2.4mg of Semaglutide from a 30mg vial in 3.5mL: how many units?

Answer

Draw 28 units on a U-100 insulin syringe. A 30 mg Semaglutide vial reconstituted with 3.5 mL of bacteriostatic water is 8.57 mg/mL, so 2.4 mg is 0.28 mL. That vial holds about 12 doses at this strength.

Doses that would need more than a full 1 mL syringe are omitted. Use less bacteriostatic water for those.

Common questions

What if I used a different amount of water?
Then the unit number changes. Units depend on concentration, not just dose. Run your actual vial size and water volume through the reconstitution calculator rather than copying a number from a chart that assumes 3.5 mL.
Is that on a U-100 or U-40 syringe?
28 units is the U-100 reading, the standard insulin syringe at 100 units to 1 mL. On a U-40 syringe the same 0.28 mL reads 11.2 units.
How many 2.4 mg doses will this vial give?
About 12 doses from a 30 mg vial. Reconstitution volume doesn't change that. It only changes how many units you draw each time.
How long is it good for after mixing?
Refrigerate reconstituted peptide at 36–46°F (2–8°C). Most references give 28–60 days once mixed, depending on the preservative in the bacteriostatic water. Do not freeze it, and inspect for cloudiness or particles before every draw.
