A focused set of tools for concentration, vial-volume, syringe-unit, dilution, and reference calculations. Each result is based only on the values you enter.
Find concentration from vial amount and BAC water volume.
Open toolCompare common vial sizes and liquid volumes at a glance.
Open toolCompare concentration before and after adding liquid.
Open toolConvert mL to U-100 syringe markings and back again.
Open toolConvert a known concentration and mass into mL and units.
Open toolEstimate mathematical remaining amount from a half-life.
Open toolConvert a prescribed vial dose from mg to mL and U-100 units.
Open toolCalculate fixed component ratios in a clearly labeled blend vial.
Open toolUse the reconstitution calculator when you know the vial amount and liquid volume. Use the U-100 or mcg-to-units tools only after you know the concentration. The main Peptide Calculator is the best starting point when you want to check a specific target amount from a prepared solution.
