Notes for 30 mg/mL

At 30 mg/mL, 1 unit is 0.3 mg and 10 units is 3 mg.
Listed doses up to 15 mg fit a 0.5 mL (50-unit) syringe.
Listed doses up to 7.5 mg fit a 0.3 mL (30-unit) syringe.

Check the strength on every new vial

Units only mean something for one strength. If 50 units was 5 mg on a 10 mg/mL vial, the same 50 units from a 30 mg/mL vial is 15 mg, not 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.
