Can You Get Weight Loss Injections Online in the UK?

The decision starts with the prescription, not the checkout

When people search for ways to get weight loss injections online, the question underneath is usually practical: how do I start, and how quickly? The honest answer is that the prescription comes first, and everything else follows from it. Under the Human Medicines Regulations 2012, Mounjaro and Wegovy cannot be legally supplied without a valid prescription from a qualified prescriber. That isn't a bureaucratic hurdle, it reflects the fact that both medicines interact with other conditions and drugs in ways that need a trained eye to spot.

A legitimate online pharmacy handles this entirely within the same journey. At nume (sorry, at our pharmacy) you fill in a clinical questionnaire, and a GPhC-registered Independent Prescriber reads your answers and medical history the same day. Not software. A real clinician, making a considered decision. If they approve your treatment, your pen is dispatched before the end of the day (orders placed before 12pm, Monday to Friday) and delivered free the next working day by DPD, tracked and in plain packaging. The weight loss injection itself arrives ready to use with the Patient Information Leaflet inside.

Timing matters to people more than clinics realise. Plenty of patients tell us they finally got around to starting in January, or after payday, or just before a holiday they'd been putting off. Whatever the prompt, the process is the same: clinical review first, treatment after.

What separates a safe online route from a risky one

The MHRA has issued repeated public warnings about fake weight-loss pens sold online, the Yellow Card scheme allows anyone to report a suspect seller, and enforcement through 2025 saw roughly 20 million doses of illegally traded medicines (around £45 million street value) seized, including a counterfeit tirzepatide manufacturing site raided in the UK. Some fake pens contained insulin rather than the labelled medicine, with serious consequences for patients. This is not a theoretical risk.

The markers of a legitimate service are straightforward. The pharmacy should appear on the GPhC register, you can search by name or registration number. It should require a clinical assessment before prescribing, verify your identity, and be clear about what happens if you have a question after your treatment arrives. If a seller is offering these injections without any clinical assessment, pricing them far below the typical private market, or advertising discount codes for prescription medicines, those are red flags worth taking seriously. For more detail on spotting a trustworthy provider, our guide to finding the best place to get weight loss injections online covers what to check.

Counterfeit risk aside, buying through an unregistered source also means no clinical oversight if something goes wrong, no prescriber to call, no aftercare, no record in a regulated system.

Who these medicines are licensed for online or otherwise

Both Mounjaro and Wegovy are licensed for adults in the UK. The private eligibility criteria, drawn from each medicine's Summary of Product Characteristics, centre on BMI: broadly, a BMI of 30 or above, or 27 and above alongside at least one weight-related condition such as high blood pressure, type 2 diabetes, high cholesterol or obstructive sleep apnoea. Lower thresholds apply for some ethnic backgrounds under UK clinical guidance. BMI alone isn't the whole picture, the prescriber reviews your full health profile, including any medicines you already take.

Neither medicine is recommended during pregnancy, while breastfeeding, or if you are actively trying to conceive. They are not licensed for anyone under 18. Certain conditions, including a history of medullary thyroid carcinoma or pancreatitis, require careful discussion with a prescriber before starting. The NHS's tirzepatide information page sets out the full list of contraindications in plain language if you want to read ahead of a consultation.

If you're weighing up your options more broadly, the practical steps for getting weight loss injections covers both the NHS and private routes side by side, including what the current NHS phasing means for eligibility timelines.

What to expect from costs and the process once you're ready

Private treatment costs vary between providers and between doses. Since Eli Lilly adjusted Mounjaro's UK list price in September 2025, typical private prices across the market have ranged roughly from £149 to £375 per month depending on the dose and the provider. For context on what those figures include (or don't) our cost breakdown for weight loss injections explains what to look for when comparing quotes.

At nume, one price covers the consultation, the prescription, the medicine, and free next-working-day delivery. There are no subscriptions and no auto-renewals; every repeat order goes through a fresh clinical review. The aftercare team is available seven days a week.
