Peptide Reconstitution Calculator

It converts a dry peptide vial into an exact, drawable dose. You enter the peptide amount in the vial, the volume of bacteriostatic water you add, and your target dose. It returns the concentration (mg/mL), the volume to draw, the exact units on a U-100 insulin syringe, how many doses the vial yields, and the cost per dose.

There is no single 'correct' amount — more water makes the solution easier to measure but increases injection volume. A common approach is to choose a water amount that makes your typical dose land on an easy-to-read syringe line. Enter different water amounts in the calculator and watch the 'units to draw' update until it's a round, easy number.

On a standard U-100 insulin syringe, the small tick marks are units (100 units = 1 mL). The calculator's 'draw to this line' number is the unit mark to pull the plunger to. The on-screen syringe shows exactly where that falls.

Doses per vial = total peptide in the vial ÷ your dose per injection. The calculator computes this automatically and also estimates cost per dose if you enter the vial price.
