BPC-157
BPC-157 is a synthetic peptide studied mostly in animals for tissue healing. It is not FDA-approved, there are almost no human trials, and it is banned in sport.
What it is
A 15-amino-acid peptide based on a fragment of a protein found in gastric juice.
What the evidence shows
In people
Very limited. A handful of small pilot reports exist, with no large randomized controlled trials.
In animals and labs
Many rodent studies report effects on tendon, muscle, and gut healing. Much of this work comes from a small number of research groups and has not been confirmed in people.
Legal status
Not approved for any use. The FDA has listed it among substances raising potential safety concerns for compounding, and its compounding status has been under review. Selling it as "research only" does not make human use legal.
Dosing
There is no established human dose
No regulator has approved a dose for human use. Numbers shared online come from animal studies, small early trials, or seller protocols, and none of them have been shown to be safe or effective. BOTH does not publish dosing, mixing, or injection instructions for unapproved compounds.
Known risks
- Unknown human safety profile
- Theoretical concern about promoting blood vessel growth, which matters for people with cancer
- Injection-site infection and contamination from non-sterile products
- Products may not contain what the label says
