Where to Go for Weight Loss Injections in the UK (October 2026)

01 · Your routes

Where can you get weight loss injections?

You can start with your GP, a high-street pharmacy or an online pharmacy. The table sets them side by side.

Across the UK pharmacies we track, Boots' Mounjaro pens range from £179.00 to £339.00 per month across doses, as of our index checked 10 October 2026. Across the pharmacies we track, the gap between providers for the same dose runs from £27 to £41.

02 · NHS or private

Should you go to your GP or go private?

Ask your GP first if you may meet the NHS criteria. 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 is expected to take years, which is why many people who meet the licensed criteria choose regulated private treatment.

If you go private, our free consultation is reviewed by a GPhC-registered prescriber. Payment is taken when you place the order; if the prescriber decides the treatment is not suitable, the order is refunded automatically in full. Our Mounjaro pen comes from official LillyDirect supply, with free next-day tracked delivery and same-day dispatch when ordered by 3pm. All six doses are in stock. New customers save £40 on their first order with code FIRST40, and every later order is £25 off the standard price (code DOSE25).

04 · Can you go on them?

Can I go on weight loss injections?

You may be able to if you are an adult with a BMI of 30 or above, or a BMI between 27 and 30 with at least one weight-related condition such as high blood pressure, high cholesterol, obstructive sleep apnoea, cardiovascular disease, prediabetes or type 2 diabetes. It must be used alongside a reduced-calorie diet and increased physical activity. A prescriber assesses your BMI, medical history and current medicines before deciding if it is suitable.¹

05 · Where injections go

Where do weight loss injections go on the body?

Mounjaro is injected under the skin once a week, on the same day each week, at any time of day, with or without food. Licensed sites are the stomach area (at least 5cm from the belly button), the front of the thigh, or the back of the upper arm if someone else gives the injection. Rotate the site with each dose. Each KwikPen contains four weekly doses.¹¹³ Needles, a sharps bin and injection guidance come with every order.

06 · What to expect

Is it right for you? What to expect

Everyone starts on 2.5mg weekly, which is about letting your body adjust rather than weight loss itself. After at least 4 weeks the dose rises to 5mg, then in 2.5mg steps up to a maximum of 15mg.¹

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