Compound calculator

Tirzepatide Calculator

Use this tirzepatide calculator to convert vial mass, reconstitution volume, and a target amount into concentration, liquid volume, and U-100 syringe units.

For laboratory research only

Your inputs

Set the tirzepatide vial, reconstitution volume, and target amount.

Total tirzepatide mass in this vial, in milligrams.

Use the final solution volume in milliliters.

Target amount unit

Amount in one research sample. 1 mg = 1,000 mcg.

How it works

Tirzepatide dosage calculator

Enter the total tirzepatide mass printed on the vial, the final liquid volume, and the target amount from the research protocol. The calculator returns the concentration, liquid volume, and equivalent markings on a U-100 scale.

This tirzepatide dose calculator performs unit conversion only. It does not select a dosage or research protocol.

For the mixing steps and the water for each vial size, see how to reconstitute tirzepatide.

Find the concentration

Tirzepatide in vial (mg) ÷ final volume (mL)

Enter your values above.

Convert amount to volume

Target amount (mg) ÷ concentration (mg/mL)

Enter your values above.

Read the U-100 equivalent

Sample volume (mL) × 100 = U-100 units

Enter your values above.

2 mL reference table

Tirzepatide units calculator

This tirzepatide reconstitution calculator table assumes a 2 mL final volume. Change the reconstitution volume in the calculator above for a different concentration.

Vial 2.5 mg target 5 mg target 7.5 mg target 10 mg target
10 mg 50 100 150 200
20 mg 25 50 75 100
30 mg 16.67 33.33 50 66.67
60 mg 8.33 16.67 25 33.33

Values are U-100 syringe units. 100 units equals 1 mL.

Common questions

Tirzepatide calculator questions

How many units is 2.5 mg of tirzepatide?

It depends on the concentration. With a 2 mL final volume, 2.5 mg equals 50 units from a 10 mg vial, 25 units from a 20 mg vial, 16.67 units from a 30 mg vial, or 8.33 units from a 60 mg vial on a U-100 scale.

Does the tirzepatide calculator recommend a dosage?

No. It converts a researcher-entered target amount into liquid volume and U-100 units. It does not recommend an amount or protocol.

How does reconstitution volume change tirzepatide units?

Adding more liquid lowers the concentration, so the same target amount occupies more volume and more U-100 units. Adding less liquid raises the concentration.

What does one U-100 unit mean in this calculator?

One U-100 unit is 0.01 mL of liquid. The tirzepatide mass in that volume depends on the vial mass and final reconstitution volume entered.
