Tirzepatide Dosage Calculator
Calculate Tirzepatide peptide dosing, reconstitution volume, and syringe draw units. This calculator performs math conversions only — Tirzepatide is not FDA-approved. It does not recommend doses for unsupervised use.

How Reconstitution Works
- Determine concentration: Divide peptide amount by water volume (e.g., 5 mg ÷ 2 mL = 2.5 mg/mL)
- Calculate draw volume: Divide your dose by concentration
- Convert to syringe units: Multiply mL by 100 for U-100 syringes
- Verify syringe capacity: Ensure the draw volume fits your syringe
Example Calculation
Vial: 5 mg Tirzepatide
Water: 2 mL bacteriostatic
Dose: 2.5 mg
Syringe: 100U (1 mL)
Concentration: 5 mg ÷ 2 mL = 2.5 mg/mL
Draw volume: See calculator output
