Common BPC-157 vial sizes
BPC-157 is commonly supplied as 5, 10 mg vials. A common starting point is 10 mg reconstituted with 2 mL of bacteriostatic water, which gives 5 mg/mL.
How to reconstitute BPC-157
- Add 2 mL of bacteriostatic water (or your chosen volume) slowly down the side of the vial.
- Swirl gently until the solution is clear. Do not shake.

- Draw to the exact unit mark it highlights on the syringe.
Example dose in units
At 5 mg/mL, a 250 mcg dose of BPC-157 is about 5 units on a U-100 insulin syringe. Change any value above to match your own vial.
