BPC-157

What it is

BPC-157 is a synthetic peptide consisting of a short chain of fifteen amino acids. The name stands for "Body Protection Compound". Its sequence derives from a fragment described in research on gastric juice. The substance occurs almost exclusively in a research context and is usually supplied as a lyophilised powder labelled research use only.

Mechanism of action

The way BPC-157 works has not been scientifically established. The literature describes several possible points of action, but there is no confirmed, generally accepted mechanism. That uncertainty matters in itself: where a registered medicine has a mechanism documented in detail, that documentation is absent here.

Research status

The vast majority of research into BPC-157 comes from laboratory and animal studies. Controlled clinical research in humans is largely absent, and the few human studies that exist are small or have not been replicated by independent groups. Statements about efficacy or safety in humans are therefore not scientifically supported, however confidently they are made online.

A result in an animal model also says nothing automatic about humans. The page Research & science explains why that step is so large.

Regulatory status

BPC-157 is not approved by the EMA, the FDA or the Dutch CBG. There is no marketing authorisation: the substance is not a medicine. Regulators have explicitly named it as not permitted for human use. In sport, the World Anti-Doping Agency (WADA) prohibits non-approved substances as a category.

What remains unknown

Both the mechanism of action and safety in humans are largely unknown. There is no data on long-term use, interactions, or differences between groups of people. Material circulating outside the regulated chain also has no controlled composition or purity — see Quality & provenance.
