How Much Weight Can You Lose on 1mg Wegovy?

Why your weight loss at 1mg is real, but incomplete

The dose schedule for Wegovy runs from 0.25mg to a standard maintenance dose of 2.4mg, with steps at 0.5mg, 1mg and 1.7mg along the way. Each step lasts around four weeks, so 1mg is typically where you are in weeks nine to twelve of treatment. By that point, appetite suppression is building and most people have already lost some weight, but the clinical trial evidence that makes headlines refers to what happens over 68 weeks at the 2.4mg maintenance dose.

In STEP 1, published in the New England Journal of Medicine, adults on semaglutide 2.4mg lost an average of around 15% of body weight over 68 weeks alongside lifestyle changes. At the 1mg mark you are still months away from that outcome. Some people feel the dose working clearly at this stage; others notice modest changes and find things accelerate once their prescriber moves them up. Both are normal, and neither is a signal to stop.

The 2.4mg maintenance dose is where the trial results were recorded, and the 1.7mg step sits just before it. Understanding where 1mg sits on that path matters before you make any decisions about whether treatment is delivering what you hoped.

What private Wegovy costs in the UK, and what often gets left out of the headline figure

Private treatment with Wegovy is priced per four-week pen, and that price shifts as doses increase. Since Eli Lilly raised its Mounjaro list price in September 2025, the UK private market for GLP-1 weight-loss medicines has been re-pricing broadly; for context, private semaglutide costs typically range somewhere in the region of £149 to £375 per month depending on the dose and the provider, though those figures move and vary, treat them as indicative rather than fixed. The current Wegovy pricing picture is worth reading if cost is the central question for you.

What matters is what that number actually includes. Headline prices sometimes cover the pen alone. Separately, you may find consultation fees, prescription charges, delivery costs and follow-up reviews sitting outside the figure quoted upfront. That adds up, particularly on a medicine that requires clinical review before each new pen is issued. A question worth asking any provider: is every repeat order re-reviewed by a prescriber, or is it automated once you're set up?

If you are based in Scotland, private Wegovy pricing in Scotland broadly follows the same market, though NHS access routes differ between nations.

What the one price at nume actually covers

We are not the cheapest option. That is a choice, not an oversight. The single price at nume covers the clinical consultation, the prescription, the medicine itself, and free next-working-day delivery, your pen arrives in a plain, unbranded DPD box with a tracking link sent to your phone, and the KwikPen inside is refrigerated during transit. There are no subscription commitments. Every repeat is re-reviewed by a GPhC-registered Independent Prescriber before it is issued; a real clinician reads your update, not software.

Our pharmacy holds GPhC premises registration 9012878, which you can verify on the GPhC register directly. Medicines come through the licensed UK supply chain, with Novo Nordisk as the manufacturer. Aftercare is available seven days a week. There are no discount codes, no promotional pricing and no vouchers, not because we forgot, but because running them on a prescription medicine would be the wrong thing to do. What we focus on instead is the service around it.

Why cost-per-pen is the wrong question for a prescription medicine

For a prescription-only medicine, the cheapest listing answers the wrong question. The MHRA has warned publicly about fake weight-loss pens circulating through social media and unverified sellers, in 2025, around 20 million doses of illegally traded weight-loss medicines worth approximately £45m were seized, and the first UK site manufacturing counterfeit tirzepatide pens was raided. Semaglutide pens are among the most counterfeited medicines in the UK right now. A seller offering them at a noticeably low price with no visible clinical process attached is a red flag worth taking seriously.

The right question is whether the provider is GPhC-registered, whether the medicines come from the licensed supply chain, and whether a qualified prescriber is making decisions about your care. If you want to check any online pharmacy yourself, the GPhC register is the place to do it. Suspect sellers can be reported via the MHRA's Yellow Card scheme.
