5 mg × 1,000 = 5,000 mcg, divided by 2 mL = 2,500 mcg/mL. One unit on a U-100 syringe is 0.01 mL, so it holds 25 mcg.
Arithmetic only. This tool does not suggest an amount of Tirzepatide to use, and nothing on this page is a recommendation. What amounts were given in published studies, and to whom, is set out on the Tirzepatide dosage page.
