These web-only calculators and converters are separate from the Amidra iOS app, which does not calculate dosing or preparation. Enter your own values here — nothing is pre-filled, and nothing is ever suggested to you.
Reconstitution calculator
Vial amount, diluent volume, target dose in — concentration, draw volume and syringe units out, with the formula shown at every step.
Open the calculator →Peptide reconstitution chart
A printable chart of vial strength × bacteriostatic water → concentration, plus micrograms per U-100 unit. Save it as a PDF for the fridge.
Open the chart →Tirzepatide units ↔ mg converter
Enter your vial's concentration and convert between mg and U-100 units, both directions, with a worked example table for common concentrations.
Open the converter →Semaglutide units ↔ mg converter
Convert compounded semaglutide between mg and U-100 units from your vial's concentration, both directions, with a worked example table.
Open the converter →mg to units calculator
The general-purpose version: turn any peptide's mg dose into syringe units (and back) once you know the concentration on your label.
Open the calculator →These web tools never recommend a dose, compound, or schedule. They only convert the values you enter and are not features of the Amidra iOS app — always verify with a qualified healthcare professional.
