Pharmacological Profile & Mechanism of Action
What it is: Retatrutide (LY3437943) is an advanced next-generation synthetic 39-amino-acid peptide that acts as a triple receptor agonist—activating GLP-1, GIP, and Glucagon receptors at the same time.
How it works: In addition to the appetite suppression and insulin optimization of GLP-1 and GIP, Retatrutide's glucagon receptor activation directly stimulates the liver and brown adipose tissue to burn calories, actively ramping up resting energy expenditure. This means the body burns more fat even while resting, rather than merely relying on caloric restriction.
Why researchers study it: Researched as the most potent weight loss and metabolic compound discovered to date, achieving over 24% mean weight loss in trials, complete resolution of fatty liver disease, and profound improvements in blood lipids.
