Getting the most out of Wegovy: the legal, safe route in the UK

You've done the research, here's where that actually leads

Most people who land on this page have already spent time reading about Wegovy. You know roughly how it works, you've seen the clinical trial figures, and you've probably weighed up whether it's right for you. What you might be less sure about is what happens next, specifically, how you get from 'interested' to 'holding the pen'.

The short answer is that in the UK there is one legal route: a prescription from a qualified prescriber, issued after a genuine clinical assessment. There is no shortcut, and that is a good thing. The NHS guidance on semaglutide is clear that this is a prescription-only medicine requiring clinical oversight. Any seller offering Wegovy without that assessment is operating outside UK law, and the risks are serious, more on that below.

Through a regulated online pharmacy, the process is more straightforward than many people expect. You complete a structured health questionnaire that covers your BMI, any relevant medical conditions, current medications, and your weight history. A prescriber reads every answer. If semaglutide is clinically suitable, a prescription is issued and your treatment is dispensed from a GPhC-registered pharmacy. If it is not the right fit, you are told clearly and, where possible, pointed towards alternatives. Either outcome is the correct one.

Feeling uncertain about whether you'll qualify is completely understandable. Many people assume the bar is higher than it is, or worry that their GP's reluctance to discuss weight medicine privately reflects the likelihood of being approved. It often doesn't. If you are wondering whether the starting dose is currently available, you can check whether Wegovy 0.25 is in stock before you begin.

How to check the pharmacy you're using is genuinely registered

Before you hand over personal health information or payment details to any online pharmacy, one check takes about thirty seconds and tells you everything you need to know. The GPhC register is publicly searchable, and every legitimate UK online pharmacy dispensing prescription medicines must appear on it. Search by name or registration number. If a pharmacy is not listed, stop there.

nume's GPhC premises registration number is 9012878, you can verify that directly on the register. The medicines are sourced through the licensed UK supply chain, with authorised supplier relationships with Eli Lilly and Novo Nordisk.

The MHRA has issued repeated warnings about counterfeit weight-loss pens sold through social media and unregistered websites. Fake pens have been found to contain the wrong substances entirely, including insulin in some cases. In October 2025, enforcement teams raided the first UK site illegally manufacturing counterfeit tirzepatide pens, and around 20 million doses of illegally traded weight-loss medicines (approximately £45m street value) were seized across 2025 alone. A price that seems unusually low, a seller operating without a prescription process, or a 'discount code' tied to a weight-loss injection are all red flags. Report any suspect seller through the MHRA's Yellow Card scheme.

Knowing the route is safe is part of getting the best from treatment. A pen from an unverified source is not just a legal problem, it is a clinical one.

Who the licence covers and what the assessment looks at

Wegovy is licensed in the UK for adults with a BMI of 30 or above, or a BMI of 27 to 29.9 alongside at least one weight-related health condition such as high blood pressure, high cholesterol, prediabetes, or obstructive sleep apnoea. Lower BMI thresholds apply for some ethnic backgrounds under UK clinical guidance. BMI alone does not guarantee approval, the prescriber reviews the full picture, including your current medications, any conditions that might affect safety, and whether any contraindications apply.

The NICE appraisal of semaglutide (TA875) sets out the NHS criteria, which are stricter than the licensed criteria and require access through a specialist weight management service for a maximum of two years. Private treatment through a regulated pharmacy uses the licensed criteria (which is a broader population) and does not require a specialist referral or an NHS waiting list.

At nume, the prescriber's review covers identity verification, live weight confirmation on video, a check of your Summary Care Record where appropriate, and a review of any evidence you provide if you are transferring from another provider or requesting a dose increase. Every repeat order goes through the same clinical review before anything is dispatched.

Starting treatment: what happens after approval

Once a prescriber confirms suitability and issues a prescription, your treatment is dispensed by our GPhC-registered pharmacy and dispatched the same day if your order arrived before 12pm on a working day. DPD delivers the following working day, tracked, in packaging that gives nothing away. Wegovy requires refrigerated storage, so the delivery is handled to protect the medicine.

Getting the most out of Wegovy also means having support beyond the first pen. Nausea, changes in appetite, and questions about what to eat are all normal at the start of treatment, and our prescribers are available for aftercare seven days a week. One price covers everything: consultation, prescription, treatment, delivery, and ongoing clinical support. There are no subscription commitments. Every repeat order is clinically re-reviewed before it goes out. Our guides on how to get the golden dose out of your Wegovy pen and how to get an extra dose out of a Wegovy pen are worth reading once you have started, so you can be confident you are using each pen correctly.
