Tesamorelin (TH9507) is a stabilised analog of human Growth Hormone-Releasing Hormone (GHRH(1-44)). A hexenoyl modification on Tyr-1 confers resistance to dipeptidyl peptidase-4 (DPP-4) degradation, extending its in-vivo half-life relative to native GHRH. It has been extensively investigated for its capacity to stimulate endogenous, pulsatile growth hormone secretion and for downstream effects on visceral adipose tissue, lipid metabolism, and cognitive markers in adult populations.
Key research areas
Studied for its ability to amplify endogenous, pulsatile GH release without disrupting feedback regulation.
Clinical research has documented reductions in visceral adipose tissue in HIV-associated lipodystrophy models.
Investigated for effects on triglycerides, HDL, and non-HDL cholesterol in metabolic disease research.
Preliminary research explores effects on executive function and cognitive markers in older adults.
