For detailed research information, see our BPC-157 gut health guide.
Basic Questions
What is BPC-157?
BPC-157 is a synthetic peptide consisting of 15 amino acids, derived from a protein found naturally in human gastric juice. Its sequence is:
Gly-Glu-Pro-Pro-Pro-Gly-Lys-Pro-Ala-Asp-Asp-Ala-Gly-Leu-Val
It's called "Body Protection Compound" due to its cytoprotective effects observed in research.
Is BPC-157 natural?
Partially:
- The sequence is derived from a larger natural protein in gastric juice
- BPC-157 itself is a synthetic fragment
- The body doesn't produce BPC-157 as a standalone molecule
- It represents an "active region" of a natural compound
What is BPC-157 researched for?
Primary research areas:
- Wound and tissue healing
- Gastrointestinal protection and healing
- Tendon and ligament repair
- Muscle injury recovery
- Neuroprotection
- Gut-brain axis effects
Is BPC-157 FDA-approved?
No. BPC-157 is:
- Not FDA-approved for any human use
- Sold as a "research chemical" only
- Not evaluated for safety and efficacy by regulatory bodies
- In research/experimental status only
Mechanism Questions
How does BPC-157 work?
BPC-157 works through multiple mechanisms:
Growth Factor Effects:

Both are healing peptides but differ in:
| Factor | BPC-157 | TB-500 |
|---|---|---|
| Origin | Gastric peptide | Thymosin Beta-4 |
| Size | 15 amino acids | Larger fragment |
| Primary mechanism | Growth factors, NO | Cell migration, actin |
| GI benefits | Yes (primary) | No |
| Oral stability | Yes | No |
| Research focus | GI, tendon, general | Cardiac, muscle, systemic |

Does BPC-157 affect hormones?
Based on research:
- Does not appear to directly affect testosterone, estrogen, GH
- May interact with neurotransmitter systems (dopamine, serotonin)
- Not classified as a hormone or hormone-affecting compound
- Mechanism is distinct from hormonal peptides
Administration Questions
How is BPC-157 administered?
Common routes:
- Subcutaneous injection: Most common for research
- Intramuscular injection: Near injury site
- Oral: For GI-focused applications

Can BPC-157 be taken orally?
Yes, uniquely:
- BPC-157 is stable in gastric acid
- Survives digestive process
- Oral use studied for GI healing
- Systemic bioavailability lower than injection
- GI effects don't require systemic absorption
How do you reconstitute BPC-157?
Standard protocol:
- Use bacteriostatic water
- Add water slowly down vial wall
- Swirl gently—never shake
- Calculate concentration
- Store refrigerated
See our detailed reconstitution guide.
What's a typical research protocol?
Note: These are research observations, not recommendations:
- Typical range: 200-500 mcg per day
- Split into 1-2 administrations
- Duration: 2-4 weeks typically studied
- Near injury site or subcutaneous
Effectiveness Questions
Does BPC-157 actually work?
The evidence:
Strong Evidence (Animal Studies):
- Extensive research showing healing effects
- Multiple tissue types studied
- Consistent results across models
- Mechanisms well-characterized
Limited Evidence (Human):
- Very few human clinical trials
- Most human data is anecdotal
- No FDA-approved indication
- Formal efficacy not established
Honest Assessment: Animal research is promising and extensive. Human data is limited to small studies and anecdotal reports. More research is needed.
How long until effects are noticed?
Based on research and reports:
- GI effects: May be noticed within days
- Tissue healing: 2-4 weeks for changes
- Full benefits: May take 4-8 weeks
- Individual variation is significant
Does BPC-157 work for [specific condition]?
Research exists for:
- Gut issues (IBD, ulcers, leaky gut)
- Tendon injuries
- Muscle injuries
- Ligament damage
- Nerve injuries
- Various other conditions
Important caveat: Most research is animal-based. Human clinical data is limited. Efficacy for specific conditions is not proven.
Safety Questions
Is BPC-157 safe?
Current understanding:
