BPC-157 is a synthetic 15-amino-acid peptide based on a fragment of a protein found in gastric juice. It is not FDA approved, and most published research is in animals.
Also known as: Body Protection Compound 157.
Powder vials are usually labeled 5 mg or 10 mg.
Here is the math for a 5 mg vial mixed with 2 mL of bacteriostatic water, drawing 250 mcg with a U-100 insulin syringe (1 mL = 100 units).
5 mg ÷ 2 mL = 2.5 mg/mL250 mcg ÷ 2.5 mg/mL = 0.1 mL0.1 mL × 100 = 10 units| Amount | Volume | U-100 syringe |
|---|---|---|
| 125 mcg | 0.05 mL | 5 units |
| 250 mcg | 0.1 mL | 10 units |
| 500 mcg | 0.2 mL | 20 units |
Adding more water doesn't change how much BPC-157 is in the vial. It only spreads it over more liquid, so each draw is bigger and easier to read.
| Water added | Concentration | Volume | U-100 syringe |
|---|---|---|---|
| 1 mL | 5 mg/mL | 0.05 mL | 5 units |
| 2 mL | 2.5 mg/mL | 0.1 mL | 10 units |
| 3 mL | 1.67 mg/mL | 0.15 mL | 15 units |
| 5 mL | 1 mg/mL | 0.25 mL | 25 units |
For any other vial size or amount, the free peptide reconstitution calculator works backwards from the amount you want and suggests a water volume that lands on a clean syringe mark.
There is no published human data for BPC-157 injected under the skin, so we do not list a half-life. Studies in rats and dogs (He 2022), given into a vein or muscle, measured a half-life under 30 minutes, and a small 2-person IV pilot was reported to show the same. No study has measured it under the skin in any species. The level curve in the app is a modeling estimate based on those animal studies, not a measured human value.
