Research calculator

Peptide reconstitution calculator.

Convert vial mass, diluent volume, and research target amount into concentration, U-100 syringe units, draw volume, fit warnings, and estimated vial yield.

Build the vial

Convert a target amount into syringe units.

Compound

Common SubQ research: Small target amounts usually fit a U-100 syringe cleanly.

Syringe size

U-100 units are tied to insulin-style syringe markings. If the result exceeds the selected size, AtlasED shows the number of syringe fills instead of pretending it fits.

Dose fits selected syringe

Your inputs create 0.1 mL, which fits inside the selected 1 mL U-100 syringe.

Smart recommendation

This fits inside one 1 mL / 100 unit U-100 syringe and should be easier to read than very tiny or maxed-out draws.
