Which Is Better: GLP-1 or Mounjaro? (October 2026)

Clinically reviewed by Mahommed Zunaid Ayub Patel, Superintendent Pharmacist

Reviewed Last updated Next review

Mounjaro is not an alternative to GLP-1 medicines: it activates the GLP-1 receptor and a second one, GIP. In the first large head-to-head trial, tirzepatide produced 20.2% average weight loss versus 13.7% on semaglutide 2.4mg (Wegovy) over 72 weeks.15 Both are licensed and effective; individual results vary.

A quick overview

What to know
before you start.

  • "GLP-1" is a class of medicines; Mounjaro (tirzepatide) is a dual GIP and GLP-1 medicine within that wider family.
  • SURMOUNT-5 is the first large head-to-head trial: 20.2% weight loss on tirzepatide versus 13.7% on semaglutide 2.4mg over 72 weeks.
  • Both Mounjaro and Wegovy are once-weekly, licensed treatments; the better fit depends on your health profile and prescriber advice.
  • Liraglutide-type GLP-1 products are daily injections, unlike once-weekly Mounjaro and Wegovy.
  • Trial averages do not predict your own result.
In this guide

01 · The verdict

Which suits whom: the short verdict

Mounjaro suits people who want the dual-action option; in the head-to-head trial it gave higher average weight loss. Wegovy suits people whose prescriber prefers semaglutide. Both are effective, licensed treatments, so tolerance, health history and prescriber advice matter more than the headline number alone.15 For a deeper pairing, see our guides on Mounjaro or Wegovy and Wegovy vs Mounjaro.

03 · What GLP-1 means

What "GLP-1" actually means

Tirzepatide is the first treatment of its kind to activate two gut-hormone receptors at once, GIP and GLP-1. Together these help regulate appetite, slow stomach emptying and improve the body's response to insulin. This dual action distinguishes Mounjaro from single-action GLP-1 medicines such as semaglutide.1

04 · Trial evidence

What the trials show

In SURMOUNT-1 (2,539 adults), tirzepatide with diet and exercise gave average losses of 15% on 5mg, 19.5% on 10mg and 20.9% on 15mg over 72 weeks, versus 3.1% with lifestyle changes alone.2 For someone starting at 100 kg, 20.9% is about 21 kg. In STEP 1, semaglutide 2.4mg gave 14.9% over 68 weeks versus 2.4% on placebo.9 SURMOUNT-5 is the first large head-to-head trial of the two. Individual results vary.

05 · Other options

Other alternatives

Liraglutide products such as Saxenda are daily injections supplied at 6mg per millilitre, unlike once-weekly Mounjaro and Wegovy. Supplements marketed as natural alternatives are low-cost with no clinical oversight, and dosing is not standardised. See also Ozempic or Mounjaro, Rybelsus or Mounjaro and orlistat or Mounjaro.

06 · Getting treatment

NHS or private

Mounjaro is available on the NHS, but access is being phased in over several years. NICE recommends it for adults with a BMI of at least 35 plus at least one weight-related condition, and the primary-care rollout began in June 2025 with the highest-need groups first.4 Privately, a free consultation is reviewed by a GPhC-registered prescriber, with free next-day tracked delivery and official LillyDirect supply.

How ordering works

How ordering works at EverydayMeds

Three steps, with our pharmacy team alongside you.

  1. EverydayMeds online consultation on a mobile phone

    Step 1: Online consultation — 5–10 minutes

    Complete a confidential health questionnaire covering BMI, medical history and current medication. No payment is taken until you're approved.

  2. A clinician ready to review an online consultation

    Step 2: Prescriber review — usually same day

    A UK registered prescriber checks your suitability against the licensed criteria (BMI ≥30, or ≥27 with a weight-related condition) and contraindications, and confirms your starting dose.

  3. An EverydayMeds delivery box

    Step 3: Next-day tracked delivery

    Dispensed by our GPhC-registered pharmacy in temperature-controlled packaging with needles and a sharps bin included. Orders approved by 3pm for next-day tracked delivery.

Start your free consultation

Prescription and dispatch follow clinical approval. Confirm current delivery options when ordering.

Afterwards you're not on your own: dose-change reviews are built in before each step up, our pharmacist team is available for side-effect questions, and repeat orders re-check suitability rather than auto-shipping.

Your questions, answered

Mounjaro price UK — frequently asked questions

Answers to common questions about Mounjaro prices, NHS access and ongoing treatment.

Ask our pharmacy team
Which is better, GLP-1 or Mounjaro?
Mounjaro is a GLP-1 medicine that also targets GIP, so the real comparison is with single-action options like semaglutide. In SURMOUNT-5, tirzepatide averaged 20.2% weight loss versus 13.7% on semaglutide 2.4mg over 72 weeks. Both are licensed; your prescriber helps decide which suits you.
Which is more effective, semaglutide or tirzepatide?
In SURMOUNT-5, the first large head-to-head trial, tirzepatide averaged 20.2% body weight loss against 13.7% for semaglutide 2.4mg over 72 weeks. These are trial averages, individual results vary, and both treatments work alongside a reduced-calorie diet and more physical activity.
Is there a strongest GLP-1 medicine?
No licensed medicine is best for everyone; your prescriber decides what suits you.
Is there a natural alternative to Ozempic?
Supplements marketed as natural alternatives are low-cost with no clinical oversight, and their dosing is not standardised. They are not an established equivalent to licensed medicines. Ozempic itself is semaglutide licensed for type 2 diabetes — it is not a UK weight-loss medicine; the licensed weight-management options are Mounjaro (tirzepatide) and Wegovy (semaglutide 2.4mg). Speak to a prescriber about regulated options instead.
What are the latest warnings about Mounjaro?
Only buy from a regulated pharmacy, as counterfeit medicines are a known risk; check the GPhC register. Contraception can be affected, since Mounjaro slows stomach emptying, which can reduce absorption of oral contraceptive pills. The SmPC advises switching to a non-oral method, or adding a barrier method (such as condoms), for 4 weeks after starting Mounjaro and for 4 weeks after each dose increase.1 Report side effects through the Yellow Card scheme.7 Seek immediate medical help for severe, persistent stomach pain that may spread to your back, with or without vomiting (possible pancreatitis); pain in the upper right abdomen, fever or yellowing of skin or eyes (possible gallbladder problems); or signs of a severe allergic reaction such as swelling of the face or throat and difficulty breathing.
Is Mounjaro available on the NHS?
Yes, but access is being phased in over several years. NICE recommends it for adults with a BMI of at least 35 plus at least one weight-related condition, and the primary-care rollout began in June 2025 with the highest-need groups first. Many eligible people choose regulated private treatment rather than wait.
