BPC-157
A 15-amino-acid fragment of a stomach protein, studied mostly in rats for gut, tendon, ligament and muscle healing.
Not approved for human use; sold as a research chemical.
Used for
- Tendon, ligament and muscle injuries
- Gut lining: ulcers, IBD, NSAID damage
- Joint pain (used locally)
How it works
In animal work it promotes new blood vessel growth (angiogenesis), interacts with the nitric oxide system and speeds healing of many tissue types. How much of this carries over to people is unknown.
What the research shows
- Almost all evidence comes from one Croatian group’s rat studies: consistently positive, rarely replicated independently.
- A retrospective clinic report of knee injections (BPC-157 alone or with thymosin beta-4) found most patients reported pain relief; no control group.
- A 2-person IV pilot (10 mg, then 20 mg) found no changes in heart, liver, kidney, thyroid or glucose markers.
- Reviews in sports medicine (2025) conclude human efficacy is unproven and call for controlled trials.
Dosing
Dosing isn’t listed on the public site. In the app, each published option is shown with its source (a drug label, a clinical guideline, a trial or community reports) and can be turned into a protocol you review.
Work out the units to draw for your vial →Side effects
- Few reported: injection-site irritation, occasional nausea, dizziness or flushing
Cautions
- It grows blood vessels in animal studies: a theoretical concern with any cancer.
- Prohibited in tested sports (WADA).
- Research-chemical vials have no quality control: purity, dose and sterility vary. Third-party testing helps but is no guarantee.
Storage
Unmixed powder: freezer or fridge, away from light.
Once mixed with bacteriostatic water: fridge; the common rule is to use it within 28 days.
There is no label or published stability data for this one, so treat these as habits, not limits.
Stability once mixed
No stability data. A short chain without obvious weak spots; community reports of 4 weeks or more in the fridge, untested.
Heat, shaking, freezing a mixed vial, light and many needle punctures all speed breakdown. Toss it if it turns cloudy, grows specks or changes color.
