Free Mounjaro Tracker

Mounjaro weeks, counted properly.

Mounjaro is tirzepatide on a once-weekly schedule, often alongside glucose monitoring and regular lab work. Peptide Plug keeps the injection log, the lab values and the weight entries on one timeline, so a review appointment does not start with reconstructing three months from memory.

Labeled titration steps

The manufacturer's labeled steps, offered in the tracker as presets. Increases are described in 2.5 mg increments after at least 4 weeks at the current step.

Step	Typical duration	Notes
2.5 mg weekly	4 weeks	Starting step.
5 mg weekly	4 weeks or longer	First maintenance-capable step.
7.5 mg weekly	4 weeks or longer	Intermediate step.
10 mg weekly	4 weeks or longer	Maintenance-capable step.
12.5 mg weekly	4 weeks or longer	Intermediate step.
15 mg weekly	ongoing	Highest labeled maintenance step.

What goes on the timeline

Mounjaro is usually not the only thing being tracked, so the tracker holds the rest too.

Weekly injectionsDose, date, step and site — the spine of the record.
Lab resultsA1c, fasting glucose and any other marker you enter, plotted against your dose history rather than in a separate file.
Weight entriesOptional, on the same axis, so a plateau or a change lines up visibly with a dose step.
Notes per entryFree text against any injection, for the details that never fit a field.

Why the lab overlay matters

The reason people ask for this specifically.

Appointments are retrospective. A prescriber reviewing your progress is asking what happened over the last three months. A log that shows doses and labs on one axis answers that in a glance; two apps and a photo roll do not.
Dose changes and lab changes are weeks apart. A step change taken in March shows up in an A1c drawn in June. Keeping both on one timeline is what makes that relationship visible at all. Peptide Plug plots them together; it does not interpret them.
Nothing here is an interpretation. The tracker displays what you entered. It does not flag a value as good or bad, does not diagnose, and does not suggest a change. See How the Estimate Works for what the app does and does not model.

Tracking tool only — not medical advice. Peptide Plug records what you enter. It does not recommend a dose, decide when you should move between steps, or evaluate whether a medication is right for you. The steps shown are the manufacturer's labeled titration schedule, included so the tracker can offer them as presets — your prescriber sets your actual schedule.

Frequently Asked Questions

Is Peptide Plug affiliated with Mounjaro or its manufacturer?

No. Peptide Plug is an independent tracking tool with no affiliation to any manufacturer. Mounjaro is a registered trademark of its manufacturer, used here only to describe compatibility. We do not sell or supply medication.

Can I record A1c and glucose readings?

Yes. Lab entries are a first-class part of the tracker and plot on the same timeline as your injections. The app displays your values; it does not evaluate them or tell you what they mean.

What if my injection day changes?

Log the injection on the day it happened. The projector works forward from your most recent real entry rather than from a fixed weekday, so a shifted day recalculates the schedule instead of breaking it.

Does it handle a switch between tirzepatide products?

Yes. More than one compound can sit on the same timeline, so a switch is a continuation of your record rather than a new one. Your earlier history remains readable.

Can I export my history for an appointment?

Yes. Pro accounts export the full history as JSON or CSV. Many people bring the export rather than trying to summarise several months verbally.

Does the tracker remind me?

Pro accounts can enable reorder and expiry alerts. The free tier includes one active cycle and the full calculator set without alerts.

Is there a cost?

The tools on this page are free with no account. The tracker has a free tier for one active cycle, and Pro at $4.99/month or $49.99/year for unlimited cycles, alerts, custom catalog entries and full export.

Where does the dose-step information come from?

The steps shown are the manufacturer's published labeled titration schedule, included so the tracker can offer them as presets. They are not a recommendation, and your prescriber's schedule takes precedence over any preset.
