The Science
Triple-Agonist Technology
Retatrutide simultaneously activates three metabolic receptor pathways: GLP-1, GIP, and glucagon. This creates compounding effects that single or dual-agonist peptides cannot match.
GLP-1 Receptor
Appetite Suppression
Reduces hunger signals and increases satiety after meals.
GIP Receptor
Fat Metabolism
Enhances insulin response and promotes fat breakdown.
Glucagon Receptor
Energy Expenditure
Increases thermogenesis and caloric burn at rest.
