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.
Preclinical tissue-repair with very limited uncontrolled human data. A randomised Phase 2 hamstring trial is recruiting, but no controlled efficacy result is available yet.
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.
UK status
How you could legitimately come across it here, if at all
The UK position is genuinely unsettled or disputed in our own notes, so we are not going to state it as fact either way.
Evidence strength and UK regulatory status answer different questions.
Heightened caution: this compound carries unresolved regulatory, safety or supply-chain concerns in the UK. Nothing here is a recommendation to use it.
Overview
How it works
Signals your body to grow new blood vessels and send repair cells toward damaged tendons and gut lining.
Signals the body to grow new blood vessels and direct repair cells toward damaged tendon, ligament and gut tissue.
Reported benefits
- Preclinical models report effects on tissue repair, angiogenesis and inflammation
- Small uncontrolled human pilot studies exist, but they do not establish clinical efficacy

Safety & UK access
Dosage
No validated human treatment dose. The published human reports are two tiny uncontrolled pilots by other routes, and the one randomised trial is still recruiting, so no dose-response programme has established a regimen.
Side effects
- Injection site sorenessreported anecdotally; never measured in a controlled trial
- Nauseareported anecdotally; never measured in a controlled trial
- Fatiguereported anecdotally; never measured in a controlled trial
- Adverse events in the published human pilots (12 women, bladder route; 2 adults, intravenous)none reported, but far too few people to detect harm
- Long-term human safetyinsufficient human data

Where it turns up
- Specialist unlicensed supply
- Unregulated online market
- Not routinely available in the UK
Not authorised as a UK medicine, and the regulatory picture is actively contested: our notes record ongoing regulator scrutiny of clinics supplying it. We are not stating whether it can be lawfully supplied to you. Most online supply sits outside any regulated system.
Not MHRA-licensed; some UK private clinics prescribe via the unlicensed-medicines route, but MHRA opened a 2026 inquiry into clinics making unverified claims about this compound
MHRA: the UK regulator that assesses whether a medicine is safe and works before it can be authorised for use here. Something not being MHRA-licensed does not automatically mean it is illegal, and it does not mean it is safe.
This is background information about UK regulation, not advice about what you can or should obtain.
