What GLP-1 is
GLP-1 is an incretin hormone released from the gut. Agonists at this receptor are the single agonist end of a family that runs through the dual agonists such as tirzepatide to the triple agonists such as retatrutide. Receptor coverage is the axis that separates them.

Common questions
How does this differ from tirzepatide and retatrutide?
Receptor coverage. This acts at GLP-1 alone. Tirzepatide adds GIP. Retatrutide adds GIP and glucagon.
