Who Can Legally Sell Semaglutide in the UK

What UK law actually says about who may supply semaglutide

The starting point is the Human Medicines Regulations 2012. Under those rules, semaglutide (whether as Wegovy injection or, following its MHRA approval in June 2026, the Wegovy tablet) is classified as a Prescription-Only Medicine (POM). That classification means two things in practice: first, a registered prescriber must assess the patient and issue a prescription; second, only a GPhC-registered pharmacy may dispense against that prescription. Neither step can be skipped, and neither can be performed by an entity that sits outside those regulatory frameworks.

The MHRA, which licenses medicines in the UK, is clear that GLP-1 medicines are not assessed for quick or cosmetic use, they are licensed for defined clinical indications, and supply must follow a proper clinical pathway. You can read the government's own guidance on this at GOV.UK's GLP-1 medicines guidance. The NICE appraisal of semaglutide for weight management, TA875, reinforces the same point: access is conditional on clinical criteria being met, not on a patient simply wanting the medicine.

Practically, this means the pool of legal sellers is straightforward to define: NHS specialist weight management services, GP practices now authorised to prescribe under the 2026/27 GP contract, and GPhC-registered online and high-street pharmacies operating with a valid prescribing pathway. That is the complete list. Social-media accounts, unverified websites, gym suppliers and marketplaces do not qualify, regardless of how convincingly they present themselves.

How to check whether a pharmacy selling semaglutide is actually registered

This is the one practical habit worth building before you spend anything. Every legitimate UK pharmacy (online or bricks-and-mortar) holds a GPhC premises registration number, and the register is public. Go to the GPhC pharmacy register, type in the pharmacy's name or registration number, and a live result comes back in seconds. If a seller cannot produce a GPhC number, or the number returns no result, stop there.

Beyond the register check, look for the NHS-approved internet pharmacy logo displayed on the site (legitimate online pharmacies are required to display it) and verify that the logo links back to a real entry. A seller who asks you to complete a genuine clinical consultation, including identity verification and a review of your health history, is behaving as the regulations require. One who asks only for your card details is not.

At nume, every order involves photo-ID verification, live weight confirmation, and a same-day read of your consultation by a GPhC-registered Independent Prescriber. Our GPhC premises registration is 9012878, verifiable directly at the register. Worth checking, as it is with any pharmacy you consider using.

The counterfeit risk: why supply chain matters as much as the seller's name

The MHRA's enforcement data makes the stakes plain. In 2025 alone, approximately 20 million doses of illegally traded weight-loss medicines (worth around £45 million) were seized, and UK investigators raided the first known domestic manufacturing site producing counterfeit tirzepatide pens. Fake semaglutide pens have been found to contain insulin, a substance that, injected without clinical supervision, can cause life-threatening hypoglycaemia.

The red flags to watch for: a seller offering semaglutide without a prescription, prices far below the market range, discount codes advertised on social media, and no visible clinical assessment step. Any of these should stop you. If you encounter a suspect seller, you can report them directly via the MHRA's Yellow Card scheme, which handles both adverse reactions and concerns about illegal supply.

If you want to understand whether semaglutide is appropriate for your own situation before anything else, the clinical eligibility criteria are a sensible place to read first. And if you're weighing up where to access treatment safely, our guide to buying Wegovy in the UK covers the legitimate routes in detail.

What a legitimate clinical assessment looks like, and what to do next

A lawful semaglutide prescription follows a recognisable pattern. A clinician reviews your BMI, your weight-related health conditions, your other medicines, and your medical history. They check for contraindications, a personal or family history of medullary thyroid carcinoma, a history of pancreatitis, pregnancy, or being under 18 are among the reasons a prescriber might not proceed. Only then is a prescription issued, and only then does the pharmacy dispense.

Detailed BMI thresholds for Wegovy are covered on the semaglutide BMI eligibility page, and if you'd like a closer look at how BMI is used to determine semaglutide eligibility, that page walks through the calculations and thresholds in full. For patients who may qualify at a lower threshold, there is also specific guidance on accessing semaglutide with a BMI of 25, which explains the additional clinical criteria that apply in those cases. For a broader picture of the licensed criteria, the overview of who can use semaglutide walks through the full picture. And if you'd like to see an overview of the weight-loss treatments nume (sorry, that we offer at nume) the weight management treatment page sets out the options clearly.
