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

What official guidance actually says about getting these medicines

NICE recommended tirzepatide (Mounjaro) for weight management in December 2024, and semaglutide (Wegovy) before that, but both recommendations come with a clear framework: a clinical assessment must happen first, and a prescriber (not a questionnaire algorithm) makes the call. NICE's appraisal of tirzepatide (TA1026) sets out the eligibility criteria in detail; the NHS England guidance on weight management injections covers the wraparound care that should accompany treatment. Neither document suggests these medicines can be obtained casually. The prescription requirement exists because both medicines can interact with existing conditions, affect contraception absorption, and carry a side-effect profile that needs monitoring. That is not a bureaucratic obstacle. It is the mechanism that keeps the treatment safe.

Private prescribing is entirely lawful and widely used for medicines that have long NHS waiting lists or strict NHS eligibility thresholds. A GPhC-registered online pharmacy with a named prescriber service is a legitimate, regulated option. The key is verifying the pharmacy before you hand over any personal or medical information.

How to verify any UK online pharmacy before you order

The GPhC (General Pharmaceutical Council) maintains a public register of every legally operating pharmacy in the UK. You can look up any pharmacy by its premises registration number on the GPhC register, if it is not listed, it should not be dispensing prescription medicines to UK patients. nume's GPhC premises registration is 9012878, verifiable directly at that link. Check this for any provider you are considering.

The MHRA has been unequivocal about the counterfeit risk in this market. Fake weight loss pens have been seized in significant quantities across the UK (roughly 20 million doses with a street value around £45 million) and the MHRA's warnings note that some counterfeit pens have contained insulin rather than the labelled medicine. The red flags are consistent: sellers on social media, prices far below the market rate, and medicines offered without any clinical assessment. You can report a suspect seller via the MHRA's Yellow Card scheme. That is the right call if something looks wrong.

If you are comparing providers, checking what a legitimate online service should include is a sensible first step before committing to anyone.

The step-by-step process at nume

Starting treatment through nume does not require a GP referral, a waiting list or travel to a clinic. The process is built around the clinical review, not the transaction.

First, you complete a free online consultation covering your health history, any medicines you take, BMI and weight-related conditions. A GPhC-registered Independent Prescriber then reviews everything the same day. If there is anything in your history that needs clarification, they will ask, this is not a box-ticking exercise. Identity is verified by photo ID, and weight is confirmed on a live video call. If you are transferring from another provider or requesting a dose increase, you will be asked for evidence of your current treatment; that check protects you as well as us.

Once approved, you can order weight loss injections through our regulated pharmacy, with treatment dispatched the same day if you ordered before 12pm, arriving free via tracked DPD the next working day. Orders placed on a Friday still go out the same day if submitted in time, so if payday lands on a Thursday and you want to start that week, it is genuinely possible. Packaging is plain and unbranded throughout.

Aftercare is included. Our prescribers are available seven days a week, and every repeat order triggers a fresh clinical review. There are no subscriptions and no auto-renewals; you are never committed beyond your current supply.

Who is likely to be clinically suitable

Both Mounjaro and Wegovy are licensed for adults. The licensed starting point is a BMI of 30 or above, or a BMI of 27 or above alongside at least one weight-related condition, things like high blood pressure, type 2 diabetes, high cholesterol or obstructive sleep apnoea. For some ethnic backgrounds, the relevant thresholds are 2.5 kg/m² lower under UK clinical guidance. These are the licensed parameters; the prescriber assesses the full picture, and BMI alone does not guarantee approval.

Neither medicine is recommended during pregnancy, while breastfeeding, or for anyone trying to conceive. They are not licensed for use in people under 18. If you have a history of certain gastrointestinal conditions or medullary thyroid carcinoma, those are factors the prescriber will need to know about. Eligibility is assessed individually, not by a checklist, which is precisely why the consultation matters.

If you are unsure whether NHS access might be available to you, the NHS route and current phased eligibility criteria are worth understanding first. Many people find the thresholds are strict or the waiting times are long, and private treatment through a regulated pharmacy is the practical alternative. Our clinical team can answer questions before you commit to anything.
