About
Tirzepatide and reconstitution
Tirzepatide is a peptide that activates both the GIP and GLP-1 receptors (a dual agonist).
Research vials of tirzepatide are commonly listed in sizes such as 5, 10, 15, 20 and 30 mg.
To reconstitute, the powder is dissolved in a measured volume of bacteriostatic water. The calculator divides the vial's mass by that volume to get the concentration, then converts any amount into milliliters and U-100 syringe units (100 units = 1 ml).
Questions
Tirzepatide calculator FAQ
How many units is 5 mg of Tirzepatide?
It depends on how much water you add. In a 10 mg vial mixed with 1 ml of bacteriostatic water, the concentration is 10 mg/ml, so 5 mg is 50 units on a U-100 insulin syringe (0.5 ml). Change the vial or water above to get your exact number.
How much bacteriostatic water should I add to a 10 mg Tirzepatide vial?
The math works for any volume. More water lowers the concentration, so each unit holds less and small amounts are easier to measure; less water keeps volumes small. For a 10 mg vial: 1 ml gives 10 mg/ml, so each unit holds 100 mcg; 2 ml gives 5 mg/ml, so each unit holds 50 mcg; 3 ml gives 3.33 mg/ml, so each unit holds 33.3 mcg.
How do you convert Tirzepatide mg to units?
Divide the vial's mg by the ml of water to get the concentration in mg/ml. Then divide the amount you want by that concentration and multiply by 100 to get units on a U-100 syringe. Example: 10 mg in 1 ml is 10 mg/ml, and 5 mg / 10 x 100 = 50 units.
