Weight Loss Injections with Next-Day Delivery: How It Works in the UK

Step 1: The only legal starting point is a prescription

Mounjaro (tirzepatide) and Wegovy (semaglutide) are Prescription-Only Medicines under UK law. You cannot legally obtain them without a valid prescription from a registered prescriber. That means any seller offering these medicines without a clinical assessment is operating outside the law, and very likely selling counterfeits. The MHRA has seized roughly 20 million doses of illegally traded weight-loss medicines, worth around £45 million, and raided the first UK site manufacturing fake tirzepatide pens in Northampton in October 2025. Fake pens have been found to contain insulin, with hospitalisations reported. If a price looks startling or a seller is asking nothing about your health history, treat that as a serious red flag.

The safe path is straightforward: a licensed prescriber assesses you, decides whether treatment is clinically appropriate, and issues a prescription. Only then can a pharmacy dispense and dispatch.

Step 2: Choose a pharmacy you can verify

Before entering any personal health details online, check that the pharmacy holds a valid GPhC registration. The General Pharmaceutical Council maintains a public register at pharmacyregulation.org/registers. Search by name or registration number and you'll see whether a pharmacy is actively registered and in good standing. nume's GPhC premises registration is 9012878, verifiable directly at that register. A legitimate pharmacy will make this number easy to find. One that buries it, or can't provide it, is worth walking away from.

It's also worth knowing that medicines sourced through the licensed UK supply chain come from authorised manufacturers, Eli Lilly for Mounjaro, Novo Nordisk for Wegovy. Authorised supply chains carry batch traceability that counterfeit networks cannot replicate. Our clinical team and pharmacy operate entirely within that regulated infrastructure.

Step 3: Complete a genuine clinical consultation

A real consultation for a prescription-only weight-loss medicine covers more than a BMI number. A prescriber reviews your full health picture: your weight history, existing conditions, current medicines, and whether treatment is suitable for you at all. At nume, that review is done personally by a GPhC-registered Independent Prescriber, not delegated to an algorithm, and it happens the same day you submit your answers.

The licensed eligibility criteria are broadly adults with a BMI of 30 or above, or 27 and above with at least one weight-related condition such as high blood pressure, type 2 diabetes, or high cholesterol. Lower BMI thresholds apply for some ethnic backgrounds under UK guidance. BMI alone doesn't guarantee a prescription; the prescriber makes the final clinical judgement. If you're weighing up NHS versus private routes, the NHS access criteria are more restrictive and involve waiting lists, and our guide to how weight loss injections work through the NHS explains what the referral process typically involves. Private treatment through a regulated pharmacy like ours is an option for people who don't meet the current NHS thresholds or don't want to wait.

As part of our safety process, we carry out photo-ID identity checks, live weight verification by video, and GP notification in line with GPhC guidance. Evidence is required for transfers from other providers and for dose increases.

Step 4: Same-day dispatch and next-day delivery

Once your consultation is approved, next-day delivery is the norm rather than a premium add-on. Place your order before 12pm (roughly the school-run cut-off) and your treatment ships that afternoon from our pharmacy. DPD delivers the next working day to your address, fully tracked so you can follow the parcel on your phone. Everything arrives in plain, unbranded packaging. There are no subscription commitments: every repeat order is reviewed by a prescriber before it goes out.

The price you see on our treatment page covers the consultation, prescription, medicine, and delivery, and if you'd like to buy weight loss injections through a properly regulated pharmacy, that page walks you through exactly what's included. Nothing is billed separately. If you'd like to understand how private pricing compares to what the NHS funds, including information on the newer weight loss injections now available on the NHS, our weight loss overview sets out the options plainly.

If you have questions before starting, our FAQs cover the most common ones, including a breakdown of the weight loss injections we prescribe and how they compare, and you can reach the team any day through our contact page. Our clinical lead's profile is there too, so you know exactly who oversees the prescribing process.
