Tirzepatide's dual receptor mechanism How tirzepatide works: Dual GIP/GLP-1 receptor agonist Single molecule, two pathways GIP (glucose-dependent insulinotropic polypeptide) + GLP-1 Weekly subcutaneous injection FDA approved for diabetes and obesity GIP pathway effects: Enhances insulin secretion Improves insulin sensitivity Promotes fat metabolism Reduces inflammation Works synergistically with GLP-1 GLP-1 pathway effects: Suppresses appetite (central brain effects) Slows gastric emptying (moderate) Increases satiety Reduces glucagon Improves glucose control Combined tirzepatide results: 15-22% average body weight loss (monotherapy) Superior to semaglutide (GLP-1 alone) Well-tolerated in trials Approved and available See our tirzepatide dosing guide , semaglutide vs tirzepatide , and peptides for weight loss at SeekPeptides
