Buying Weight Loss Injections Legally and Safely in the UK

Step 1, Complete a free medical consultation online

Every legitimate journey to a weight loss injection starts here. You fill in a structured medical questionnaire covering your weight, health history, current medications and any relevant conditions. At nume, this goes directly to a GPhC-registered Independent Prescriber who reads it personally, your consultation lands on a clinician's desk, not in an automated queue. That review happens the same day.

Photo-ID verification and live weight confirmation via video are part of the process. These steps are not bureaucracy for its own sake; they exist because the prescriber needs accurate information to make a safe decision. Patients transferring from another provider are asked for evidence of their current treatment and most recent dose. If you have questions about what to expect during the consultation, our FAQs cover the most common ones.

BMI ≥30 is the standard starting threshold under the licensed indications for both Mounjaro and Wegovy. A BMI of 27 or above may qualify if you also have a weight-related condition such as high blood pressure, type 2 diabetes, high cholesterol or obstructive sleep apnoea. Lower BMI thresholds of 2.5 kg/m² apply for South Asian, Chinese, Middle Eastern, Black African or African-Caribbean backgrounds under UK clinical guidance. BMI alone, though, is never the whole picture, the prescriber weighs the full clinical context before deciding.

Step 2, Prescription issued and treatment dispatched

If the prescriber decides treatment is clinically appropriate, they issue a prescription through our GPhC-registered pharmacy. There is no separate prescription fee, no delivery charge and no subscription to sign up to. One price covers everything. Order confirmed before 12pm on a weekday and your pen is dispatched the same day, arriving with DPD the next working day in packaging that gives nothing away, useful whether you live with others or simply prefer discretion.

Your pen will need to go straight into the fridge when it arrives; keeping it on the shelf next to the milk in the fridge door is a practical habit many patients settle into. For the exact storage window and any room-temperature allowance, the Patient Information Leaflet inside the box is the definitive source, our prescribers will flag anything specific to your treatment. You can read more about the treatments we prescribe and how to get started on our treatment page.

Every repeat order goes through the same clinical re-review. There are no auto-renewals; a prescriber checks your progress before each new supply.

Step 3 (Verify any pharmacy before you pay

Before you buy weight loss injections online from any pharmacy, including nume, you should check it is on the GPhC register. The General Pharmaceutical Council maintains a publicly searchable register of every registered pharmacy premises in Great Britain. You can verify nume's GPhC registration directly on the GPhC website; our premises registration number is 9012878. A pharmacy that cannot point you to its GPhC entry is a pharmacy you should walk away from.

The NHS England guidance on weight management injections also sets out what regulated services are expected to provide, worth reading if you are comparing your options. Our clinical team and service model are described in full if you want to understand how we are set up before starting.

Step 4, Know the red flags (and why they matter)

The MHRA has issued repeated warnings about counterfeit weight loss pens sold online and via social media. Fake pens have been found to contain insulin rather than the stated medicine, with serious consequences for those who used them. In 2025 alone, around 20 million doses of illegally traded weight loss medicines (worth roughly £45m) were seized, and the MHRA identified the first illicit UK site manufacturing counterfeit tirzepatide pens. You can report suspect sellers directly to the MHRA via the Yellow Card scheme.

The clearest red flags: a seller offering these medicines without a prescription or clinical assessment, prices far below the current UK market, and discount codes from sources you cannot verify against the GPhC register. If you come across sellers claiming to supply Mounjaro or Wegovy without a proper assessment, the risks involved are covered in more detail here. Buying through an unverified source also means there is no prescriber to call when you have a question at 7pm on a Saturday, aftercare matters for a medicine you take every week.

For context on how NHS access to these injections works and whether you might qualify through your GP, the NHS route and its eligibility criteria are explained separately.
