Understanding the Options: Mounjaro and Wegovy
The two injectable medicines most commonly associated with weight management are Mounjaro (tirzepatide) and Wegovy (semaglutide). Both are prescription-only and administered once weekly using pre-filled pens. Here is a factual, neutral overview of each.
Mounjaro (tirzepatide)
Tirzepatide is a dual GIP and GLP-1 receptor agonist. It acts on two appetite-regulating pathways — GIP and GLP-1 — which are involved in feelings of fullness and appetite regulation. It is typically started at a low dose and adjusted over time by a prescriber. Like all medicines in this class, it carries a black triangle (▼) designation, meaning it is subject to additional monitoring; any side effects should be reported to your healthcare professional and your national reporting scheme (such as the UK's Yellow Card scheme).
Wegovy (semaglutide)
Semaglutide is a GLP-1 receptor agonist, acting on one of the same appetite-regulating pathways. It is also taken once weekly via a pre-filled pen, starting at a low dose with prescriber-led adjustment over time. It similarly carries the ▼ designation and the same reporting guidance applies.
What about menopause and other individual factors?
Some people searching for which weight loss injection is best for menopause are looking for reassurance that these medicines work during hormonal transitions. While it is common for people at various life stages to be prescribed these medicines, whether a particular medicine is appropriate given your hormonal health, age, other conditions, or medications is entirely a matter for your prescriber. No article can determine that for you.

How GLP Trackr Supports Whichever Injection You Are Prescribed
Once your prescriber has determined which injectable medicine is right for you, staying consistent with your weekly injection schedule becomes one of the most important parts of the journey. GLP Trackr is built specifically for people already on Mounjaro or Wegovy, and its injection-site tracking and rotation feature is where it really earns its place.
Each time you inject, you can log the site — abdomen, thigh, or upper arm — and the app keeps a rotation history so it can suggest where to inject next. Rotating sites is generally recommended to keep skin in good condition, and having an automatic record means you never have to try to remember where you injected last week. You can also log the dose strength and date of each shot, so your injection history is always in one place — useful to review before a prescriber appointment.
Alongside site tracking, the dose reminder feature means your weekly schedule stays on track even when life gets busy. Never wondering "did I already take this week's dose?" is a small thing that makes a real difference over months of treatment.
Always follow the guidance of your prescriber or doctor — they know your full medical history and are the right person to advise on which medicine is appropriate for you and how to use it. If you experience any side effects that are severe, persistent, or concern you, contact your healthcare professional promptly.
GLP Trackr supports both Mounjaro and Wegovy users from day one. Track your injection sites, log every dose, and let the app suggest your next rotation — available free on the App Store and Google Play, with a 7-day trial to get started.

Frequently asked questions.
There is no universally "best" weight loss injection. Both Mounjaro and Wegovy are prescription-only medicines, and which is appropriate for you depends on your individual health history. Only your prescriber or doctor can make that determination — it is not something any app or article can decide.
Mounjaro (tirzepatide) is a dual GIP and GLP-1 receptor agonist, while Wegovy (semaglutide) is a GLP-1 receptor agonist. Both are once-weekly injectable prescription medicines. Your prescriber will consider your full health picture when deciding which, if either, is suitable for you.
Whether a weight loss injection is appropriate during menopause depends on your individual circumstances, other health conditions, and any other medicines you take. This is a question to discuss directly with your prescriber or doctor, who can assess your full situation and advise accordingly.
GLP Trackr helps you log each injection — recording the date, dose strength, and injection site — and tracks your rotation history to suggest where to inject next. It also sends dose reminders so you never miss a weekly shot. The app supports both Mounjaro and Wegovy users.
Any decision to switch between injectable medicines is a clinical one that must be made with your prescriber or doctor. Never change, start, or stop a prescription medicine without their guidance. Your prescriber will consider your health history, response to treatment, and any other relevant factors.
