What it is

BPC-157 is a synthetic chain of 15 amino acids, based on a sequence identified in human gastric juice. The name stands for “Body Protection Compound”. It has been studied for more than three decades, mostly in animal models of injury and gut health. It is not approved as a medicine in any country yet, and human trials remain limited. Supply today is mainly through research-chemical suppliers and compounding clinics.

It is the most-searched peptide outside the weight-loss drugs, roughly 301,000 US searches a month.
