Frequently Asked Questions
What is Retatrutide?
Retatrutide is currently in Phase 3 clinical trials and has not yet received regulatory approval for commercial prescribing in the UK. Regulatory review is expected in the coming years. Register your interest with us and we'll notify you as soon as it becomes available through our pharmacy.
How does it compare to other treatments?
Mounjaro (tirzepatide) is a dual agonist targeting GLP-1 and GIP, producing up to 22.5% weight loss. Retatrutide adds glucagon receptor activation on top of this — creating a triple-action effect that achieves up to 29% weight loss in clinical trials, making it the most potent injectable weight loss treatment studied to date.
When will this be available?
Retatrutide is currently in Phase 3 clinical trials and has not yet received regulatory approval for commercial prescribing in the UK. Regulatory review is expected in the coming years. Register your interest with us and we'll notify you as soon as it becomes available through our pharmacy.
How do I inject Retatrutide?
Retatrutide comes as a pre-filled pen that you inject once weekly under the skin of your stomach, thigh, or upper arm. The needle is very fine and most people find it comfortable. We provide full video guidance and clinical support to help you feel confident from day one.
Who is Retatrutide suitable for?
Retatrutide may be suitable for adults with a BMI of 30 or above, or 27 and above with weight-related health conditions. It may be particularly appropriate for those who have not achieved their goals with other GLP-1 medications. Our prescribers assess your full medical history during the online consultation.
Are there side effects with Retatrutide?
As with all GLP-1 based medications, the most common side effects include nausea, vomiting, diarrhoea, and constipation — particularly during dose titration. These typically improve as your body adjusts. Our clinical team will support you through any side effects throughout your treatment.
