BPC-157 is a synthetic peptide made of 15 amino acids, a sequence derived from a protein found in gastric juice. The name stands for Body Protection Compound-157. It is studied in laboratory research and supplied for research use only.
Structure and origin
BPC-157 is a pentadecapeptide, which simply means a peptide of 15 amino acids. Its sequence is based on a fragment of a protein that occurs naturally in gastric juice. The research compound itself is made synthetically through solid-phase peptide synthesis.
How it is studied
In the laboratory, BPC-157 is studied in research related to tissue and connective tissue. As with any research peptide, it is a tool for investigation, not a therapeutic, and it is not approved or intended for human use.

Every Axis compound is third-party tested to 99.4%+ purity, with a certificate of analysis on every batch.
What to look for
Because peptide identity and purity cannot be judged by eye, a research-grade BPC-157 should come with a batch-specific certificate of analysis. It is also frequently studied alongside TB-500, a pairing you will see offered as a blend.
