Tissue Repair
BPC-157
People use this hoping it speeds up healing in tendons, ligaments and the gut — the idea comes from a protein your stomach makes naturally. The catch: it's only ever been tested in animals. Nobody knows the right human dose, or whether it even works the same way in a person.
Tendon and gut repair — the most-discussed recovery compound, but with zero completed human dose-response trials.
How well studied
Tier Guide: A = Well studied, B = Some good studies, C = Early evidence & D = Barely studied
Mostly animal studies or very small early trials in humans. We don't really know yet how it behaves in people.
Heightened caution: this compound carries unresolved regulatory, safety or supply-chain concerns in the UK. Nothing here is a recommendation to use it.

Getting it in the UK
Still legal for a doctor to prescribe, but it hasn't been officially approved for this specific use. Uncommon, and comes down to a specialist's own judgement.
MHRA: the UK government body that checks a medicine is safe and actually works before doctors are allowed to prescribe it.
