Question 1

How many units is a 250 mcg dose of Semaglutide (2mg vial, 3ml diluent)?

Accepted Answer

37.5 units on a standard U-100 insulin syringe (0.375 ml). Mixing a 2mg vial of Semaglutide with 3ml of bacteriostatic water gives a concentration of 0.67 mg/ml. On a U-100 insulin syringe that means: 250 mcg = 37.5 units · 500 mcg = 75 units · 1 mg = 150 units · 1.7 mg = 255 units.

Question 2

What is the concentration of 2mg of Semaglutide in 3ml?

Accepted Answer

2mg ÷ 3ml = 0.67 mg/ml.

Question 3

Which syringe do these unit marks refer to?

Accepted Answer

A standard U-100 insulin syringe, where 100 units = 1 ml. On U-50 or U-30 syringes the same volume reads as half or 30% of the U-100 marks. These are mathematical conversions for organizational purposes only — not medical advice.

Dose	Draw volume	U-100 units
250 mcg	0.375 ml	37.5 U
500 mcg	0.75 ml	75 U
1 mg	1.5 ml	150 U
1.7 mg	2.55 ml	255 U
