What Is Reta ?
Retatrutide is an peptide drug that promotes weight loss by simultaneously activating three hormone receptors: GLP-1, GIP, and glucagon. GLP-1 receptor activation reduces appetite and slows digestion, leading to lower food intake, while GIP helps regulate glucose and may support fat metabolism. Glucagon receptor activation increases energy expenditure by stimulating fat burning. Together, these mechanisms create a caloric deficit, resulting in significant body weight reduction.
