❓ Common Questions

Frequently Asked
Questions

Retatrutide is a triple-action agonist that targets three receptors (GIP, GLP-1, and Glucagon), while GLP-1 targets only GLP-1 and GLP-2 targets GLP-1 and GIP. The addition of the glucagon receptor may explain the enhanced weight loss (28.7% vs 17% for sema******, 22.5% for tirzepatide) and the remarkable 86% liver fat reduction observed in trials.
