Understanding RETA
What is RETA?
RETA, short for retatrutide, is a triple receptor agonist that acts across three metabolic hormone pathways: GLP-1, GIP and glucagon receptors.
How does it work?
RETA works across three different hormone receptor pathways, each with a different role in appetite, glucose and energy regulation.
01
GLP-1
GLP-1 receptor activity is associated with appetite regulation, insulin secretion and the slowing of gastric emptying.
02
GIP
GIP is an incretin hormone involved in the body's insulin response and the regulation of energy metabolism.
03
Glucagon
Glucagon receptor activity plays a role in glucose regulation and energy expenditure.
