PT-141 dosing chart: how to read it
Choose a column that matches your vial and the amount of water you added, such as 10 mg and 2 mL. Then go down to your dose. That cell tells you the unit count to draw with a U-100 insulin syringe. If the water you add isn't listed, the calculator figures it out for any amount.
