Understanding the New Generation of Injectable Weight Loss Medicines
Mounjaro and Wegovy belong to a class of prescription-only, once-weekly injectable medicines that act on appetite-regulating pathways in the body. Wegovy contains semaglutide, a GLP-1 receptor agonist, while Mounjaro contains tirzepatide, which acts on both GLP-1 and GIP receptors. Both are taken by subcutaneous injection and are started at a low dose, with any adjustment made by your prescriber over time — never on your own.
These medicines are not suitable for everyone, and suitability is always a clinical decision. If you are already prescribed one, your prescriber will have weighed the benefits and risks for your specific situation. For a factual side-by-side look at how these two medicines compare, see how Wegovy works as a weight loss medicine or read a broader overview of prescription weight loss drug options.
Why progress looks different for everyone
Many people starting an injectable weight loss medicine expect a steady, predictable loss each week. In reality, progress varies considerably depending on starting weight, diet, activity, sleep, stress, dose stage, and individual biology. Plateaus are common and do not necessarily mean the medicine has stopped working. Understanding this — and having the data to see your own patterns — makes it far easier to stay consistent and have informed conversations with your prescriber.
- Weight loss is often more rapid in the early months and may slow over time.
- Non-scale measures — energy, appetite changes, measurements, mood — are a meaningful part of the picture.
- Consistency with both the medicine and supportive habits (protein intake, hydration, movement) is widely associated with better outcomes, though individual results will vary.

Tracking Your Progress on a New Weight Loss Medicine with GLP Trackr
GLP Trackr is built specifically for people already taking Mounjaro or Wegovy, and its weight and progress tracking features are designed around the realities of GLP-1 life. The weekly transformation view lets you see how your body is changing over time — not just on the scale, but across measurements, energy, mood, and sleep — so you are never relying on a single number to judge how things are going.
The insights and analytics tools go further: a plateau forecast, correlation explorer, and daily brief help you spot what is actually influencing your results from your own logged data. If you notice a stall, you will have real information to bring to your next prescriber appointment rather than a vague sense that things have slowed down.
The daily morning check-in takes around 30 seconds — log your weight, mood, food noise, energy, and sleep in one place — and over weeks this builds into a picture of your journey that no single weigh-in could capture.
GLP Trackr does not provide medical advice and is not a substitute for your prescriber's guidance. Any concerns about your progress, your dose, or how you are feeling should always be discussed with your healthcare professional — they know your full history.

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.

Frequently asked questions.
The most widely prescribed injectable weight loss medicines currently include Mounjaro (tirzepatide) and Wegovy (semaglutide). Both are prescription-only, once-weekly injections. Whether either is suitable for you is a decision for your prescriber or doctor.
Results vary considerably between individuals and are not guaranteed. Progress depends on factors including starting weight, dose stage, diet, activity, and individual biology. Many people see results over months, but progress is rarely linear. Your prescriber is best placed to set realistic expectations.
Plateaus are commonly reported on GLP-1 medicines and do not necessarily mean the medicine has stopped working. Factors such as dose stage, diet, sleep, and activity all play a role. If you are concerned about a plateau, discuss it with your prescriber or doctor rather than adjusting your dose independently.
Logging weight, measurements, energy, mood, and food alongside your dose can reveal patterns that a single weigh-in misses. GLP Trackr is a companion app built for people on Mounjaro or Wegovy that brings all of this into one place, with charts and insights drawn from your own data.
Yes. GLP Trackr supports people already prescribed either Mounjaro (tirzepatide) or Wegovy (semaglutide). You can log your dose, track injection sites, monitor side effects, and follow your weight and wellbeing progress whichever medicine you are on.
