular online for injuries, gut problems and recovery.
In animal studies it appears to support blood vessel growth and tissue repair and to protect the stomach lining. How it works in people is not well understood.
US regulatory status
Not FDA-approved. In April 2026 the FDA removed it from its Category 2 list of compounding substances with safety concerns, and in July 2026 an FDA advisory committee voted 8-6 to recommend adding it to the list of substances pharmacies may compound. As of October 2026 that recommendation is not final: it still needs FDA rulemaking, a proposed interim access policy was under White House review, and it remains an unapproved drug.
What the research shows
Most BPC-157 research is in rats and mice, where it showed faster healing of tendons, muscles and the gut. Human data are very limited: a few small studies and case reports, and a 2025 systematic review in sports medicine found the human evidence too weak to support clinical use.

Questions to ask your provider
- What does the research really show about BPC-157 in humans?
- Are there FDA-approved treatments for my goal that have stronger evidence?
- What are the risks of products labeled "research use only," and how would I know what is really in them?
