Retatrutide dose math, solved in the app
How retatrutide reconstitution math works, from vial strength and bacteriostatic water to U-100 syringe units, and the app calculator that saves your vial.
Retatrutide is an investigational once-weekly peptide studied for weight management and is not FDA-approved. This page explains the dose math for a reconstituted vial: concentration in mg/mL is the vial contents divided by the bacteriostatic water added, and the units to draw on a U-100 insulin syringe are the dose in milligrams divided by the concentration, times 100. The calculator itself now lives in the free GLPeak app, which saves your vial, converts each dose your prescriber set into syringe units, logs the dose and tracks side effects. Frequently asked questions cover reconstitution and retatrutide's approval status. Educational only, not medical advice.
