Personalized Dosing Calculator

Retatrutide Titration Schedule & Efficacy Forecast

Set individual patient parameters, target maintenance dose, and escalation speed to automatically calculate weekly dosing, body weight, and blood sugar trajectory.

Key TRIUMPH Standard

Start at 2 mg once weekly

Starting at 2 mg reduces GI side effect risks by 40% compared to early 4 mg initial dose protocols.

1. Clinical Patient Parameters

Indication for Use

Target Maintenance Dose

12 mg - maximum dose (-28.3% at week 80, TRIUMPH-1); the dose is never raised above 12 mg and is held until week 108. Lower targets (4/8/10 mg) are estimates.

Titration Speed

Cautious speed recommended for elderly patients or significant nausea.
