Is Mounjaro stronger than Wegovy?

Current evidence suggests Mounjaro may be more effective for many people. In clinical studies, tirzepatide has shown greater average weight loss than semaglutide. However, stronger does not always mean better for every person. Individual response, medical history, and tolerability all matter.

Is Wegovy cheaper than Mounjaro in the UK?

Prices vary depending on the provider, dose, and supply. In the UK, Wegovy and Mounjaro are often similarly priced, though this changes regularly. It is always worth comparing regulated pharmacies and checking the full monthly treatment cost, not just the starting dose.

Which is better for perimenopause weight gain?

Both can be helpful for perimenopause-related weight gain. If appetite changes, cravings, insulin resistance, or central weight gain are major factors, Mounjaro may offer an advantage for some women. Wegovy is also highly effective and may suit those who prefer a more established single GLP-1 option. A personalised medical review is the best way to decide.

Can you switch from Mounjaro to Wegovy or vice versa?

Yes. Some people switch between Mounjaro and Wegovy due to side effects, results, supply issues, or cost. Switching should always be done under prescriber guidance as dose conversion is not always direct and you may need to restart at a lower dose to reduce side effects.

Mounjaro vs Wegovy: What’s the Difference — And Which One’s Right for You?

Weight loss medications have been in the spotlight lately, and for good reason — they're changing lives. But with all the buzz around names like Mounjaro and Wegovy, it's easy to get confused. Are they the same thing? Are they safe? And how on earth do you choose?

Let's break it down — science, hormones, studies and all — so you can make an informed choice that works for your body, not against it.

1. Let's talk about GLP-1s: what even are they?

GLP-1 stands for glucagon-like peptide-1 — a mouthful, we know, but stay with us. It's a hormone your body naturally produces in your gut in response to food. GLP-1 has three key jobs:

→	It slows down how fast your stomach empties, so you feel fuller for longer.

→	It signals to your brain that you're satisfied.

→	It helps your pancreas release insulin, which regulates blood sugar.

GLP-1 medications mimic this hormone to support appetite regulation, reduce cravings, and improve blood sugar control — all without the intense mental effort of constant willpower.

So no, it's not "just a willpower issue." These medications work on your biology, not your character.

2. Meet the hormone crew: glucagon, GIP, and friends

If GLP-1 is the lead singer, glucagon and GIP (glucose-dependent insulinotropic polypeptide) are the backing vocalists that make the whole performance stronger.

→	Glucagon raises blood sugar levels when needed and promotes fat burning.

→	GIP helps the pancreas release insulin and may reduce appetite, but also helps the body store fat — which is why combining it with GLP-1 is game-changing.

This is where Mounjaro enters the chat.

3. Wegovy vs Mounjaro: what's the real difference?

Both are weekly injectable medications, but the hormones they target set them apart:

→	Wegovy (semaglutide) is a GLP-1 receptor agonist. It mimics the GLP-1 hormone.

→	Mounjaro (tirzepatide) is a dual agonist, mimicking both GLP-1 and GIP — sometimes called a "twincretin".

With Wegovy

Appetite suppression, slower digestion, and better blood sugar control.

With Mounjaro

All of the above, plus enhanced fat-burning and insulin regulation thanks to the GIP effect.

It's not about which one is "better" — it's about how your body responds.

4. What do the studies actually say?

Let's talk evidence — because we know you want more than just marketing hype.

13.7%Average body weight lossWegovy (semaglutide) — NEJM 2021, Wilding et al.

20.2%Average body weight lossMounjaro (tirzepatide) — NEJM 2022, Jastreboff et al.

Both Mounjaro and Wegovy are approved for weight management in people with a BMI of 30 or above, or 27 or above with at least one weight-related health condition.

5. Mounjaro vs Wegovy: side-by-side comparison

Let's not pretend this is a one-size-fits-all decision. Here's how they compare across the questions that matter most.

Question	Mounjaro (tirzepatide)	Wegovy (semaglutide)
What BMI is eligible?	BMI ≥30, or ≥27 with at least one weight-related condition (e.g. hypertension, dyslipidaemia, sleep apnoea, cardiovascular disease, prediabetes, or type 2 diabetes).	BMI ≥30, or ≥27 with at least one weight-related condition (e.g. hypertension, dyslipidaemia, sleep apnoea, cardiovascular disease, prediabetes, or type 2 diabetes).
Which causes more weight loss?	Average 20.2% body weight loss on tirzepatide in clinical trials.	Average 13.7% body weight loss on semaglutide in clinical trials.
Which has more side effects?	Similar GI side effects to Wegovy. Some people report stronger appetite suppression and more digestive symptoms during dose increases, but tolerance varies.	Well-established GI side effect profile. Some find it easier to tolerate. Individual response matters more than the brand itself.
Which suits women in perimenopause?	May be particularly useful for menopause-related weight gain, increased appetite, insulin resistance, or central weight gain. Good option where weight loss goals are higher.	A strong option for midlife weight gain, especially if appetite control is a key issue and a more established single GLP-1 medication feels preferable.
Which is better for appetite, cravings, or insulin resistance?	Often considered the stronger option when food noise, cravings, and insulin resistance are major drivers. Its dual GIP/GLP-1 action may offer greater metabolic benefits for some.	Very effective for appetite reduction and cravings. If insulin resistance or severe hunger are dominant issues, Mounjaro may have an edge — but Wegovy remains a strong option.

6. How to choose safely

Choosing between Mounjaro and Wegovy should always start with a proper medical assessment. The safest option depends on a number of things:

→	Your BMI, medical history, and current medications

→	Any history of gallbladder or pancreatic problems

→	Pregnancy plans, eating patterns, and hormonal factors

→	Whether insulin resistance, menopause-related weight gain, or strong appetite drive are present

→	Side-effect tolerance, cost, and your ability to commit to lifestyle changes alongside treatment

The best medication is not simply the strongest one. It is the one that is safest, sustainable, and appropriate for you. Always use a regulated prescriber and a licensed pharmacy — like TribElle.
