How does Retatrutide compare to Tirzepatide and Semaglutide?

Retatrutide is a triple agonist acting on GLP-1, GIP and glucagon receptors, whereas Semaglutide targets GLP-1 alone and Tirzepatide targets GLP-1 and GIP. In research settings the triple-receptor profile is studied in energy-expenditure and substrate-oxidation models.
