What is Retatrutide?
Retatrutide is a new weight loss injection that’s currently being tested and showing very promising results. It’s made by the same company that created Mounjaro, and it works by copying three natural hormones your body already makes to help control hunger, how much you eat, and how your body uses energy.

How effective is it?
In a recent study, people using Retatrutide lost up to 24% of their body weight in 11 months, the highest result ever seen from a weight loss medication.

Are there other health benefits?
Yes. People taking Retatrutide in the study also had better:
-
Blood sugar control
-
Blood pressure levels
When will it be available?
Right now, Retatrutide is still being tested in large clinical trials. These are needed to check that it’s safe and works well. If everything goes to plan, it might be approved around 2026–2027.
For now, it’s not available to the public, only people in research studies can access it.
