A synthetic 15-amino-acid peptide described as a partial sequence of a protein from gastric juice, studied widely in animal models for tendon, muscle, and gut-lining repair. The preclinical signal is broad but comes largely from one research group — controlled human data is the missing piece.
How it works
In animal work, BPC-157 appears to promote healing by encouraging new blood-vessel growth and modulating growth-factor and nitric-oxide signaling at injury sites. The parent 'Body Protection Compound' protein is not well characterized in protein databases, so the peptide is best described as a synthetic fragment.
Sequence: GEPPPGKPADDAGLVA 15-residue synthetic peptide (note the three consecutive prolines). No UniProt entry exists for the isolated peptide.
What it's studied for
One claim per card, each with its own tier and source. Tiers 1 and 2 are human data. Tiers 3 and 4 are not yet.

Safety & limitations
No long-term human safety data exist; the only human exposure of note is a two-person intravenous safety pilot. Because supply is grey-market, identity and purity are not assured.

Not approved for human use in any major jurisdiction. A Phase 2 trial for acute hamstring injury is registered but has no efficacy results yet.

Does BPC-157 heal injuries in people?
That hasn't been shown. The healing evidence is from rodent and in-vitro studies, mostly from a single research group. No completed placebo-controlled human efficacy trial exists yet.
