Weight Loss & Metabolism
Semaglutide is a GLP-1 receptor agonist peptide that has become one of the most widely studied weight loss compounds in recent years. It mimics the natural hormone GLP-1 by binding to GLP-1 receptors in the pancreas, gut, and brain. In the brain, it reduces appetite and food cravings by acting on hypothalamic neurons that control hunger and satiety. In the gut, it slows gastric emptying, which prolongs the feeling of fullness after eating.
