What this tool calculates

From the milligrams stated on your vial and the millilitres of water you add, the calculator works out the concentration (mg/ml) and converts the dose you enter into a volume and into units on a U-100 syringe, where 1 ml equals 100 units. Some compounds show an educational reference figure you can change; the final value is yours to set. It can also build a weekly calendar and email it as a PDF.
