About These Figures
There is no official or clinical dosing standard for Tirzepatide. The numbers above reflect commonly published research and community protocols, and sources disagree with each other. The amount of water you add changes what each syringe unit means, so always work from your own vial's concentration. See how to reconstitute and the measurement guide.
Frequently Asked Questions
How much bacteriostatic water do I add to a 10 mg Tirzepatide vial?
The sample protocol on this page adds 1 mL of bacteriostatic water to the 10 mg vial. That gives about 10,000 mcg per mL, so 10 units = 1 mg on a 100-unit (1 mL) insulin syringe. Other sources use different volumes, which changes what each syringe unit means, so always recalculate from your own vial.
How many syringe units is 2.5 mg of Tirzepatide?
At the concentration above, 2.5 mg is 25 units on a 100-unit (1 mL) insulin syringe. Use the peptide calculator to check your own numbers.
Is there an official dose for Tirzepatide?
