Pick water volume
More water creates a lower concentration, which makes small draws easier to measure. Less water creates a stronger solution and smaller draw volumes.

Reconstitution and draw calculator
Estimate concentration and draw volume from vial mass, bacteriostatic water volume, and target research amount. This is an arithmetic tool only, not dosing advice.

How it works
Reconstitution makes a powder measurable.
Research peptides usually arrive lyophilized, which means freeze-dried powder. Reconstitution is the step where bacteriostatic water is added so the vial becomes a liquid solution that can be measured consistently.
Read the full handling guideCalculate concentration
Divide peptide mass by water volume. A 10mg vial with 2ml water becomes 5mg/ml.
Convert to units
Divide the target amount by the concentration. On a U-100 syringe, 1ml equals 100 units, so 0.05ml equals 5 units.
What it calculates
The calculator converts vial mass and reconstitution volume into mg/ml and mcg per insulin-syringe unit, then estimates the draw needed for a target research amount.
Assumptions
It assumes a 1ml U-100 insulin syringe where 100 units equals 1ml. Change the water volume if your research protocol uses a different concentration.
