How do I use this calculator?
Select your compound (e.g., Semaglutide/Ozempic)
Choose your desired dose
Enter the total mg in your vial
Enter the volume of water added
The calculator will show how much to draw in your syringe
Why is water volume important?
The amount of water determines the
concentration of your solution. For example:
5 mg vial with 1 mL water = 0.5 mg per 0.1 mL
5 mg vial with 2 mL water = 0.25mg per 0.1 mL
10 mg vial with 2 mL water = 0.5 mg per 0.1 mL
