What Is Tesamorelin?

Tesamorelin is a synthetic analog of human growth hormone-releasing hormone (GHRH) consisting of the full 44-amino acid GHRH sequence with a trans-3-hexenoic acid group added to the N-terminus for stability. It is the only GHRH analog to have achieved FDA approval — specifically for HIV-associated lipodystrophy (reduction of excess visceral abdominal fat in HIV-infected adults) — providing a well-characterized clinical safety and efficacy profile that makes it a valuable research reference compound.

Tesamorelin stimulates pituitary somatotrophs via the GHRH receptor to increase endogenous GH secretion in a pulsatile pattern. Unlike exogenous GH administration, this preserves the natural feedback regulation of the GH axis. The FDA-approved clinical indication specifically targets visceral adipose tissue reduction, reflecting the compound's documented specificity for visceral vs subcutaneous fat in research subjects.
