Compound overview
An experimental peptide studied across tissue-repair models.
BPC-157 is a synthetic pentadecapeptide described in scientific literature as a partial sequence of a protective compound associated with human gastric juice.
It has been investigated primarily in cellular and animal models involving tendons, ligaments, muscles, skin, blood vessels, and gastrointestinal tissues. Popular claims about human recovery substantially exceed the available clinical evidence.
Mechanism under study
Proposed repair and vascular signaling pathways
Its complete mechanism has not been established. Preclinical studies describe effects involving cell migration, angiogenic signaling, and nitric-oxide pathways, but these findings have not been validated as therapeutic effects in controlled human trials.
Vascular signaling
Cell and animal experiments report effects involving VEGF, ERK1/2, angiogenesis, and microvascular responses.
Nitric-oxide pathways
Experimental studies suggest interactions with endothelial nitric-oxide signaling and vascular tone.
These proposed mechanisms come primarily from laboratory and animal research and should not be interpreted as proven human therapeutic mechanisms.
Current research areas
Questions under investigation
- Tendon and ligament repair
- Muscle and myotendinous-junction healing
- Wound healing and angiogenesis
- Gastrointestinal tissue protection
- Nitric-oxide and microvascular signaling
Evidence summary
Reported preclinical findings
- Tendon healing: Rat studies report improved structural, biomechanical, and functional outcomes after experimental tendon injury.
- Ligament repair: Preclinical studies report improved healing following surgically induced ligament injuries in rats.
- Muscle recovery: Animal models have examined muscle, muscle-to-bone, and myotendinous-junction repair.
- Wound response: Cell and animal studies report effects on fibroblast migration, vascular growth, granulation tissue, and wound closure.
- Gastrointestinal protection: Rodent studies report protective or reparative effects in experimental gastrointestinal injuries.
These preclinical findings require confirmation through controlled human research.
