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.
How GLP-1 medicines actually work
GLP-1 (glucagon-like peptide-1) is a hormone your gut releases after you eat. It tells your brain you're full, slows how fast your stomach empties, and helps your body release insulin when blood sugar rises. {b} is an engineered, long-lasting version of that hormone: where your natural GLP-1 is broken down in minutes, the medicine keeps working for about a week. The result is that you feel satisfied sooner, stay full longer, and the constant background 'food noise' quietens — so eating less stops feeling like a daily battle of willpower and starts feeling natural.
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.
The side effects nobody warns you about (and the fixes)
-
Early nausea and a feeling of fullness after just a few bites are the medicine working — eat protein first so those bites count.
-
Constipation and a little bloating are common while the gut slows down; fluids, fibre and a daily walk sort out most cases within a week.
-
Some people notice taste changes, sulfur burps or mild headaches in the first weeks — these almost always settle on their own.
-
Hair shedding a few months in comes from rapid weight loss, not the drug, and reverses with enough protein, iron and B12.
-
Start low, go slow, and tell your doctor about anything severe — that single principle prevents the great majority of problems.
Who's a good candidate — and who isn't
GLP-1 weight treatment is generally for adults with a BMI of 30 or above, or 27 and above with a weight-related condition such as type 2 diabetes, PCOS, fatty liver, high blood pressure or sleep apnoea. It isn't suitable for everyone: it's avoided in pregnancy and breastfeeding, and ruled out entirely for people with a personal or family history of medullary thyroid cancer or MEN-2 syndrome. A past episode of pancreatitis or a history of eating disorders calls for extra caution. This is exactly why a proper medical assessment comes first — a doctor will tell you honestly whether it's right for you, including when the answer is no.
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.
Staying safe: genuine medication only
Counterfeit and grey-market GLP-1 is a real and growing problem across India, often sold cheaply on messaging apps and unverified websites. Fake pens can be unsterile, wrongly dosed, or contain nothing useful at all — and there have been confirmed harms in India. Protect yourself: buy only from a CDSCO-licensed pharmacy against a valid prescription, check the hologram, batch number and expiry, and treat any price far below the market rate as a warning sign. A genuine pen always comes with a traceable invoice and the dispensing pharmacist's details.
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.
Doing this the supervised way
The safest, most effective version of this is doctor-led from day one. With ZIVOLABS that means a free online assessment, a real consultation with a registered doctor, a genuine prescription, and cold-chain delivery of authentic medication — plus unlimited follow-up messaging so you're never adjusting doses or troubleshooting side effects alone. You get the medication and the plan around it: protein and movement targets, regular check-ins, and a clinician who adjusts your dose as your body responds.
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.
