Tesamorelin is a 44-amino-acid synthetic analogue of growth-hormone-releasing hormone (GHRH). A trans-3-hexenoic acid moiety extends its stability, prolonging interaction with the pituitary GHRH receptor and supporting endogenous GH release.
FDA-approved as Egrifta™ for HIV-associated lipodystrophy, Tesamorelin has been characterized in research for selective visceral-fat reduction while preserving lean mass.
