Mazdutide vs Retatrutide
Which should you choose? Here's what you need to know.
The short answer
Both are next-gen dual/triple agonists showing dramatic weight loss. Retatrutide hits three receptors and has the highest weight loss data. Mazdutide is a dual agonist already approved in China.
Mazdutide
Weight Loss (GLP-1)Mazdutide is a GLP-1/glucagon dual agonist developed by Innovent Biologics. It beat semaglutide in a head-to-head trial and is already approved in China. Phase 2 trials in the US are underway.
Choose Mazdutide if:
You want a dual agonist that's already approved somewhere and has head-to-head data showing superiority over semaglutide.
Retatrutide
Weight Loss (GLP-1)Retatrutide is Eli Lilly's triple agonist (GLP-1/GIP/glucagon) with 28.7% mean weight loss in Phase 3 — the highest ever recorded. It adds a GIP receptor on top of mazdutide's dual mechanism.
Choose Retatrutide if:
You want the most aggressive weight loss possible from a triple-receptor mechanism, and you're comfortable with a still-unapproved compound.
