What is BPC-157?
BPC-157 is a synthetic pentadecapeptide (15 amino acids) derived from a gastric juice protein, researched extensively for accelerating tissue healing, gut repair, and tendon recovery. Animal studies demonstrate dose-dependent healing of tendons, ligaments, bones, muscles, and intestinal tissue, along with anti-inflammatory and angiogenic effects. Not FDA-approved; placed on the FDA's 503A prohibited bulk substances list in 2023.
Mechanism of Action
Upregulates VEGF, EGF, and growth factor signaling; promotes angiogenesis; modulates nitric oxide (NO) synthase; activates FAK-paxillin and JAK-STAT pathways
Target: VEGF receptors, NO pathway, FAK-paxillin
Research Indications
Demonstrated acceleration of wound healing and soft tissue repair in research
Research shows beneficial effects on intestinal lining and GI function
Associated with reduced joint inflammation and improved mobility
May support faster recovery from muscle strains and exercise stress

How to Reconstitute & Inject
Use bacteriostatic (BAC) water only. Avoid saline — may cause precipitation. Refrigerate and use within 28 days.
- 1
Remove BPC-157 vial from refrigeration and allow to reach room temperature (15–20 minutes)
- 2
Clean vial top with alcohol swab and allow to air dry completely
- 3
Using a sterile syringe, draw the calculated volume of bacteriostatic water (BAC water)
- 4
Inject BAC water slowly down the side of the vial — do not aim directly at the powder
- 5
Gently swirl in circular motions — DO NOT shake vigorously as this degrades the peptide
- 6
Allow 2–3 minutes for full dissolution — solution should be clear and colorless
- 7
Draw calculated dose into an insulin syringe for subcutaneous injection
- 8
Inject into abdomen, thigh, or upper arm. Rotate injection sites to prevent lipodystrophy
- 9
Store reconstituted solution refrigerated (2–8°C) and use within 28 days
What to Expect
Week 1–2
Initial anti-inflammatory effects begin. Reduced pain and swelling in target area.
Week 2–4
Improved tissue mobility and reduced discomfort. Early healing acceleration.
Week 4–8
Significant recovery milestones. Stronger tissue repair and functional improvement.
Week 8–12
Near-complete healing in many cases. Improved strength and tissue integrity.
Side Effects & Safety
- Generally well-tolerated in research settings
- Mild nausea with higher doses
- Injection site redness or discomfort
- Rare: Dizziness or lightheadedness
- Potential effect on blood pressure (monitor if hypertensive)
BPC-157 is banned from 503A compounding pharmacies. Only available through 503B outsourcing facilities or for research use.
