Research overview

DoseGear research brief

Tesamorelin is an FDA-approved synthetic GHRH analog designed for HIV-associated lipodystrophy treatment. It provides selective visceral fat targeting with 15-20% visceral fat reduction in clinical trials while preserving subcutaneous fat.

Mechanism of action

Subcutaneous injection provides optimal bioavailability for GHRH receptor binding and pulsatile GH release stimulation, selectively targeting visceral adipose tissue while sparing subcutaneous fat.

Compound background

Development & research timeline

Study windows describe what researchers measured, not when an individual should expect a result.

Origin & development

Engineered GHRH analog developed as a medicine for excess abdominal fat in HIV-associated lipodystrophy.

What it is researched for

Visceral-adiposity, HIV-associated liver-fat, and selected cognitive research through endogenous GH and IGF-I stimulation.

Research observation window

Cited studies used 26 weeks, 20 weeks, or 12 months, depending on the indication.
