Dose calculator
Enter what is in the vial, how much water was added and the dose your healthcare professional set. You get the exact number of units to draw, and a picture of where that is on the syringe.

How it works
The vial's peptide is spread evenly through the water you add, so every millilitre holds the same amount. Divide your dose by that amount to get the volume, then multiply by 100 because insulin syringes have 100 units in each millilitre.
The syringe size doesn't change the answer, only whether it fits. Smaller syringes have finer lines, which makes small draws easier to read.
This tool does arithmetic on numbers you enter. It does not suggest or check doses. Your dose and how to mix it come from your healthcare professional.
