Both target weight loss. Wegovy is semaglutide up to 2.4 mg; Mounjaro is tirzepatide up to 15 mg with dual hormone action and higher average loss in trials.
What matters here
Mounjaro showed greater average weight loss (~20% vs ~15%) but at higher cost. Either is excellent; choice comes down to availability, price and how your body responds — some people simply do better on one.
When to check with your doctor
This is general information, not a prescription. Your dose, your other medicines and your medical history all change the picture — message your ZIVOLABS doctor before making any change to how you take your medication.
What the medication is doing inside your body
Three things happen at once on {b}. First, your stomach empties more slowly, so a small meal keeps you full for hours. Second, appetite signalling in the brain is dialled down, so you think about food less. Third, blood-sugar control improves because insulin is released more efficiently after meals. Together these put you in a gentle, sustainable calorie deficit — the reason people lose roughly 10–20% of their body weight over a year when the medicine is paired with enough protein and some strength training.
Your likely month-by-month journey
-
Month 1 is about tolerance, not the scale — you titrate up slowly so your gut adapts and side effects stay mild.
-
Month 2 is when most people notice clothes fitting looser and portions feeling smaller without effort.
-
Month 3 is the first real checkpoint: if you've lost under 3% of your weight, your doctor reviews the dose or molecule.
-
Months 4–6 deliver the bulk of the visible change, especially around the waist as visceral fat responds first.
-
After 6 months, the focus moves from losing to maintaining — a lower steady dose plus the habits you've built.
Side effects and how to manage them
-
Nausea is the most common, mostly in week one and after each dose increase. Smaller portions, less oily food, ginger or jeera water, and staying upright after eating all help.
-
Constipation responds to three litres of water a day, daily isabgol (psyllium husk), fruit and sprouts, and a short walk after meals.
-
Fatigue usually means you're eating too little — check your protein, iron and B12, and don't cut calories too hard.
-
Reflux eases with lighter, earlier dinners and not lying down after eating; a short course of antacids or a PPI helps if needed.
-
Most side effects are temporary and fade as your body adjusts. Anything severe or persistent — especially intense upper-abdominal pain — should go straight to your doctor.
Is it right for you?
The honest answer needs a doctor, but the broad rules are simple. You're likely a candidate if your BMI is 30+, or 27+ with a condition like diabetes, PCOS or fatty liver, and lifestyle changes alone haven't been enough. You're not a candidate if you're pregnant, breastfeeding, or planning pregnancy soon, or if you have a personal/family history of medullary thyroid cancer or MEN-2. Pancreatitis history and eating-disorder history need careful, individual judgement. A good prescriber assesses all of this before writing anything.
Budgeting for treatment
Plan for roughly ₹16,000–₹26,000 a month, plus consults and occasional lab tests. Prices shift, so confirm current rates with a licensed pharmacy rather than trusting a one-off quote. You can keep costs sensible by using the lowest effective dose, choosing the right molecule for your goal, buying a full month at a time, and tapping any medical-reimbursement allowance from your employer. Avoid the false economy of grey-market pens — counterfeit medication is the most expensive mistake you can make with your health.
How to avoid fake or unsafe medication
If a deal looks too good to be true, it is. Real GLP-1 medicines are expensive because they're complex biologics with a cold chain; suspiciously cheap offers across India are almost always counterfeit. Insist on a licensed pharmacy, a real prescription, an intact hologram and batch number, and proper refrigerated delivery. Never buy 'research peptides' or compounded versions — they aren't approved in India and aren't quality-controlled. Doctor supervision matters here too: the right dose, titrated slowly, is what keeps the medicine both safe and effective.
Frequently asked questions
Do I need to follow a strict diet?
No strict diet, but protein matters: aim for 1.2–1.6 g per kg of body weight a day to protect muscle, and keep fried food and refined carbs modest to avoid nausea.
Is it safe to take long-term?
The evidence to date is reassuring across multi-year trials, including cardiovascular benefit. It's intended for long-term use under medical supervision.
Can I take it if I'm not diabetic?
Yes — GLP-1 medicines are approved for weight management in people without diabetes who meet the BMI criteria, and are used that way safely worldwide.
How much weight can I realistically lose?
Roughly 10–15% of body weight with semaglutide and up to ~20% with tirzepatide over about a year, when paired with adequate protein and some strength training.
How ZIVOLABS supports you through it
ZIVOLABS is built as a doctor-supervised GLP-1 program for India, not just a pharmacy. You start with a proper medical assessment online; a verified doctor reviews your history, confirms whether treatment is appropriate, and writes a genuine prescription if so. Your medication is dispensed by a CDSCO-licensed pharmacy and delivered cold-chain to your door, and you can message your care team whenever side effects or questions come up. Dose changes, plateaus and the eventual step-down to maintenance are all guided — because the medicine works best with a plan and a clinician around it.
Key takeaways
-
Wegovy (semaglutide) reduces appetite and slows digestion, so you eat less without constant hunger.
-
Protein (1.2–1.6 g/kg/day) plus two to three strength sessions a week protect muscle while you lose fat.
-
Side effects are mostly early and manageable; start low, go slow, and report anything severe.
-
Buy only genuine, doctor-prescribed medication from a licensed pharmacy — counterfeits are a real risk in India.
-
It works best as a supervised plan, with a maintenance dose to hold the result rather than stopping abruptly.
Not sure if it's right for you?
If you're weighing up GLP-1 therapy, the safest first step is a proper medical assessment — not a grey-market pen from a stranger. ZIVOLABS doctors will tell you honestly whether you're a candidate. The assessment is free.
