What it is and why people ask
A lab-made peptide
A peptide joins protein building blocks in a small chain.
BPC-157 has fifteen of these blocks and is made in a lab.
It was designed from part of a protein reported in juice from the human stomach.
That origin does not show that using it is safe.
Why people ask about healing
Animal studies have reported better healing in damaged tendons, which connect muscles to bones, and other body tissues.
Those animal findings sit behind many of the claims about recovery.
They do not establish that the same results happen in people.
Read the government’s reviewThe human evidence is small
The Food and Drug Administration, or FDA, reviewed the small human-study record available in September 2026.
It found five human studies, with roughly eighty people receiving BPC-157 altogether.
What was compared?
Only two studies had a group for comparison; neither was available as a full published paper.
A comparison group helps test whether the treatment, rather than something else, explains a change.
A study still awaiting results
A study of injuries to the hamstring muscles, at the back of the thigh, is listed in the government’s study records. As of September 2026, it had not reported results.
The listing gives the study’s plan and progress, not proof that the treatment helps.
