Sam's Journey

20kg weight loss

Sam says she reached a plateau during her previous weight-loss journey before making a change and continuing her progress.

“I hit a wall with Mounjaro where the weight loss stopped. It was costing me hundreds of pounds per month, so I made a change and I've now been able to continue my weight-loss journey. I feel and look like a new woman!”

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.

Triple receptor activity: GLP-1 + GIP + Glucagon
