How to Order Weight Loss Injections Legally and Safely in the UK

Step 1: Complete a clinical consultation — this is where everything begins

The first thing to understand is that a clinical assessment is not a formality you have to get through. It is the process that keeps you safe. Weight loss injections such as Mounjaro and Wegovy are licensed for specific groups of adults, and a prescriber needs to confirm that your BMI, health history and any current medications make treatment appropriate for you.

At nume, that consultation is free and happens online. You answer questions about your weight, your health and your goals. A GPhC-registered Independent Prescriber then reviews your answers personally the same day. The clinical team at nume also checks your identity through photo ID and confirms your weight on a live video call, which is a meaningful step that many services skip. If you are transferring from another provider, your previous treatment history is reviewed as part of the same assessment.

A common misconception worth clearing up: people sometimes assume an online consultation means a quick tick-box exercise. In practice, the prescriber is making a professional clinical decision, just as a GP would, the difference is speed and convenience, not rigour. If treatment is not clinically suitable, it will not be approved. The clinical oversight behind our service is built around that principle.

Step 2: Prescription, verification and dispatch

Once the prescriber is satisfied that treatment is appropriate, a prescription is issued and passed directly to our GPhC-registered pharmacy (registration number 9012878, verifiable on the GPhC register). Medicines are sourced through the licensed UK supply chain, with authorised supplier relationships with Eli Lilly and Novo Nordisk.

For orders placed by 12pm Monday to Friday, same-day dispatch is the target once the prescription is approved. Your treatment arrives the next working day with DPD, tracked, in packaging that gives nothing away. There are no subscription commitments. Each repeat order goes through its own clinical re-review before anything is sent out.

If you want to understand the broader landscape of where to access these medicines, including NHS routes and waiting times, our guide to where you can order weight loss injections covers that in detail. For a specific look at whether you might qualify through the NHS, our weight loss injection NHS page sets out the current eligibility criteria and phased rollout honestly.

Step 3: Know how to check any online pharmacy before you order

Ordering a prescription medicine online from an unverified source carries real risks. The MHRA has warned publicly about counterfeit weight-loss pens circulating through social media and unregulated websites, in 2025 alone, around 20 million doses of illegally traded weight-loss medicines (roughly £45m in street value) were seized, and the first illicit UK site producing fake tirzepatide pens was raided. Some counterfeit products have contained insulin rather than the stated medicine, with serious consequences for patients.

Any legitimate online pharmacy dispensing prescription medicines in the UK must be registered with the GPhC. You can check any provider at the GPhC pharmacy register in under a minute. Red flags include sellers advertising these medicines without requiring a prescription or clinical assessment, prices that seem impossibly low, and discount codes offered by unknown accounts. Suspect sellers can be reported directly through the MHRA Yellow Card scheme.

The MHRA's guidance is clear: if the offer seems to skip the clinical step, it almost certainly skips the safety step too. For a closer look at what safe ordering looks like compared to the risks, the online ordering guide is worth reading before you decide.

Who can be considered for treatment?

The private licensed eligibility criteria are set by the medicines' authorisations, not by individual pharmacies. Adults with a BMI of 30 or above, or a BMI of 27 or above alongside a weight-related health condition such as high blood pressure, type 2 diabetes, high cholesterol or obstructive sleep apnoea, may be considered. Lower BMI thresholds can apply for some ethnic backgrounds under UK clinical guidance. These figures are starting points, not guarantees. The prescriber assesses the full picture, including your medical history and any other medicines you take.

Treatment is not licensed for anyone under 18, and is not recommended during pregnancy, while breastfeeding, or if you are actively trying to conceive.
