Research Tool
Retatrutide is supplied lyophilized across a wide range of vial masses, which makes recording the concentration when the stock solution is prepared particularly worthwhile. Enter the Retatrutide mass in the vial and the diluent volume to get the stock-solution concentration.

Concentration (mg/mL) = peptide mass (mg) ÷ diluent volume (mL). For in-vitro laboratory research use only.
The three common vial masses — 15 mg, 30 mg and 40 mg — produce concentrations that differ by nearly 3× at the same diluent volume.
