1. Retatrutide’s primary mechanism involves potent activation of the GIP receptor, which plays a vital role in appetite regulation by directly affecting the brain’s satiety centers. This reduces hunger, cravings, and overall food intake.
2. Through GLP-1 receptor activation, retatrutide supports glycemic regulation and enhances satiety. GLP-1 also slows down gastrointestinal motility and delays gastric emptying, leading to increased feelings of fullness after meals.
3. Activation of the GCG receptor by retatrutide is believed to increase energy expenditure and promote fat oxidation, largely through metabolic actions in the liver. GCG receptor stimulation encourages fat breakdown and elevates metabolic rates. Additionally, it induces “beiging” of white fat, converting it into beige fat with thermogenic properties similar to brown fat, thereby boosting calorie burning and enhancing metabolism.

Effect:

• Weight loss
• Helps lower blood sugar
• Slows gastric emptying
• Improved metabolism
• Muscle building
