Reconstitution math and U-100 syringe units for every titration step
Semaglutide is dosed weekly with a four-step titration that starts at 0.25 mg and climbs to 2.4 mg as tolerated. The dose volume changes every step, and the math depends on how much bacteriostatic water you used to reconstitute the vial. This calculator handles both — enter your vial strength, water volume, and the dose your provider prescribed, and the visual U-100 syringe meter draws the exact fill line.

Interactive Semaglutide reconstitution and dose calculator
Worked example — Semaglutide 0.25 mg starting dose
A typical reconstitution and dose calculation for Semaglutide, with every variable spelled out. The calculator above runs the same math live as you change inputs.
- Vial strength
- 5 mg
- Bacteriostatic water
- 3 mL
- Concentration
- 1.67 mg/mL
- Dose volume
- 0.15 mL · 15 units
A 5 mg vial reconstituted with 3 mL of bacteriostatic water yields a concentration of 1.67 mg/mL. The 0.25 mg starting dose works out to 0.15 mL — 15 units on a U-100 insulin syringe. As you titrate up to 0.5 mg, 1.0 mg, 1.7 mg, and 2.4 mg, the unit count scales proportionally: 30, 60, 102, and 144 units respectively.
