Wegovy for weight loss: where to buy it legally and safely in the UK

The real question isn't where to buy, it's who decides you can

A lot of people searching for where to buy Wegovy for weight loss assume the main hurdle is finding a pharmacy that has it in stock. The bigger step comes before that. Wegovy (semaglutide) is a Prescription-Only Medicine under UK law, which means a prescriber must personally assess your medical history, current health status and weight before any treatment can be supplied. No legitimate provider can skip this stage.

That assessment covers your BMI, any weight-related conditions you have, medicines you already take, and whether there are any clinical reasons semaglutide would not suit you. Only once a prescriber is satisfied that it is appropriate for you will a prescription be issued. The pharmacy then dispenses against that prescription. The steps are inseparable, and that is by design, not bureaucracy.

At nume, that assessment is free and happens online. You complete a structured medical consultation, and a GPhC-registered Independent Prescriber reads it the same day. Your identity and current weight are verified, on video, not by a tickbox. If the prescriber is satisfied, your treatment is dispatched that same day for free next-working-day delivery. If they have questions or concerns, you hear about them directly. That is what a clinically led service looks like.

The full guide to getting started on Wegovy covers the process in more detail if you want the step-by-step breakdown before you begin.

How to check whether any online pharmacy is the real thing

The GPhC (the General Pharmaceutical Council) maintains a public register of every legally operating pharmacy in the UK. Before handing over any personal or medical information to an online provider, spending thirty seconds on that register is worth doing. You can search by pharmacy name or, for any pharmacy that publishes it, by premises registration number. A legitimate provider will not mind you checking.

The MHRA has issued repeated public warnings about counterfeit weight-loss pens sold online and through social media. In one enforcement operation in late 2025, around 20 million doses of illegally traded weight-loss medicines (valued at roughly £45 million) were seized, and an illicit manufacturing site producing fake tirzepatide pens was discovered in Northampton. Fake pens have been found to contain insulin rather than the medicine on the label, with serious consequences for the people who used them. The MHRA's Yellow Card service lets you report any suspect seller.

Red flags to watch for: a seller offering semaglutide without any clinical assessment, prices that are far below what a regulated pharmacy charges, discount codes for prescription medicines, or no verifiable GPhC registration. These are not quirks of a bargain, they are signs that the supply chain is not what it appears to be.

nume's GPhC premises registration number is 9012878, verifiable directly at the GPhC register. That link goes to our specific entry, not just the search page.

Who is likely to be eligible, and what shapes that decision

Under the Wegovy licence, the medicine is approved for adults with a BMI of 30 or above, or 27 or above where at least one weight-related health condition is present, for example, high blood pressure, type 2 diabetes, high cholesterol, or obstructive sleep apnoea. Lower BMI thresholds apply for some ethnic backgrounds under UK guidance, reflecting the different health risks associated with a given BMI across populations.

Eligibility is not just a number, though. A prescriber looks at the whole picture. Certain medical histories (including a personal or family history of medullary thyroid carcinoma, or a history of pancreatitis) would need to be discussed carefully. Pregnancy, breastfeeding, and trying to conceive are situations where Wegovy is not recommended. Under-18s are not within the licensed population.

NICE's appraisal of semaglutide for weight management sets out the criteria the NHS applies, which are more restrictive than the licence, requiring use within a specialist service and capping treatment at two years. Private treatment through a regulated pharmacy operates under the licensed indications rather than NICE's NHS commissioning criteria, which is why many people who do not meet the NHS threshold, or who do not want to wait, choose to buy Wegovy for weight loss privately through a regulated service. Our overview of what a Wegovy clinic involves sets out what that looks like day-to-day.

If you are currently taking semaglutide elsewhere and want to transfer, a prescriber can review your existing treatment records. The Wegovy treatment page covers what to bring to that conversation.

Why the legitimate route matters more than the price

There is a persistent misconception that the regulated route is simply a more expensive version of what you can get more cheaply elsewhere. It is not the same thing at all. A counterfeit pen from an unverified seller is not a cheaper Wegovy, it is an unknown substance in packaging that resembles Wegovy. The MHRA's enforcement data makes clear that fakes reach the UK market in significant quantities, and some have caused serious harm.

Beyond safety, there is a practical argument. A clinical assessment protects you. It identifies contraindications before they become problems. It gives you access to a prescriber if something unexpected happens. It means your dose is managed by someone who knows your history. That is what the price of a legitimate service buys you, and it is the element no discount reflects.
