Semaglutide injection: how much to take, and what that means for your costs

What clinical guidance actually says about the semaglutide dose schedule

The NICE appraisal of semaglutide for weight management (TA875) describes a stepped titration: the treatment begins at 0.25mg weekly and increases roughly every four weeks through 0.5mg, 1.0mg and 1.7mg before reaching the 2.4mg maintenance dose. In January 2026 the MHRA also approved a higher 7.2mg dose for eligible adults with a BMI of 30 or above, initially delivered as three 2.4mg pens weekly and later as a dedicated single-dose pen approved in April 2026. The STEP 1 trial, published in the New England Journal of Medicine, found an average weight reduction of around 15% over 68 weeks at 2.4mg.

This phased structure is clinically deliberate: starting low reduces the likelihood of nausea and other gastrointestinal side effects, and the prescriber decides whether to increase, hold or slow the progression. What this means practically is that a patient in month one is on a lower-dose pen than a patient in month five. If you are trying to understand how much semaglutide to take for weight loss, the dose is not yours to choose, which is exactly why that question belongs in a consultation, not a product listing.

For a fuller look at the dosing schedule itself, our prescribers explain it in detail on the page covering how much semaglutide to take.

Why private pricing varies, and what a headline price usually leaves out

UK private semaglutide (Wegovy) prices are quoted per pen, and pens correspond to dose strengths, so a lower-dose starter pen and a 2.4mg maintenance pen are rarely the same price. Since Eli Lilly's well-reported August 2025 list-price change for Mounjaro, market-wide attention to GLP-1 pricing has intensified, and some providers have restructured their Wegovy pricing similarly. If you are researching the cheapest site for Wegovy, reported private prices have ranged broadly by dose and provider, and our Wegovy price page gives more context on current market ranges.

What a headline monthly figure often excludes is worth checking carefully: consultation fees, prescription charges and dispensing fees are sometimes added at checkout. Delivery, which may seem trivial, can reach £10–£15 per order with some providers. Dose-review support (the clinical check before your prescriber issues a higher-dose prescription) is sometimes listed as a separate fee. If you're comparing quotes, the honest test is the total cost of a complete month's treatment, not the pen price alone.

There is also the question of genuine supply chain. The MHRA's Drug Safety Update communications have repeatedly flagged counterfeit weight-loss pens circulating online. Prices far below market, sellers without a verifiable GPhC registration, or promotions offering these medicines without a clinical assessment are meaningful red flags, not bargains.

How nume prices semaglutide treatment (and one honest thing we say upfront

At nume, one price covers the consultation, the prescription, the treatment, and free next-working-day delivery via DPD) tracked, in a plain unbranded box, nothing announcing what's inside. There are no add-on fees and no subscription. Every repeat order goes back to a GPhC-registered prescriber for clinical review; the price of that review is not billed separately.

We are not the cheapest provider. That is a deliberate choice. A GPhC-registered online pharmacy with same-day clinical review, ID and live weight verification, and seven-day aftercare costs more to run than an automated sign-up form. The current treatment pricing is shown on our treatment page; we don't print per-pen prices in articles because the right price for you depends on which dose your prescriber determines is appropriate.

You can verify nume, sorry, you can verify nume on the GPhC register under premises number 9012878. That check takes about thirty seconds and is the single most useful thing to do before handing over a prescription to any online pharmacy.

The right question to ask about semaglutide cost

Price is not the wrong thing to think about. It is the wrong thing to optimise for. A prescription medicine dispensed after a genuine clinical assessment, from an MHRA-regulated pharmacy stocked through the licensed UK supply chain, is not the same product as an identical-looking pen bought from a social media seller at half the price. The MHRA has seized large quantities of fake weight-loss pens since its first major counterfeit warning in 2023, some contained insulin rather than semaglutide.

The useful questions are: does this provider check that I am clinically suitable? Does a named prescriber review my information? Can I verify the pharmacy on the GPhC register? Is the supply chain traceable? Cost matters when you're comparing providers who all answer yes to those questions. It is a secondary consideration, not the lead one.
