Overview

Description

Tesamorelin is a stabilized analog of growth-hormone-releasing hormone (GHRH 1–44). The added trans-3-hexenoic acid group makes it more resistant to breakdown than native GHRH.

Mechanism

It binds GHRH receptors on the pituitary and prompts pulsatile growth-hormone release in the body's natural rhythm. Its effect on visceral adipose tissue, and how durable that effect was, have been examined in clinical research (Dhillon, 2011; Spooner et al., 2012).
