BPC-157
A peptide. 15 amino acids. Almost all the famous papers are in rats. Research only. Not a protocol.
Simple words
Your stomach juice has long proteins. Researchers cut out a 15-bead stretch and named it BPC-157. BPC means body protection compound. That is a lab nickname, not a promise.
People buy it for tendons, gut lining, and injuries that will not quit. The animal papers are why.
What it is
A synthetic copy of that 15-amino-acid stretch. It is a peptide. It is not FDA-approved as a medicine.
What researchers studied
Predrag Sikiric’s group in Zagreb published most of the rat work: stomach ulcers, torn tendons, gut leaks, blood-vessel injuries. In those models, animals often healed faster. The same lab wrote many of the reviews.
Independent, large, placebo-controlled human trials for “fix my tendon” are not what that pile of papers is. If someone says “proven in humans,” ask for the trial, not a rat photo.

What this is not
Not a human-proven tendon drug. Not a blend. This page does not tell you how much to take.
