How to use this calculator
- Set your dose. The amount you want per injection (mcg or mg).
- Enter vial strength. Total peptide in the vial (mg).
- Add water volume. Bacteriostatic water used (mL).
- 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.
