Where Can I Buy GLP-1 and GIP/GLP-1 Receptor Agonist Drugs in the UK? (October 2026)

01 · How to buy

Where you can legally buy these medicines

The legal routes are an NHS prescription or a registered private pharmacy. 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 Many people who meet the licensed criteria choose regulated private treatment rather than waiting.

Privately, you can order the Mounjaro pen from us. All six doses are in stock. You can also see our Wegovy pen, and every option on our weight loss treatments page. For a wider look at costs, see GLP-1 receptor agonists cost.

02 · Ordering

How ordering works

• Complete the free online consultation, a short health questionnaire with no obligation.
• A GPhC-registered prescriber reviews it. 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 registered pharmacy dispenses; same-day dispatch applies when ordered by 3pm, with free next-day tracked delivery in temperature-controlled packaging.

New customers save £40 on their first order with code FIRST40, and an automatic £25 reorder discount applies to every future order (code DOSE25). Our Mounjaro comes through official LillyDirect supply, and Klarna and pay-monthly options are available with no subscription.

03 · GLP-1 versus GIP/GLP-1

GLP-1 versus GIP/GLP-1 medicines

Tirzepatide activates two gut-hormone receptors at once, GIP and GLP-1, which distinguishes Mounjaro from single-action GLP-1 medicines such as semaglutide (Wegovy/Ozempic).¹ Read more on how GLP-1 receptor agonists work and on dual GIP/GLP-1 agonists.

Mounjaro is licensed for weight management in adults with a BMI of 30 or above, or 27 to 30 with at least one weight-related condition. It is used alongside a reduced-calorie diet and increased activity, and a prescriber assesses suitability first.¹

04 · Avoiding fake pens

Avoiding counterfeit pens

The MHRA has seized thousands of fake weight-loss pens in the UK and has issued alerts after falsified Mounjaro pens were identified. Fake pens have caused hospitalisations, and some contained insulin rather than tirzepatide.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.

A genuine pen has a batch number and expiry date, arrives cold-chain packaged, and the solution is clear and colourless. Do not use one that looks cloudy, has particles or is past expiry.¹³

05 · Gelatin and over-the-counter claims

Over-the-counter and "poor man's Ozempic" claims

There is no over-the-counter version of Ozempic. Ozempic is semaglutide licensed for type 2 diabetes only; it is not a UK weight-loss medicine, and a regulated UK pharmacy will not supply it for weight loss. Supplements marketed as "nature's Ozempic" are low-cost products with no clinical oversight, and they are not the same medicine. If you are weighing a GLP-1 gelatin product, treat dramatic weight-loss claims with caution. Anyone offering prescription injections without a consultation or prescription is not operating legally.
