How It Works
Retatrutide is the first triple agonist — activating GLP-1, GIP, and glucagon receptors simultaneously. The glucagon receptor activation is the differentiator: it increases daily energy expenditure by stimulating hepatic fat oxidation and thermogenesis. This three-pronged approach addresses appetite, insulin sensitivity, and metabolic rate in a single molecule.
Key Research Areas
Triple Mechanism
Broadest receptor pathway activation — 3 mechanisms at once
Energy Expenditure
Enhances daily caloric burn via glucagon activation
Visceral Fat
Preferentially targets deep abdominal adipose tissue
Lean Mass
Preserves muscle during aggressive fat reduction
