BPC-157: Dosage, Protocol, and Research Guide
Body Protection Compound derived from a gastric juice protein; healing and anti-inflammatory effects have been reported in animal studies
Mechanism
Stable gastric pentadecapeptide that promotes angiogenesis through VEGF upregulation, increases growth factor expression (EGF, TGF-β), modulates nitric oxide system, and accelerates tendon/ligament fibroblast proliferation and migration.
BPC-157 reconstitution example (educational math)
This worked example shows how vial size, BAC water volume, and target dose translate to syringe units on a standard U-100 insulin syringe (100 units = 1 mL). For research and education only — not medical advice.
Setup: 5 mg vial + 2 mL bacteriostatic (BAC) water → 2.5 mg/mL (2,500 mcg/mL)
| Target dose | Injection volume | U-100 syringe |
|---|---|---|
| 250 mcg | 0.1 mL | 10 units |
| 500 mcg | 0.2 mL | 20 units |
Refrigerate the reconstituted vial and use within 30 days.

Protocol notes
- In animal and cell studies, stimulates new blood vessel growth (angiogenesis)
- In cell and animal studies, boosts fibroblast activity and collagen production
- In animal studies, accelerated healing of wounds, ligaments, tendons and muscles
- In animal studies, protected the gut lining and ulcer healing
- Nerve regeneration has been reported in animal studies only
- Also available in oral capsule form for GI conditions
- Human safety and efficacy have not been established; most data come from animal studies

Frequently asked questions
Does BPC-157 need to be refrigerated?
Yes. Store reconstituted BPC-157 refrigerated and use within 30 days. Do not freeze after reconstitution.
What is BPC-157 used for in research?
Research has focused on tissue healing, wound recovery, ligament and tendon repair, gastrointestinal health, and nerve regeneration. For research purposes only — consult a physician.
What are the reported side effects of BPC-157?
Almost all available safety data come from animal studies, which reported few side effects. Human safety has not been established. Individual responses vary — consult a healthcare provider.
Is BPC-157 legal?
BPC-157 is not FDA-approved as a pharmaceutical drug and is available for research purposes only. Regulatory status varies by country. Consult a legal and medical professional in your jurisdiction.
How long until BPC-157 starts working?
In preclinical studies, subjects often showed measurable tissue response within 1–2 weeks. Real-world anecdotal reports vary widely — some users report benefit within days, others need 3–4 weeks. Track dose and response with a protocol tracker for objective data.
Can BPC-157 be stacked with TB-500?
BPC-157 + TB-500 is the most commonly reported recovery stack in community protocols. Typical reported split: BPC-157 250mcg twice daily SubQ, TB-500 2.5mg weekly IM. This is community practice, not medical advice.
Oral vs. injectable BPC-157?
Most peer-reviewed research used injectable BPC-157 (SubQ or IM). Oral forms exist but have less published evidence. Consult research references and a physician when choosing administration route.
