Reconstituting a peptide vial? Enter your numbers below and get your concentration and the exact units to draw on an insulin syringe — with a visual to match. Built for accuracy, simplified for real life.
Reconstituting a peptide means mixing the powder in your vial with bacteriostatic water so you can draw an accurate dose. Enter your numbers below — or tap a preset — and the calculator does the rest, including showing exactly where to fill your syringe.
Concentration = peptide amount ÷ water volume. Your draw volume = desired dose ÷ concentration. On a U-100 insulin syringe, 1 mL = 100 units, so units to draw = draw volume (mL) × 100. Always double-check against your vial's label.
