Calculator tools

Five more calculators for the arithmetic around a vial. Each one works from the numbers on your label and prescription and shows the formula it uses.

• Bacteriostatic water calculatorHow much water to add for a chosen draw size
• Vial supply calculatorDoses per vial and how long a vial lasts
• Unit convertermcg, mg and g; mL and syringe units; IU and mg
• Syringe units chartUnits to mL for U-100 syringes, and U-40 vs U-100
• Blend calculatorAmount of each component in a multi-peptide vial
• Reconstitution calculatorVial, water and dose to syringe units

What these tools do

They multiply and divide. None of them suggests a dose, a frequency or a product. The inputs are the amount printed on your vial, the water you added and the dose and schedule your prescriber gave you.

Every result should be checked against the vial label and your pharmacy instructions before drawing.
