How to use this calculator

  1. Set your dose. The amount you want per injection (mcg or mg).
  2. Enter vial strength. Total peptide in the vial (mg).
  3. Add water volume. Bacteriostatic water used (mL).
  4. Read results. Use the draw volume and U-100 units for repeatable measurement.
Worked example: a 5 mg vial in 3 mL water gives 1.667 mg/mL. A 250 mcg dose is 0.25 mg. 0.25 / 1.667 = 0.150 mL = 15 units on a U-100 syringe.
