Compound calculators

Reconstitution & Draw Calculator

Vial strength, BAC water volume, and target dose convert into concentration, draw volume, and U-100 barrel units.

Inputs

Compound

The same mass-to-volume arithmetic applies to each selection. Enter your own values; no recommended doses are supplied.

Vial size (mg)

BAC water added (mL)

Target dose

Dose unit

Syringe size (U-100 scale)

All standard insulin syringes are U-100: 100 units = 1 mL, regardless of barrel size.

This tool performs arithmetic only. It does not verify that a dose is safe, appropriate, or legal for any individual or compound. U-100 syringe units measure volume; they are not compound activity units (IU). This calculator is for mass-based vial contents only, not IU-labelled products, blends, tablets, or oil-based formulations.
