Tirzepatide
Mounjaro Tracker
Mounjaro is Eli Lilly's tirzepatide approved for type 2 diabetes, dosed once weekly and titrated from 2.5 mg up toward 15 mg as tolerated. It's the same dual GIP/GLP-1 molecule as Zepbound but carries the diabetes indication, so many people are tracking glucose management alongside the weight loss that tends to follow. Myo gives Mounjaro its own weekly timeline tied to your current dose.
Because Mounjaro is diabetes-labeled, the priority is often steady blood-sugar control, and the titration is paced to balance efficacy against gut side effects. With tirzepatide's ~5-day half-life, levels settle within weeks of each step-up, and Myo's medication-level view shows where you are in the cycle when you log how a dose is hitting you.
Even when the goal is glucose rather than the scale, the appetite drop that comes with Mounjaro can quietly erode muscle. Myo is built muscle-first, so it pairs your Mounjaro log with protein intake, resistance training, and a fat-vs-muscle body-composition trend - keeping strength in the picture, not just A1C.

Mounjaro tracking FAQ
Is Mounjaro tracked the same as Zepbound in Myo?
They're the same tirzepatide molecule with the same dose ladder, so Myo keeps one continuous timeline. The difference is the label - Mounjaro for type 2 diabetes, Zepbound for weight management - and you log which product you're prescribed for accurate records.
I'm on Mounjaro for diabetes, not weight loss - is Myo still useful?
Yes. Myo tracks your weekly dose, injection sites, and side effects regardless of why you're prescribed it, and its muscle-first metrics matter for anyone whose appetite is suppressed. Glucose management and protecting lean mass aren't mutually exclusive.
How does Myo help with Mounjaro side-effect patterns?
By timestamping each dose and letting you log symptoms against the ~5-day curve, Myo helps you see whether nausea or fatigue clusters on particular days of your week. That pattern is useful context to bring to your prescriber - it doesn't replace their advice.
Can I track muscle loss on Mounjaro?
Myo trends the inputs that predict it - protein intake, training frequency, and the body-composition figures you record - so a downward muscle trend becomes visible rather than hidden behind a falling scale weight. Confirm any concerns with your doctor.
