The short answer is: not directly, but it can help in other important ways.
What BPC 157 Actually Does
BPC 157 is a peptide that promotes healing and reduces inflammation. It works primarily by:
- Speeding up tissue repair in muscles, tendons, and ligaments
- Reducing inflammation after injury or intense exercise
- Protecting gastrointestinal tissue from damage
- Improving blood flow to damaged areas
The Connection to Muscle Growth
BPC 157 doesn't build muscle directly like steroids or growth hormone. Instead, it creates better conditions for muscle growth by:
- Helping you recover faster between workouts
- Reducing your risk of injuries that stop training
- Potentially allowing you to train more frequently and intensely
Think of it as removing obstacles rather than directly building muscle.

What Research Shows
Studies on BPC 157 focus mainly on its healing properties. Scientists have found it helps with:
- Tendon and ligament repair
- Muscle tear recovery
- Gut health improvement
- Joint pain reduction
However, no studies prove it directly increases muscle size or strength in humans.
Should You Use It for Muscle Growth?
If you're looking specifically for muscle growth, best peptides for muscle growth like growth hormone secretagogues might work better.
BPC 157 makes more sense if you:
- Are recovering from an injury
- Experience joint pain that limits training
- Need faster recovery between intense workouts
- Want to reduce inflammation that slows your progress
Safety Considerations
While BPC 157 appears relatively safe, research is still limited on long-term effects. Some people wonder whether BPC 157 may affect the liver, brain, or heart with extended use.
