Tesamorelin is a 44-amino-acid synthetic analogue of growth-hormone-releasing hormone (GHRH) with an additional N-terminal hexenoyl modification that extends its half-life relative to native GHRH. In research models it has been studied for its effects on pulsatile GH secretion, IGF-1 levels, and visceral adipose tissue composition.

Tesamorelin is used in GH/IGF-1 axis research, visceral-fat metabolism models, and preclinical studies of GHRH-receptor pharmacology.
