How Wegovy and Mounjaro Differ — and Why It Matters
Wegovy (semaglutide) and Mounjaro (tirzepatide) both influence appetite-regulating pathways, but their mechanisms are distinct. Wegovy acts on GLP-1 receptors, which play a role in feelings of fullness and slowing the rate at which the stomach empties. Mounjaro acts on both GLP-1 and GIP receptors — a dual-receptor approach that is different in its pharmacology. For a fuller explanation of how tirzepatide works, see how Mounjaro works.
Are they comparable in effectiveness?
Clinical trial programmes for both medicines have reported meaningful average weight reductions in participants, but the trials were designed differently, used different populations, and cannot be directly compared on headline numbers alone. Neither medicine works the same way for every person — individual response depends on many factors including medical history, lifestyle, and the dose prescribed. Suitability and expected outcomes are something only your prescriber or doctor can assess for you.
What about Ozempic and orlistat?
Ozempic also contains semaglutide, the same active substance as Wegovy, but is licensed for a different indication. If you are curious about the relationship between these medicines, the pages on whether Wegovy and Ozempic are the same and Wegovy versus Ozempic cover this in more detail. Orlistat works through an entirely different mechanism — it reduces the absorption of dietary fat in the gut — and is not in the same drug class as semaglutide or tirzepatide. Comparing orlistat to Mounjaro is therefore not straightforward.
Is one "better" than the other?
No independent body or regulator has concluded that one of these medicines is universally superior to the other. Both are prescription-only for a reason: suitability is individual. If you are already prescribed one of these medicines and are wondering whether a different option might suit you better, that conversation belongs with your prescriber — they can weigh your full medical history in a way that no article can. You may also find it useful to read about how Mounjaro and Ozempic compare as background context.

Tracking the right four numbers — weight, waist, protein and dose — turns a noisy chart into a clear story. That's the loop GLP-1 users keep coming back for.
AI Meal Tracking. Built for GLP 1 Appetites.
Point your camera at any meal and let our AI do the rest. Breakfast, doses, weight, mood all tracked in seconds.
Tracking Whichever Medicine You Are Taking with GLP Trackr
Whichever medicine has been prescribed to you, one of the most useful things you can do is build a consistent picture of how it is working for you personally. GLP Trackr's insights and analytics feature is designed exactly for this — it surfaces patterns from your own logged data, such as how your weight trend, energy levels, and food intake relate to each other over time, and generates a daily brief and week-at-a-glance summary so you can see your progress clearly.
The app also includes side-effect tracking, so if you are experiencing symptoms like nausea, fatigue, or digestive changes, you can log them alongside your dose records. Over time this creates a clear picture you can bring to your prescriber appointments — far more useful than trying to recall how you felt three weeks ago. If you are ever considering whether your current medicine is working for you, that documented record is exactly what your prescriber or doctor needs to make an informed decision with you.
GLP Trackr supports users on both Wegovy and Mounjaro, so whichever you have been prescribed, the app works around your journey. Any decision about switching, adjusting, or continuing your medication should always be made with your prescriber — they know your full history and are best placed to advise you.

The first AI built exclusively for GLP-1 weight loss. Every insight, every meal plan, every prediction trained on one thing only: helping you get the most out of your medication.

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.
Both medicines have shown meaningful weight-loss effects in clinical trials, but the trials were designed differently and cannot be compared directly. Individual response varies. Only your prescriber or doctor can advise which medicine is appropriate for you based on your personal medical history.
Wegovy contains semaglutide, a GLP-1 receptor agonist. Mounjaro contains tirzepatide, which acts on both GLP-1 and GIP receptors. They are different medicines with different mechanisms, both available by prescription only.
Ozempic and Wegovy both contain semaglutide but are licensed for different indications and come in different dose ranges. They are not the same product even though they share an active substance. Your prescriber can explain which is relevant to your situation.
Any decision to switch, stop, or change your prescribed medicine must be made with your prescriber or doctor. They can assess your individual circumstances and advise appropriately. GLP Trackr can help you log your journey and prepare a summary to discuss at your next appointment.
Yes. GLP Trackr supports people already prescribed either Wegovy or Mounjaro, helping them log doses, track side effects, monitor progress, and build insights from their own data — whichever medicine they have been prescribed.
