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

Amount: 6 mg
At 5 mg/mL: 120 units; e.g. 10 mg vial + 2 mL
At 10 mg/mL: 60 units; e.g. 20 mg vial + 2 mL
Syringe: U-100; 100 units = 1 mL

6 mg in units at common mixes

Units on a U-100 syringe (100 units = 1 mL) for a 6 mg amount, by vial size and water added. Concentration = vial mg ÷ mL of water; units = dose ÷ concentration × 100.

How the math works

Concentration is the vial's milligrams divided by the water you add. Volume to draw is your dose divided by that concentration. On a U-100 syringe, 1 mL is 100 units, so units = mL × 100.

10 mg ÷ 2 mL = 5 mg/mL
6 mg ÷ 5 mg/mL = 1.2 mL
1.2 mL × 100 = 120 units

120 units · 1.2 mL · 6 mg from 10 mg + 2 mL

Math only. The amounts in these tables are reference values for the arithmetic, not dose recommendations.

Common questions

How many units is 6 mg of Semaglutide?

It depends on the concentration. With a 10 mg vial and 2 mL of water (5 mg/mL), 6 mg is 120 units on a U-100 syringe. The table shows other mixes.

Is 6 mg a recommended dose of Semaglutide?

This page is math only. It converts an amount into syringe units and does not recommend a dose. See the dosage page for what studies used.
