1.5mg of Retatrutide from a 60mg vial in 3.5mL: how many units?
Answer
Draw 8.8 units on a U-100 insulin syringe. A 60 mg Retatrutide vial reconstituted with 3.5 mL of bacteriostatic water is 17.14 mg/mL, so 1.5 mg is 0.088 mL. That vial holds about 40 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?
- 8.8 units is the U-100 reading, the standard insulin syringe at 100 units to 1 mL. On a U-40 syringe the same 0.088 mL reads 3.5 units.
- How many 1.5 mg doses will this vial give?
- About 40 doses from a 60 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.
