Retatrutide is a medicine for weight loss and weight maintenance that contains the active substance Retatrutide. It is similar to a natural hormone called glucagon-like peptide-1 (GLP-1) that is released from the intestine after a meal. Retatrutide works by acting on receptors in the brain that control your appetite, causing you to feel fuller and less hungry and experience less craving for food. This will help you eat less food and reduce your body weight. Retatrutide should be used with a reduced-calorie meal plan and increased physical activity.
