Why Wegovy and Mounjaro Doses Cannot Be Directly Compared
Wegovy contains semaglutide, a GLP-1 receptor agonist, while Mounjaro contains tirzepatide, a dual GIP and GLP-1 receptor agonist. Because they act on different receptors and are measured in different therapeutic ranges, the numbers on the pen are not interchangeable.
How each titration schedule is typically structured
Wegovy is typically started at 0.25mg once weekly and titrated through 0.5mg, 1mg, and 1.7mg before reaching the 2.4mg maintenance dose — always under prescriber direction. Mounjaro commonly begins at 2.5mg once weekly, with the prescriber adjusting upward through 5mg, 7.5mg, 10mg, 12.5mg, and up to 15mg over time. The dose numbers look very different because the two medicines are measured on entirely separate scales.
Why people look for equivalents
Many people switching between the two medicines — or curious about how their current dose compares — search for a direct conversion. It is a reasonable question, but there is no clinically validated conversion table that maps, say, 1mg semaglutide to a specific tirzepatide dose. Factors such as individual response, tolerability, and treatment history all influence what dose is appropriate for any given person.
For specific questions about how Wegovy doses at 0.5mg, 1mg, 1.7mg, or 2.4mg relate to what you have been prescribed, the most useful resource is your own prescriber or doctor. You can read more about what a 1mg Wegovy dose means in context, or explore how Wegovy doses are sometimes compared to 5mg Mounjaro for further background. For a broader look at the 5mg Mounjaro dose stage, the Mounjaro 5mg guide covers what to expect at that point in titration.
If you are thinking about the highest end of the Wegovy schedule, the 2.4mg Wegovy and Mounjaro comparison explores that question in more detail.
Always follow your prescriber or doctor's instructions regarding your dose — they are the only person who can make dose decisions based on your full medical history.

Tracking Your Dose Journey with GLP Trackr
Whether you are on Wegovy or Mounjaro, keeping an accurate record of every dose you take is one of the most practical things you can do to stay on top of your treatment.
GLP Trackr's dose logging feature lets you record each injection — the date, time, and dose strength — so you always have a clear, timestamped history of where you are in your titration schedule. This is particularly useful if you are mid-titration and want to bring a complete record to your next prescriber appointment, or if you have any questions about your schedule and need to show exactly what you have taken and when.
The app also includes dose reminders, so a once-weekly injection is less likely to slip your mind during a busy week. If you do miss a dose, log it in the app and discuss what to do next with your prescriber — dose decisions, including what to do after a missed injection, always belong with your healthcare professional.
GLP Trackr is available free on the App Store and Google Play, with a 7-day trial to get started — download it and start building your dose log today.
If you have questions about how your current dose is working, how you are feeling, or whether a change might be right for you, bring your logged history to your prescriber or doctor. GLP Trackr is a tracking companion — it records your journey and helps you have more informed conversations with your clinical team, but it is not a substitute for their guidance.

GLPIQ tracks where you are in your injection cycle and adjusts everything around it: lighter meals on nausea days, higher protein when appetite returns, and smarter targets as your medication level shifts.
Predicts Before You Feel It
GLPIQ learns your personal side effect patterns over time. After a few cycles, it starts warning you the morning before a rough day — and adjusts your meal plan automatically.
Finds Your Golden Dose
GLPIQ analyses every dose you've been on: weight loss rate, side effects, food noise, mood, protein adherence and tells you which dose gave you the best results. No other app does this.

Frequently asked questions.
There is no direct milligram-for-milligram equivalent between Wegovy (semaglutide) and Mounjaro (tirzepatide). They use different active substances and operate on separate dose scales. Any comparison or switch between the two is a decision for your prescriber or doctor, not a self-managed conversion.
Wegovy is typically titrated through 0.25mg, 0.5mg, 1mg, and 1.7mg before reaching a 2.4mg maintenance dose, always under prescriber direction. The exact schedule for any individual depends on their response and tolerability, as determined by their healthcare professional.
Mounjaro commonly starts at 2.5mg once weekly and is adjusted upward through 5mg, 7.5mg, 10mg, 12.5mg, and up to 15mg, with the prescriber directing each increase. The large difference in numbers compared to Wegovy reflects the fact that the two medicines are on entirely separate dosing scales.
No. Switching between medicines is a clinical decision that must be made by your prescriber or doctor. They will consider your medical history, current response, and tolerability before making any recommendation about changing your treatment.
GLP Trackr lets you log each injection with the date, time, and dose strength, building a clear record of your titration journey. This log can be useful to share with your prescriber at appointments, helping them see exactly where you are in your schedule.
