Until those questions are resolved, any comparison that ranks retatrutide above tirzepatide on the basis of a larger phase 2 number is comparing an early signal against an established body of evidence an apples-to-oranges contrast that the eventual head-to-head or fully published phase 3 data will replace
Unlike semaglutide (Ozempic/Wegovy), which activates a single receptor (GLP-1), or tirzepatide (Mounjaro/Zepbound), which activates two (GLP-1 + GIP), retatrutide activates three metabolic receptors at once: GLP-1 slows gastric emptying, suppresses appetite, improves insulin response GIP additional insulin-sensitivity and appetite effects Glucagon boosts energy expenditure and lipolysis (this is the new mechanism) The glucagon component is what makes retatrutide unique
Because these drugs slow digestion, some experts caution that pill absorption may be reduced, though large-scale studies are still lacking
