How many units is 1.7 mg of semaglutide?
It depends on exactly one thing: the concentration printed on your vial. Here it is
at the 4 strengths compounded semaglutide usually comes in, and drawn on the barrel.
At 1 mg/mL, 1.7 mg is 170 units — more than one syringe holds. At 2.5 mg/mL, 1.7 mg is 68 units (0.68 mL). At 5 mg/mL, 1.7 mg is 34 units (0.34 mL). At 10 mg/mL, 1.7 mg is 17 units (0.17 mL).
What that looks like on the barrel
170 units — more than one syringe holds. 1.7 mL: that's two draws, or a stronger vial.
1 mg/mL → 170 units
2.5 mg/mL → 68 units on a 100-unit syringe
5 mg/mL → 34 units on a 50-unit syringe
10 mg/mL → 17 units on a 30-unit syringe
About this dose
Weeks 13–16. Wegovy only — Ozempic goes from 1 mg to 2 mg instead (2 mg is 80 units at 2.5 mg/mL, 40
at 5, 20 at 10). At 1 mg/mL, 1.7 mg is 170 units and doesn't fit in a syringe; this is the step
where a 1 mg/mL vial stops working. At 2.5 mg/mL it's 68 units on a 100-unit barrel.
Check it yourself
The whole sum is units = dose ÷ concentration × 100. For this dose at
2.5 mg/mL: 1.7 ÷ 2.5 × 100 = 68. If your
vial isn't marked in mg/mL, the concentration is the vial's total milligrams divided by the water
that went in — a 5 mg vial with 2 mL of water is 2.5 mg/mL.
