Work out how much bacteriostatic water to add to a vial, how many units to draw on a U-100 syringe for your dose, and how many doses a vial gives. Works for single peptides and blends.

How to use the calculator

• How much water to add? Enter the mg in the vial and your dose. Tap a water amount in the table to see the draw on the syringe, or choose “I want to draw…” and enter the number of units you want per dose.
• Already mixed: enter the mg in the vial and the water you added. See the dose for each number of units, or enter your dose to get the units to draw.
• Blends: tap “Add another peptide” and enter each ingredient. Choose which one your dose is for; the calculator shows how much of each you get per draw.
• Syringes: U-100 insulin syringes hold 100 units per 1 mL. Pick 1 mL, 0.5 mL or 0.3 mL to match yours.
