The thing I like most is the aftercare. I get really helpful emails with tips and advice. After week one I’m 6lb down, so let’s see where it takes me on my weight loss journey.

Products are very effective. I’ve lost weight already in just 14 days so happy. Would recommend this company highly. In fact I’ve already introduced 3 people to MedExpress.

I am one week into treatment and feeling good — less cravings and fuller for longer in between meals. The website is really informative and ordering a straightforward process.

I'm already on Mounjaro. Can I switch to Wegovy?

Yes, switching medications is common practice by medical professionals. Our goal is to find the safest, most effective option for your needs.

  • Wegovy is highly effective

    Clinical studies show people using Wegovy lose around 19% of their body weight on average over 72 weeks

  • You won't need to start over

    Most people do not need to start over. Our clinicians will review your experience with Mounjaro, including how effective it was and how well you tolerated it before recommending the most appropriate Wegovy dose to continue your treatment without interruption.

  • More benefits to consider

    Wegovy can cost up to £100.00 less per pen. It's also the first GLP-1 licensed for heart health benefits, is suitable for use with oral contraception, and tends to have fewer injection site reactions.

New to injectable weight loss treatment?

Here's an idea of what to expect over the first year of taking Wegovy.

  • 0-3 months
    From your first few doses, you may notice subtle changes in your appetite. As your dose increases, you#ll feel less hungry and see some weight loss.
  • 4-6 months
    You'll continue to build on your progress and healthier habits. You could see weight loss of around 11% of your body weight after 6 months.
  • 7-12+ months
    You'll be well into your journey and likely enjoying sustained weight loss, improved health, and increased confidence.
