At 5 mg/mL, every 10 units on a U-100 syringe is 0.5 mg of semaglutide.

0.25 mg is 5 units, and 0.5 mg is 10 units. Use the calculator for any other amount.

Notes for 5 mg/mL

Check the strength on every new vial

Units only mean something for one strength. If 20 units was 0.5 mg on a 2.5 mg/mL vial, the same 20 units from a 5 mg/mL vial is 1 mg, not 0.5 mg.

In July 2024 the FDA warned about dosing errors with compounded semaglutide, including mix-ups between mg, mL and units (FDA alert). The same math applies to any vial.
