Calculator
Peptide reconstitution calculator
Work out your concentration, then convert any target dose into insulin-syringe units — with a to-scale syringe showing exactly where to draw.

The math
How the numbers are worked out
The calculator uses the standard U-100 insulin-syringe relationship, where 1 unit = 0.01 mL:
- Concentration (mg/mL) = peptide in vial ÷ water added.
- Per unit = concentration × 10 (the mcg in each 0.01 mL unit).
- Volume per dose (mL) = target dose ÷ concentration.
- Draw (units) = volume × 100.
- Doses per vial = vial amount ÷ dose (rounded down).
It also highlights the nearest achievable syringe mark, the percentage off target, and warns when a draw is too small to measure or too big for the barrel — then recommends a better syringe.
