Retatrutide exhibits highest potency at the GIP receptor (8.9-fold greater than endogenous GIP), with moderate activation of the GLP-1 receptor (0.4-fold) and lower, yet functional, glucagon receptor activity (0.3-fold)
2 This effect may arise from mechanisms involving reduced ectopic fat accumulation and better cellular glucose uptake
