What Is the Slimming Injection and How Is It Accessed?
The medicines most often called the "slimming injection" are Mounjaro (tirzepatide) and Wegovy (semaglutide). Both are prescription-only, once-weekly injectable medicines used alongside diet and lifestyle changes for weight management in adults. Mounjaro works on both GLP-1 and GIP receptors, while Wegovy works on the GLP-1 receptor — both act on appetite-regulating pathways and are commonly associated with a reduced sense of hunger and increased feelings of fullness.
How access works
Because these are prescription-only medicines, access is determined by a qualified prescriber who assesses whether the treatment is appropriate for you individually. Availability and funding arrangements vary depending on where you live and your healthcare system — there is no single universal route. In some countries, funding through a national health scheme may be available in specific circumstances; in others, it is obtained privately through a registered pharmacy. For questions about whether you can get the slimming injection and what is involved, your prescriber or doctor is the right person to speak to.
Is it safe?
Both medicines are prescription-only precisely because suitability depends on an individual's full medical history. They are not appropriate for everyone, and your prescriber will have weighed the potential benefits and risks before prescribing. As with all medicines, side effects are possible — gastrointestinal effects such as nausea, constipation, or indigestion are among the most commonly reported. If you experience anything severe, persistent, or worrying, contact your healthcare professional promptly. You can read more about the evidence and practical experience of these medicines on our page about how the slimming injection works.

Tracking Your Injection Journey with GLP Trackr
Once you have been prescribed a slimming injection and have started your treatment, keeping track of each dose and injection site becomes a regular part of your week. GLP Trackr is built specifically for this.
Injection-site tracking and rotation
The app lets you log each injection — recording the site (abdomen, thigh, or upper arm), the date, and the dose strength. Because rotating injection sites is generally recommended to keep the skin in good condition, GLP Trackr tracks your rotation history and suggests where to inject next, so you never have to remember manually. For more detail on managing your sites day to day, see our page on injection site guidance for slimming injections.
Dose reminders and dose logging
A weekly injection is easy to lose track of — especially during the early weeks of a new routine. The app sends gentle reminders so you never miss a dose, and keeps a clear log of every injection you have recorded, which you can refer back to or bring to your next prescriber appointment.
GLP Trackr is a tracking and journaling tool — it is not a substitute for clinical guidance. Any questions about your dose, your treatment plan, or whether this medicine is right for you should always go to your prescriber or doctor, who knows your full history.

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.
