How much semaglutide should you take — and what does it actually cost?

The biggest myth: that you can just choose your dose like a product variant

A lot of people arrive at this question having already decided which dose they want. That's understandable. You've read about the 2.4 mg maintenance dose, perhaps seen the 7.2 mg pen mentioned in the news, and you want to know what it costs. Here's the thing the framing quietly gets wrong: semaglutide dosing isn't a product choice you make. It's a clinical decision your prescriber makes with you, titrating upward from the 0.25 mg starting dose as your body adjusts, and staying there if that's what's appropriate.

The starting dose question is actually distinct from the maintenance dose question, and conflating them leads to unrealistic expectations on both counts. You won't begin on 2.4 mg. Most people spend several months stepping through lower doses before reaching it. That affects cost calculations too, because early treatment months typically involve lower-dose pens that may carry different prices. A prescriber who has reviewed your full health picture decides the pace. At nume, that review happens the same day you submit your consultation, a real clinician reads your answers, not an automated system.

So: the dose question and the cost question are linked. If you want a detailed guide on how much semaglutide to take at each stage of treatment, that page walks through the titration schedule in full. Both are part of a single, properly supervised process.

How UK private semaglutide pricing actually works

Private semaglutide treatment in the UK is priced per pen per month, and the range across providers is wide. Since Eli Lilly raised Mounjaro's list price in September 2025, comparable pressure has landed across the GLP-1 market, and as widely reported, private prices for injectable weight-loss medicines at the higher doses can now run from roughly £149 to over £300 per month depending on which medicine, which dose and which provider you're using. These figures are market context, not fixed benchmarks: prices shift, and your actual dose may differ from the highest.

For a fuller picture of what Wegovy-specific treatment costs across the dose ladder, the Wegovy price breakdown page covers the ranges in more detail. Patients often ask how much Wegovy they should be taking, and that page also helps clarify how the dose ladder maps to the pens you'll actually be prescribed. One provider quoting £10 less per pen may add those items back individually; the total ends up higher.

According to NICE's recommendation for semaglutide (TA875), NHS access is available only through specialist weight management services, subject to strict eligibility criteria. Private treatment exists for people who don't meet those criteria or don't want to wait. Understanding what you're actually paying for is the sensible starting point.

What the single price at nume covers

We are not the cheapest option for semaglutide treatment. That's a deliberate call. The single price you see covers the clinical consultation, the prescription, the medicine, delivery and ongoing aftercare, nothing added later. The consultation is reviewed the same day by a GPhC-registered Independent Prescriber, and if treatment is clinically appropriate, your order is dispatched the same day (order by 12pm, Monday to Friday) and arrives the next working day via tracked DPD in plain packaging.

There is no subscription. Every repeat order is reviewed clinically before it goes out. If you want to know more about how the service is structured, the about page covers it, and you can verify our pharmacy on the GPhC register directly at premises registration 9012878. Our clinical team leads that oversight.

Specific treatment pricing is shown on the treatment page, we don't list per-pen prices in body copy, and the reason for that sits in the next section.

Why the cheapest semaglutide listing is answering the wrong question

Semaglutide is a prescription-only medicine. The MHRA has been explicit: these are not suitable for quick or cosmetic weight loss, and they should only be used under clinical supervision. The MHRA has also warned publicly (and continues to warn) about counterfeit and illegally sold weight-loss pens reaching UK patients through social media and unverified online sellers. Some of those fakes have caused serious harm. Sellers offering semaglutide without a prescription, with suspiciously low prices or via discount codes, are a clinical red flag, not a bargain.

For anyone researching the cost of semaglutide alternatives or wondering whether cheaper options are legitimate, the short answer is that legitimate supply means a licensed UK pharmacy, a real prescriber, and medicine sourced through the authorised supply chain. A common question alongside cost is how much semaglutide to inject at each dose step, and understanding that helps clarify why clinical oversight matters throughout. The right metric for a prescription medicine isn't the lowest price, it's whether the clinical process protecting you is actually in place.

If you're trying to work out whether you're likely to be suitable, realistic expectations around results are worth understanding before you start. Questions about the consultation or ongoing support are answered on the FAQs page. When you're ready to take the next step, the consultation is free.
