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

The listed 15 mg, 20 mg, 30 mg and 40 mg vials give 5, 6.67, 10 and 13.33 mg/mL respectively in the same 3 mL example volume.
Default values are arithmetic examples, not preparation recommendations. For in-vitro lab work.
Each value is the vial mass divided by the diluent volume, in mg/mL. These are arithmetic examples, not preparation recommendations.
