Question 1

How many units is a 1 mg dose of Retatrutide (10mg vial, 1ml diluent)?

Accepted Answer

10 units on a standard U-100 insulin syringe (0.1 ml). Mixing a 10mg vial of Retatrutide with 1ml of bacteriostatic water gives a concentration of 10 mg/ml. On a U-100 insulin syringe that means: 1 mg = 10 units · 2 mg = 20 units · 4 mg = 40 units · 6 mg = 60 units · 8 mg = 80 units.

Question 2

What is the concentration of 10mg of Retatrutide in 1ml?

Accepted Answer

10mg ÷ 1ml = 10 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
1 mg	0.1 ml	10 U
2 mg	0.2 ml	20 U
4 mg	0.4 ml	40 U
6 mg	0.6 ml	60 U
8 mg	0.8 ml	80 U
