However, in keeping with our data on receptor pharmacology, increasing the dose to 30 nmol kg 1 , tenfold higher than maximal doses from our studies, shows that tirzepatide does have insulinotropic activity in Glp1r -/- mice or in the presence of a GLP-1R antagonist 5 , demonstrating that tirzepatide can engage the GIPR in mouse beta cells at sufficiently high concentrations
