How to get microdose semaglutide in the UK: what the term actually means, and the legal route to treatment

The "microdose" misconception, and what the licensed schedule actually looks like

The word "microdose" appears in weight-loss circles to describe starting on a very low amount of semaglutide, sometimes sub-licensed quantities promoted by unregulated sellers. It is worth letting that idea go gently, because the licensed schedule for Wegovy already builds in a cautious, gradual start.

Wegovy's approved pathway begins at 0.25mg weekly, a deliberate introductory step designed to let the body adjust before the dose climbs. From there, a prescriber moves the dose upward in stages (through 0.5mg, 1.0mg and 1.7mg) with around four weeks at each level before reaching the 2.4mg maintenance dose. The higher 7.2mg option, approved by the MHRA in January 2026 and available as a dedicated single-dose pen from April 2026, sits at the other end of that range for eligible patients. The full Wegovy treatment overview walks through each stage in more detail.

The point is that licensed semaglutide for weight management already starts low. A prescriber who understands your history will titrate appropriately, which is a far safer arrangement than sourcing an unlicensed preparation from an unverified seller. If you are considering how to buy semaglutide through a regulated pharmacy, the NHS medicines information for semaglutide outlines the standard schedule clearly and is worth reading alongside any consultation: NHS semaglutide guidance.

Why a UK prescription is the only safe route to semaglutide

Semaglutide is a prescription-only medicine under UK law. The only legal way to obtain it for weight management is through a valid prescription, issued by a registered prescriber who has assessed your suitability. There is no shortcut, and the consequences of going outside this route can be serious.

The MHRA has been explicit about the risks of buying weight-loss injections from unverified online sellers. Around £45 million worth of illegally traded weight-loss medicines (roughly 20 million doses) were seized in 2025 alone, and counterfeit pens have been found to contain insulin rather than the labelled medicine. That is a clinical emergency waiting to happen. The MHRA Yellow Card scheme accepts reports of suspect sellers as well as side effects, if you encounter something that looks wrong, that is the right place to flag it.

When you approach any online pharmacy for a weight-loss medicine, the first check is straightforward: look them up on the GPhC register at pharmacyregulation.org/registers. A registered pharmacy will have a GPhC premises number you can verify in seconds. That check costs nothing and tells you immediately whether the service is regulated. Red flags include sellers offering semaglutide without a prior clinical assessment, prices dramatically below the market range, and discount codes tied to what are labelled prescription medicines.

How getting semaglutide through nume actually works

Once you have established you want a regulated UK route, the process at nume is straightforward. You complete a free health questionnaire, covering your weight history, relevant conditions and any medicines you currently take. A GPhC-registered Independent Prescriber reads your answers the same day. Not a form-scoring system. A named clinician. Our clinical team oversees prescribing across the service.

Before approval, your identity is verified with photo ID and your current weight is confirmed on a video call. This is not bureaucracy for its own sake, it is what responsible prescribing for a weight-management medicine looks like. More on how we operate explains the full safety infrastructure, including GP notification in line with GPhC guidance.

If the prescriber confirms suitability, orders placed before 12pm Monday to Friday are dispatched the same day. Your pen arrives with DPD the next working day, tracked, in unmarked packaging. After that, our aftercare team is available seven days a week, and every repeat order goes through a fresh clinical review before anything is sent. No auto-renewals, no rolling subscription that dispatches without anyone looking at your progress.

People who have been on treatment elsewhere and want to transfer can do so, though we ask for evidence of your current dose before any increase is approved. How ordering semaglutide works covers the transfer process in more detail.

Who the licensed criteria cover (and what to expect from the assessment

The licensed eligibility for Wegovy (semaglutide for weight management) applies to adults with a BMI of 30 or above, or a BMI of 27 or above where at least one weight-related 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 clinical guidance.

Meeting those numbers is a starting point, not a guarantee. The prescriber is assessing the complete picture: your medical history, any contraindications, your current medicines and whether this treatment is appropriate for you specifically. Understanding how to get prescribed semaglutide can help you prepare for that conversation, particularly if you have complex medical history or are currently taking other medicines. Semaglutide is not recommended during pregnancy, while breastfeeding, or when trying to conceive, and it is not licensed for under-18s.

If you are trying to work out whether you might qualify before beginning a consultation, the NHS BMI calculator is a useful starting point, and our weight loss treatment overview sets out what the assessment considers. The NICE appraisal of semaglutide for weight management (NICE TA875) is also publicly available if you want to read the clinical evidence base. For eligibility questions specific to the NHS route, our semaglutide on the NHS page explains the current access criteria and waiting list reality. If you have decided a private route is right for you, our guide to ordering Wegovy online safely covers what a compliant process should include from start to finish.
