Wegovy Suppliers in the UK: What Official Guidance Actually Tells You

What NICE and the MHRA say about where Wegovy comes from

Wegovy received its UK licence from the MHRA for weight management in adults, and NICE published its appraisal of semaglutide for this indication in March 2023, under Technology Appraisal 875. Neither document leaves much ambiguity about the supply route: Wegovy is a Prescription-Only Medicine, and the only legal path runs from Novo Nordisk's manufacturing sites, through MHRA-licensed pharmaceutical wholesalers, to a GPhC-registered pharmacy, and then to a patient who holds a valid prescription. That chain is not optional. It exists because the concentration, sterility and cold-chain requirements of a biological injectable medicine demand it. A semaglutide pen that has left the licensed supply chain at any point (whether through a grey-market importer, an unregistered seller, or a social-media account) carries real clinical risk, regardless of how it is labelled.

From January 2026, the MHRA issued updated safety communications on GLP-1 medicines reinforcing that patients should only obtain these treatments from regulated sources. The MHRA Yellow Card scheme is the right place to report any seller you suspect is operating outside the legal supply chain.

How semaglutide suppliers serving UK patients are regulated

A question our prescribers hear most weeks is: "How do I know the pharmacy I'm ordering from is legitimate?" The answer is straightforward in principle. Every pharmacy dispensing Wegovy in the UK (whether a high-street chemist or an online clinic) must be registered with the General Pharmaceutical Council and must source medicines from licensed wholesalers. You can check any UK online pharmacy's registration number on the GPhC register in under a minute. If a premises number is not listed there, the pharmacy should not be dispensing Prescription-Only Medicines to UK patients. For online pharmacies, the GPhC also issues a logo and registration status that should appear on their website.

Novo Nordisk, as the manufacturer, does not sell directly to patients and does not operate a patient-facing ordering system. The authorised route for private patients in England is through a regulated online or in-person pharmacy, following assessment by a prescriber. Our guide to Wegovy suppliers explains what the authorised supply route involves and how to identify a pharmacy operating within it. Semaglutide suppliers serving NHS patients operate through specialist weight management services under the commissioning framework set out by NHS England, a separate route with its own referral criteria and waiting lists, explored further on our Wegovy supply in the UK page.

The counterfeit problem and what it means for choosing a supplier

The MHRA has been unambiguous: fake weight-loss pens are circulating in the UK, primarily through online marketplaces and social-media sellers. In October 2023, counterfeit pens labelled as semaglutide products were seized; analysis found some contained insulin instead of the stated medicine, leading to hospitalisations from severe hypoglycaemia. Enforcement escalated significantly through 2025, with around 20 million doses of illegally traded weight-loss medicines (approximately £45m street value) seized, and a UK manufacturing site producing counterfeit tirzepatide pens raided in Northampton. The same networks distribute fake semaglutide.

The red flags are consistent: sellers offering Wegovy or semaglutide without requiring a prescriber's assessment, prices substantially below the market range, and "discount codes" from accounts with no verifiable pharmacy registration. These are not just commercial signals; they are clinical ones. A pen from an unlicensed source may have been stored incorrectly, diluted, mislabelled, or replaced with a different substance entirely. The how Wegovy is supplied page has more detail on the cold-chain and authenticity requirements for the pen specifically.

If you are weighing up the cost of legitimate private treatment, our Wegovy prices page sets out what a compliant prescription service typically includes and why headline prices vary between providers. For a broader look at semaglutide as a medicine (including its mechanism and licensed indications) the semaglutide overview is a good starting point.

What a legitimate UK Wegovy supplier looks like in practice

A registered UK pharmacy dispensing Wegovy will always require you to complete a clinical consultation before a prescription is issued. That assessment is reviewed by a named, GPhC-registered Independent Prescriber, not automated software. Identity verification, weight confirmation, a review of your medical history and current medicines, and a check for contraindications are all part of a responsible clinical process. The pen you receive will have arrived via the licensed cold chain, stored at 2–8°C throughout, in manufacturer-sealed packaging.

At nume, our pharmacy holds GPhC premises registration 9012878, verifiable directly at pharmacyregulation.org. Medicines are sourced through Novo Nordisk's authorised UK supply routes. Every consultation is reviewed the same day by one of our prescribers, you can read about the clinical team on the clinical team page. Once approved, orders placed before 12pm are dispatched the same working day and delivered free the next working day by DPD in plain, unbranded packaging. If you have questions about how your treatment might change over time, including whether you can stop Wegovy at any time, our prescribers can talk you through your options during your consultation. If you'd like to explore whether Wegovy is clinically suitable for you, the right place to start is a free consultation with our prescribers.
