Weight Loss Medicines: A Practical Guide for People Already on Treatment

The most widely discussed prescription weight loss injections currently available belong to a class of medicines called GLP-1 receptor agonists. Wegovy contains semaglutide, which acts on GLP-1 receptors involved in appetite regulation. Mounjaro contains tirzepatide, a dual GIP and GLP-1 receptor agonist — meaning it acts on two separate appetite-related pathways. Both are prescription-only medicines, taken as a once-weekly injection, and both are started at a low dose that is adjusted over time by the prescriber.

These medicines are not the same as older diet pills or stimulant-based products, and they are not insulin. They work primarily by increasing the sense of fullness, reducing appetite — sometimes described as lowering food noise — and, in many people, slowing the rate at which the stomach empties. The degree to which any individual experiences these effects varies, and your prescriber is the right person to discuss how treatment is working for you.

What about other approaches, such as herbal or traditional remedies?

Searches for terms like Chinese medicine weight loss reflect genuine curiosity about traditional and herbal approaches. It is worth knowing that these are entirely separate from the prescription GLP-1 medicines described above, are regulated differently, and have a different evidence base. If you are curious about combining any supplement or herbal remedy with a prescribed medicine, always discuss this with your prescriber or doctor first — interactions and suitability are highly individual.

For a broader look at how Mounjaro works as a medicine, the Mounjaro guide on GLP Trackr covers the key facts in plain language. If you are also incorporating exercise and training into your weight loss journey, there is practical guidance on how movement fits alongside GLP-1 treatment.

Staying consistent with a weekly injection schedule is one of the most practical challenges people face once they are on treatment. Missing a dose or losing track of where you are in your titration schedule is easier than it sounds — especially across a long programme.

GLP Trackr is a companion app built specifically for people already on Mounjaro or Wegovy. The most directly relevant feature here is dose and injection logging: every time you take your weekly shot, you can record the date, dose strength, and injection site. The app tracks your site rotation history and suggests your next site automatically, so you never have to remember whether you used your left abdomen or right thigh last week.

Beyond dose logging, the app's progress and insights tools let you track weight, mood, energy, sleep, and side effects in one place — turning scattered notes into a clear picture of how your body is responding over time. That record is genuinely useful to bring to your next prescriber appointment. You can also explore whether a concern such as cognitive changes sometimes reported on Mounjaro shows up in your own logged data, rather than relying on memory alone.

If you have come across references to sourcing medicines through unofficial channels — for example, buying Mounjaro through retailers like Amazon — it is important to know that GLP Trackr does not sell, supply, or source any medication. The app supports people who are already prescribed; obtaining your medicine should always go through your prescriber and a registered pharmacy.

Always follow the guidance of your prescriber or doctor — they know your full history and are the right person to make any decisions about your dose or treatment plan. GLP Trackr helps you record what is happening so those conversations are better informed, not replace them.
