Tesamorelin

What is Tesamorelin?

Tesamorelin is a synthetic analogue of human growth hormone-releasing hormone with a trans-3-hexenoyl group added to its N-terminus, a modification that increases resistance to enzymatic breakdown while preserving activity at the GHRH receptor. It is the active ingredient in an approved medicine, used clinically for a specific indication.

How it is understood to work

It binds pituitary GHRH receptors to stimulate pulsatile growth-hormone secretion, which drives a downstream rise in IGF-1. Because it works through the body’s own GHRH axis rather than bypassing it, normal feedback regulation of GH release is preserved, distinguishing this mechanism from direct administration of growth hormone itself.

Research status

Tesamorelin has been studied extensively in human clinical trials for its effects on visceral adipose tissue, hepatic fat, lipid profiles and body composition, giving it a stronger clinical evidence base than most peptides in this catalogue. It is also used in broader preclinical research into GH-axis function and age-related metabolic change.
