Tirzepatide Reconstitution Calculator
Reconstitute a 5 mg vial of Tirzepatide with 2 mL of bacteriostatic water for a concentration of 2.50 mg/mL — meaning one unit on a U-100 insulin syringe (0.01 mL) holds 25 mcg. Adjust the inputs below for your own vial and dose.

Frequently Asked Questions
How do I reconstitute Tirzepatide?expand_more
Add 2 mL of bacteriostatic water to the 5 mg Tirzepatide vial for a concentration of 2.50 mg/mL. Inject the water slowly down the vial wall and swirl gently — do not shake.
How many units is a Tirzepatide dose on an insulin syringe?expand_more
At 2.50 mg/mL, one unit on a U-100 syringe (0.01 mL) holds 25 mcg. Divide your target dose in mcg by 25 to get the number of units to draw.
What is the typical Tirzepatide research dose?expand_more
Tirzepatide is typically dosed at 2.5–15 mg once weekly (gradual 4‑week titration steps). in research protocols. See the full titration schedule on the protocol page.
