§ 01 Overview
Overview
FDA-approved GHRH analog that specifically reduces visceral adipose tissue (VAT), originally developed for HIV-associated lipodystrophy.
FDA-approved 2010 for HIV-associated lipodystrophy. Extensive Phase III data; off-label use for VAT reduction.
§ 02 Mechanism
Mechanism of action
Tesamorelin is a stabilized GHRH(1-44) analog. It stimulates endogenous GH release and preferentially reduces visceral fat, with favorable effects on IGF-1 and hepatic fat.
- 01Targeted visceral fat reduction (15–20% VAT decrease)
- 02Improved liver fat markers
- 03Lean mass preservation
