Medical disclaimer

Everything on this site is for general education. It is not medical advice, and it is not a substitute for talking to a doctor or pharmacist who knows you.

What this site is, and is not

We summarise published research, regulatory decisions and public-health alerts about retatrutide in plain English. We try hard to be accurate and to cite everything, but we are a website, not a clinic. Reading our pages does not create any relationship between you and us as clinician and patient, and we cannot know your medical history, your other medicines or your circumstances.

Nothing here should be taken as a recommendation to obtain, prepare or use any product. Retatrutide is an investigational medicine. It has no licence in the UK or anywhere else, and the MHRA has said that products sold in the UK claiming to contain it are likely to be illegal and potentially dangerous.^[1] The trial results we describe come from a pharmaceutical-grade product given under medical supervision; they do not describe anything you can obtain today.

Please talk to a real person

If you are thinking about weight loss, your GP or a pharmacist can tell you what is available to you, including licensed medicines and NHS weight-management services. If you have already used a product sold as retatrutide, please tell your GP, even if you feel fine. They will not judge you, and possession is not an offence. The page on talking to your GP may help.

If you are unwell

• Emergency: call 999 or go to A&E if someone is collapsed, struggling to breathe, confused, has severe tummy pain, or has yellowing of the skin or eyes.
• Urgent but not an emergency: call NHS 111 or use 111 online.
• Not urgent: contact your GP.

The page on when to seek help lists the specific warning signs.

Report a reaction

If you think a product has harmed you, report it to the MHRA's Yellow Card scheme.^[2] You can report unlicensed and counterfeit products, not only medicines from a pharmacy, and your report helps the MHRA spot patterns and act. How to report a reaction explains what to include.

Our limits

We check every page at least every 90 days and update it when the evidence changes, but medicine moves fast and a page can be out of date on the day you read it. We are not responsible for decisions made on the basis of anything here. The terms of use say the same thing in more formal language, and the editorial policy explains how we work.
