Quick answer

To track Zepbound well you need four things: every dose logged with its injection site, a reminder tuned to your weekly schedule, your estimated medication level between doses, and side effects tied to each dose step. GLPMate does all four — free to start, on iOS and Android.

FAQ

Zepbound tracking questions

How do I track Zepbound with vials instead of pens?

GLPMate’s dose calculator converts mg to syringe units (U-100) for vial users, and every log stores the exact mg — pen or syringe, brand or compounded.

What if I miss a Zepbound dose?

Within 96 hours: take it. Past that: skip and resume on schedule. GLPMate reminds you before the window closes.

Why do I feel hungrier the day before my shot?

That’s your trough — the lowest point of your level curve. Tirzepatide’s ~5-day half-life makes pre-dose dips noticeable for some people. Seeing it on the chart helps you plan those days instead of being surprised by them.

Can I see my level between doses?

Anytime. GLPMate estimates your current level from your actual dose history — updated the moment you log a shot.

Does GLPMate track weight alongside Zepbound doses?

Weight, BMI, measurements and progress photos all live next to your dose timeline, so trends line up with dose changes at a glance.

Is GLPMate affiliated with Eli Lilly?

No. GLPMate is an independent tracking app. Zepbound® is a trademark of Eli Lilly; we just help you track your prescribed treatment.
