The cleanest mechanistic story, and the one most over-sold to athletes
Tendon healing is the application BPC-157 is best known for in fitness communities, and it is also the one with the tightest mechanistic chain: a transected rat Achilles tendon heals faster, isolated tendon cells migrate more, and a defined intracellular pathway (FAK-paxillin) ties the two together. The story is genuinely coherent.
It is also entirely preclinical. Every result in this unit comes from rats or cell culture; the 2025 systematic review found no controlled human tendon-healing trial, and none has reported since. The nearest thing is a placebo-controlled phase 2 in acute hamstring muscle strain, not tendon (NCT07437547), that began recruiting in February 2026 and has published nothing. A strong rat mechanism is exactly the kind of evidence that gets rounded up into a human promise, so we will keep the two firmly apart.
