Reconstitution Calculator

Enter your vial size, bacteriostatic water, and target dose to get the exact syringe units to draw. For research use only — not medical advice.

This tool performs arithmetic only. It does not set your dose or confirm suitability. For qualified research use only.

Syringe size

All standard insulin syringes use the same U-100 scale — your unit count is identical across all three sizes.

⚠ Check your inputs — all values must be greater than zero.

Add bacteriostatic water slowly down the vial wall — never directly onto the powder. Swirl gently, do not shake. Keep refrigerated (2–8°C) and use within 28 days. Bacteriostatic water is available as an add-on on any retail product page.

How it works

The math behind the numbers

Your peptide dissolves evenly through the water you add, so concentration is simply the peptide mass divided by the solvent volume. Insulin syringes are marked in units, where 100 units = 1 mL (U-100 scale).

Concentration
mg in vial
÷ mL added
= mg / mL
