How to buy the Wegovy step-up dose 1mg legally in the UK

What the NICE guidance says about reaching 1mg safely

NICE's recommendation for semaglutide (TA875) is grounded in a titration protocol where dose increases happen at prescribed intervals under clinical supervision. The 1mg step is not a starting dose — it follows the 0.25mg and 0.5mg phases, each held for approximately four weeks to allow your body to adjust. That graduated schedule exists because the STEP 1 trial, published in the New England Journal of Medicine, was run under exactly those conditions: slow escalation, consistent oversight, lifestyle support alongside. The weight-loss results in that trial (around 15% average body-weight reduction over 68 weeks at the 2.4mg maintenance dose) are inseparable from how the dose was managed. Skipping phases, sourcing doses without clinical review, or purchasing from an unverified seller breaks that framework entirely. The MHRA has been direct on this point in its public guidance on GLP-1 medicines, and the evidence for doing it properly is the strongest argument for doing it through a regulated pathway.

If you want to understand where 1mg sits in relation to the full sequence, our overview of Wegovy steps in order maps out each phase clearly.

The only legal route to a prescription in the UK, and how nume fits in

Semaglutide is a Prescription-Only Medicine under the Human Medicines Regulations 2012. That means a registered prescriber must assess you, judge you suitable, and issue a prescription before a pharmacy can dispense any dose, including 1mg. There is no shortcut that is also legal. At nume, the process runs like this: you complete a free online consultation covering your health history, current medicines, BMI and weight-related conditions. A GPhC-registered Independent Prescriber (a real clinician, not automated software) reviews that consultation the same day. If they approve your treatment, the pharmacy dispenses and dispatches it. Order before 12pm Monday to Friday and it leaves the same day; DPD delivers the next working day, tracked, in unbranded packaging. Before committing to any online pharmacy, you can confirm it is GPhC-registered by searching the GPhC pharmacy register, that check takes about thirty seconds and is worth doing. nume's entry is number 9012878.

Fake pens, social-media sellers and why 1mg is a particular target

Step-up doses like 1mg are actively traded by unverified sellers because patients already on Wegovy need them to continue titrating, and demand is predictable. The MHRA has seized large quantities of fake weight-loss pens from unregulated sources, counterfeit pens have been found to contain insulin rather than semaglutide, which carries serious clinical risk. Red flags are consistent: sellers offering doses without a prescription, prices far below the private market rate, discount codes or voucher promotions tied to a prescription medicine. If you are ready to move forward through the titration schedule, you can buy the Wegovy step-up dose at 0.5mg through a regulated pathway before progressing to 1mg. Report suspect sellers at yellowcard.mhra.gov.uk. The main Wegovy buying guide covers the full legitimacy checklist if you want to work through it systematically.

One practical note: once your 1mg pen arrives, store it in the fridge door (2 to 8°C) away from the freezer shelf. Check the Patient Information Leaflet for the exact room-temperature window if you need to travel with it; do not rely on secondary sources for storage times.

Eligibility at the 1mg stage, what the prescriber is checking

If you are already titrating through Wegovy, you will have had an initial assessment. For the 1mg step specifically, a prescriber reviewing a repeat or transfer request will want evidence that you have completed the prior dose phase as directed and that you have not experienced side effects that make moving forward clinically unsuitable. For new patients, the licensed criteria for semaglutide cover adults with a BMI of 30 or above, or 27 to 29.9 with at least one weight-related condition such as hypertension, type 2 diabetes, high cholesterol or obstructive sleep apnoea. BMI thresholds are 2.5 kg/m² lower for South Asian, Chinese, Middle Eastern, Black African or African-Caribbean backgrounds under UK guidance. BMI alone does not guarantee approval; the prescriber weighs the complete picture. Patients transferring from another provider will be asked for evidence of their current treatment and dose, and those who are ready can buy Wegovy 1mg once a prescriber has confirmed it is the appropriate next step. Our clinical team applies the same standard to every review, whether it is a first consultation or a repeat at a step-up dose. Questions about the process are answered on our FAQs page, and the weight-loss treatment overview gives the broader context on which medicines we prescribe and why.
