How Much Semaglutide Should I Inject — and What Does a Private Prescription Actually Cost?

You've found a price online. Here's what that number may not cover

Picture this: you've searched, you've compared, and you've found a monthly figure that looks manageable. Then you go through checkout and discover a separate consultation fee, a prescription charge on top, and a delivery cost that nudges the total into a different bracket. It happens more often than it should. In the UK private market, the cost of semaglutide treatment varies between providers, and as widely reported in August 2025, Eli Lilly's list-price rise for tirzepatide pushed the sector to revisit its pricing structures more broadly. For Wegovy specifically, typical private monthly costs range roughly from £149 to £375 depending on the dose and the provider, and if you are currently on or moving to the third maintenance step, our Wegovy 2.7 mg price page gives a clear breakdown of what that dose costs through our pharmacy. Those figures are what patients pay at checkout, which is not always what they see in the headline.

What headline prices often exclude: the initial clinical consultation (sometimes £30–£75 separately), a prescription fee, the cost of ongoing dose reviews, and delivery. A quoted price for the pen alone says nothing about what happens if you have a question at 9pm on a Saturday. Understanding that gap is the first practical step before committing to any service. You can read more about how Wegovy pricing works in the UK on our Wegovy price page.

The dose question, and why the answer has to come from your prescriber

There is a common misconception worth letting go of gently: that there is a standard dose of semaglutide for weight loss that most people settle on, and that you can simply ask for that amount from the start. In reality, the licensed schedule for Wegovy (semaglutide 2.4 mg, and now up to 7.2 mg following MHRA approval in April 2026) begins at 0.25 mg weekly for the first four weeks, moving through 0.5 mg, 1.0 mg, and 1.7 mg before reaching the 2.4 mg maintenance dose, with each step confirmed by a prescriber based on how well tolerated the previous dose was. The MHRA-approved Patient Information Leaflet, not an online guide, is the definitive reference for your specific pen and schedule.

Starting lower than you might expect is not a shortcoming of the treatment. The gradual increase is there to let your body adjust, reducing the chance of the nausea and gastrointestinal effects that tend to be most pronounced in early weeks. A prescriber who skips that assessment and simply ships you a higher-strength pen without clinical review is not saving you time, they are removing a safeguard. If you are wondering how much semaglutide you should start with and why the opening dose is set where it is, our dedicated page walks through the reasoning behind those early weeks. Our guide to how much semaglutide you should take explains this in more detail, including how individual factors influence where you land on the schedule, and the weight-loss dosing overview covers how the maintenance phase works once you are established on treatment. For a broader look at what Wegovy involves, the Wegovy treatment page is a good starting point. The NHS medicines page for semaglutide sets out the licensed dosing framework clearly if you want the official patient-level reference.

What a single transparent price should actually include

At nume, we are not the cheapest provider and we entered the market knowing that. A single price covers the consultation, the prescription, the treatment, and next-working-day tracked delivery to your door, no additions at checkout, no subscription that rolls over without you noticing. Every repeat order is reviewed by a real clinician before it is approved and dispatched; that review is not an automated tick-box. The current treatment pricing is shown on the weight-loss treatments page, and the consultation itself is free.

That choice reflects something straightforward: for a prescription medicine, the cheapest listing answers the wrong question. The question that matters is whether the supply chain is licensed, whether a qualified prescriber is genuinely reviewing your case, and whether someone medically qualified is reachable if something changes. Our about us page sets out how our pharmacy is structured and regulated, including our GPhC registration number, which you can verify directly on the GPhC register. You can also read about our clinical oversight approach on the clinical team page.

Safety is the right metric (especially when the market includes unverified sellers

The MHRA has warned publicly about counterfeit weight-loss pens sold via social media and unofficial online channels, with large seizures of fake pens in 2024 and 2025) some containing insulin rather than semaglutide. The pattern that precedes those purchases is usually familiar: a price well below what the licensed market charges, a seller who does not ask for a prescription, and no verifiable GPhC registration. If you see a discount code offered for a prescription medicine from a seller you cannot verify, that is a flag worth taking seriously. Suspect sellers can be reported at the MHRA's Yellow Card scheme.

Verifying any online pharmacy takes less than a minute: the GPhC register lets you search by name or registration number. For questions about what to expect from treatment or how our process works, the FAQs and contact page are there. If you have questions about the practical side of administering your injection, our page on how much to inject with semaglutide walks through what the process looks like week to week. And if you want to understand the weight-loss results people typically see on semaglutide before deciding, the expected weight-loss guide draws directly from the published clinical-trial evidence.
