02 · Comparing

How to compare Mounjaro 7.5mg prices

Compare the same dose, the same month and what is included. Across the UK pharmacies we track (checked 10 October 2026), the gap between providers for the same dose runs from £27 to £41. Boots lists Mounjaro doses at standard prices from £179.00 to £339.00.

Check four things before choosing:

• Is the quoted price a first-order price or the standard repeat price?
• Is delivery free and cold-chain packaged? Ours is free next-day tracked delivery.
• Is a prescriber review included, with ongoing monthly reviews?
• Can you verify the pharmacy on the GPhC register? We are registration 9012878.

A lower headline price from an unverified seller is not a saving. See our Mounjaro best price UK guide for the wider picture, or the Mounjaro discount code page for how the offers work.

04 · Ordering

How ordering works

• Free online consultation: a short health questionnaire, no charge and no obligation. Start your free consultation.
• Prescriber review: a GPhC-registered prescriber reviews your order. Payment is taken when you place the order; if the prescriber decides the treatment is not suitable, the order is refunded automatically in full.
• Dispatch and delivery: same-day dispatch when ordered by 3pm, then free next-day tracked delivery in temperature-controlled packaging. Saturday delivery is £14.99.

Klarna and pay-monthly options are available, with no subscription lock-in. Repeat orders re-check suitability and never auto-ship.

05 · Who 7.5mg suits

Who Mounjaro 7.5mg is for

Mounjaro comes as a pre-filled KwikPen in six strengths: 2.5mg, 5mg, 7.5mg, 10mg, 12.5mg and 15mg.¹ 7.5mg sits in the middle of the ladder, so it is a step-up dose rather than a starting one. A prescriber decides whether to move you up based on how you are responding and tolerating treatment.¹¹

Licensing for weight management covers adults with a BMI of 30 or above, or 27 to 30 with a weight-related condition such as high blood pressure, prediabetes or type 2 diabetes. It is used alongside a reduced-calorie diet and increased physical activity. A prescriber assesses your BMI, history and current medicines first.¹ Our Mounjaro 7.5 complete guide covers the dose in more depth.

06 · What results to expect

What results can you expect?

In the SURMOUNT-1 trial of 2,539 adults, people taking tirzepatide alongside diet and exercise lost on average 15% of body weight on 5mg, 19.5% on 10mg and 20.9% on 15mg over 72 weeks, compared with 3.1% with lifestyle changes alone.² These are trial averages and individual results vary. For someone starting at 100 kg, 20.9% is about 21 kg.

Treatment works alongside a reduced-calorie diet and more activity, not instead of them.

07 · Avoid fake pens

Cheap Mounjaro and counterfeit risk

The MHRA has seized thousands of fake weight-loss pens in the UK and issued alerts after falsified Mounjaro pens were identified. Some fakes contained insulin rather than tirzepatide and caused hospitalisations.⁷ Only buy from a pharmacy you can verify on the GPhC register, never from social media, beauty salons or unverified websites.¹² Genuine treatment always involves a prescription and a clinical consultation.

Our Mounjaro is supplied through official LillyDirect supply, direct from Eli Lilly's UK distribution. Every pen carries a batch number and expiry date you can check.

08 · Saving money safely

Saving money without taking risks

The legitimate savings are the new-customer and reorder discounts.

09 · Serious side effects

Serious side effects: when to get help straight away

Serious side effects are uncommon but need urgent attention. 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/eyes (possible gallbladder problems); or signs of a severe allergic reaction such as swelling of the face or throat and difficulty breathing. If you take insulin or a sulfonylurea alongside Mounjaro, watch for low blood sugar (shakiness, sweating, confusion) — your prescriber may need to adjust those medicines.¹

10 · NHS access

NHS access to Mounjaro

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. The primary-care rollout began in June 2025 with the highest-need groups first, initially BMI 40+ with four or more qualifying conditions.⁴⁶ Full rollout will take years, which is why many people who meet the licensed criteria choose regulated private treatment.
