What You Should Know About Weight Loss Injections
Mounjaro and Wegovy are both once-weekly injectable medicines prescribed for weight management. Mounjaro contains tirzepatide, a dual GIP and GLP-1 receptor agonist, while Wegovy contains semaglutide, a GLP-1 receptor agonist. Both work on appetite-regulating pathways and are commonly described as reducing hunger and increasing feelings of fullness — though individual responses vary.
They are prescription-only for a reason
Because these are prescription-only medicines, suitability is determined entirely by a prescriber who knows your medical history. Whether you access them through a private clinic or another route available in your country, the prescription and dispensing must go through qualified, registered healthcare professionals. GLP Trackr does not sell, supply, or help you obtain any medication — if you have questions about access or cost, your prescriber or doctor and a registered pharmacy in your country are the right starting points.
Injection sites and rotation matter
Most people inject into one of three areas: the abdomen, the upper thigh, or the upper arm. Rotating between sites — rather than using the same spot each time — is generally recommended to allow the skin and underlying tissue to recover. Your prescriber or the patient information leaflet that came with your pen will give you guidance specific to your medicine. For a broader look at how these injections work in practice, the weight loss injections overview covers the key points, and you can also explore guidance on weight loss jabs for related information.
Commonly reported experiences
Gastrointestinal effects — nausea, constipation, indigestion — are among the most commonly reported side effects, particularly in the early weeks or after a dose adjustment. These are worth logging: patterns in timing and severity can be genuinely useful to share with your prescriber. For a detailed look at the injection process itself, see what to expect from your weight loss injection.

How GLP Trackr Helps You Get the Most From Every Injection
Staying consistent with a weekly injection schedule is simpler when you have a clear record of every dose. GLP Trackr is built specifically for people already on Mounjaro or Wegovy, and the feature that matters most for injection routines is injection-site tracking and rotation: log each site you use and the app keeps a history, then suggests your next site automatically so you are never guessing.
Alongside site rotation, dose logging means every injection is recorded with its date, time, and strength — useful both for your own peace of mind and for producing a clear summary to bring to your next prescriber appointment. The app also sends gentle dose reminders so a weekly shot does not slip your mind during a busy week.
If you experience side effects after an injection, the side-effect tracker lets you note what you felt and when, building a picture over time that is much easier to discuss with your healthcare professional than trying to recall from memory.
GLP Trackr helps you record this information so you can discuss it with your prescriber — it is not a substitute for their advice. If you experience anything severe, persistent, or worrying after an injection, contact your healthcare professional promptly. Any questions about your dose or injection technique should always go to your prescriber or doctor, not an app.

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.
No. GLP Trackr is a tracking and journaling app — it does not sell, supply, or source any medication. Mounjaro and Wegovy are prescription-only medicines available only through a prescriber and a registered pharmacy in your country.
Common injection sites are the abdomen, upper thigh, and upper arm. Your prescriber or the patient information leaflet that came with your pen will confirm which sites are suitable for your specific medicine and circumstances.
Rotating sites allows skin and tissue to recover between injections and reduces the risk of localised reactions. Rather than returning to the same spot each week, moving between areas — abdomen, thigh, arm — is generally recommended. Your prescriber can advise on the best rotation pattern for you.
GLP Trackr logs each injection — site, dose strength, date and time — and suggests your next rotation site automatically. Dose reminders help you stay on your weekly schedule, and a log of your injections can be shared with your prescriber at appointments.
Mild redness or tenderness at an injection site is commonly reported. If a reaction is severe, spreads, or does not resolve, contact your healthcare professional promptly. Do not adjust your injection technique or dose without guidance from your prescriber or doctor.
