Tirzepatide Dose Calculator
Work out exactly how many insulin-syringe units your weekly tirzepatide dose is. Enter the vial strength, how much bacteriostatic water you added, and the dose you plan to take — the calculator returns the mg/ml concentration, volume per dose, syringe units, and how many doses the vial will last.

Common tirzepatide mixing ratios
| Mix | Concentration | 2.5 mg dose |
|---|---|---|
| 10 mg vial + 2 ml water | 5 mg/ml | 50 units |
| 15 mg vial + 3 ml water | 5 mg/ml | 50 units |
| 30 mg vial + 3 ml water | 10 mg/ml | 25 units |
Units assume a standard U-100 insulin syringe, where 100 units = 1 ml.
How the calculation works
- Concentration (mg/ml) = milligrams in the vial ÷ millilitres of water added.
- Volume per dose (ml) = your dose in mg ÷ concentration.
- Syringe units = volume per dose × 100 on a U-100 insulin syringe.
Tirzepatide is taken once weekly, so one vial usually covers several weeks. Always follow the dosing your prescriber has given you, and double-check your own numbers before drawing up.
