10 Units of Retatrutide Is How Many mg?

It depends on the concentration. Here is what 10 units on a U-100 syringe holds at every common Retatrutide mix, with the math.

Medically reviewed by Juan Pablo Frías, MD · 3 Oct 2026 · DisclosureGLP-1 / GIP / glucagon triple agonistUpdated 3 Oct 2026

10 units: 0.10 mL; U-100 syringe
At 5 mg/mL: 0.5 mg; 10 mg vial + 2 mL
At 10 mg/mL: 1 mg; 20 mg vial + 2 mL

The short answer

10 units on a U-100 insulin syringe is 0.10 mL. How many mg that holds depends on how concentrated the solution is: mg = mL × mg per mL. For example, 10 units of a 5 mg/mL solution is 0.5 mg.

10 units at each concentration

Concentrations you get from the vial sizes Retatrutide is sold in, mixed with 1 to 3 mL of bacteriostatic water.

How to work it out

1. Concentration = vial mg ÷ mL of water added (a 10 mg vial + 2 mL = 5 mg/mL). 2. Volume = units ÷ 100 (10 units = 0.10 mL). 3. mg = volume × concentration.

Common questions

10 units of Retatrutide is how many mg?

On a U-100 syringe, 10 units is 0.10 mL. Multiply by the concentration: at 5 mg/mL that is 0.5 mg; at 10 mg/mL it is 1 mg. Check the concentration on your vial or prescription label.

How many mL is 10 units?

0.10 mL. A U-100 insulin syringe holds 100 units per mL, so units ÷ 100 = mL.

Is 10 units of Retatrutide a normal dose?

Units measure volume, not dose. The same number of units holds a different amount of drug at each concentration, which is why this page does not judge doses.
