Same ingredient, different licences: understanding semaglutide
Semaglutide is a GLP-1 receptor agonist — a class of prescription-only, once-weekly injectable medicines that act on appetite-regulating pathways in the body. Many people experience a greater sense of fullness and a reduction in appetite (sometimes called reduced "food noise") while taking them, though individual responses vary.
Ozempic
Ozempic (semaglutide) is licensed primarily for the management of type 2 diabetes. It is not, in itself, a weight-management medicine, though weight changes are commonly reported. Ozempic is prescription-only and available in specific dose strengths; your prescriber will have chosen it for reasons specific to your health.
Wegovy
Wegovy is also semaglutide, but it is specifically licensed for chronic weight management in adults who meet defined criteria. It is prescribed at higher dose strengths than Ozempic. As with all prescription medicines, suitability is decided by a prescriber based on your individual circumstances. You can find general information about Wegovy and how it is used on the GLP Trackr hub.
Where Mounjaro fits in
A third medicine — Mounjaro (tirzepatide) — is also commonly discussed alongside these two. Unlike semaglutide, tirzepatide acts on both GLP-1 and GIP receptors. It is a separate prescription-only medicine licensed for weight management and type 2 diabetes. For a neutral, factual look at how semaglutide and tirzepatide compare, see our page on Mounjaro versus Ozempic, or explore the broader Mounjaro information hub. There is also a focused comparison of Ozempic and Mounjaro side by side if that is relevant to your journey.
Which of these medicines is appropriate for any individual is a clinical decision. If you have questions about why you were prescribed one over another, or whether a switch might be relevant, that conversation belongs with your prescriber or doctor — they have the full picture of your health history.

Tracking your semaglutide journey with GLP Trackr
Whichever form of semaglutide you have been prescribed, staying consistent week to week makes a real difference — and that is where GLP Trackr is designed to help.
The app's dose and injection logging lets you record every weekly shot: the date, the dose strength, and where on your body you injected. Because semaglutide is taken once a week, it can be easy to lose track of exactly when your last dose was or which injection site you used. GLP Trackr logs each one and keeps a rotation history so you always know where to inject next.
The side-effect tracker is equally useful. Gastrointestinal symptoms — such as nausea, indigestion, or changes in appetite — are commonly reported on semaglutide, particularly after a dose adjustment. Logging how you feel after each injection helps you spot patterns over time, and the app can generate a summary you can bring to your next prescriber appointment rather than trying to recall weeks of experience from memory.
GLP Trackr supports users on Wegovy, Ozempic, and Mounjaro, so wherever you are in your journey, the tracking tools are built around the realities of GLP-1 life.
If any side effects feel severe, persistent, or worrying at any point, contact your healthcare professional promptly — GLP Trackr is a tracking companion, not a substitute for clinical advice.

The Most Advanced GLP-1 Brain Ever Built.
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.
Knows Your Cycle
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.
