BPC-157 typically ships as a 5 mg or 10 mg lyophilized vial. Enter the vial size, the bacteriostatic water you add and your target amount in micrograms — the live syringe shows exactly where to pull the plunger.
Common setup
A 5 mg vial in 2 mL of BAC water gives 2500 mcg/mL, so a 250 mcg draw is 0.1 mL = 10 units on a U-100 syringe. Add more water for a larger, easier-to-read draw.
