In Vivo

Retatrutide (LY3437943) (s.c.; 47 g/kg; single) engages GCGR in vivo and can improve glucose tolerance in an ipGTT through either the GIP or GLP-1 receptors[1].
Retatrutide (s.c.; 10 mL/kg; cycle every 3 days; for 21 days) causes great body weight loss and increases energy expenditure through glucagon receptor activatio[1].
Retatrutide has safety and tolerability[1].
