May improve cognitive functionHow It Works
Tesamorelin is a synthetic analogue of growth hormone-releasing hormone (GHRH) with a trans-3-hexenoic acid modification that improves stability. It stimulates the pituitary to release growth hormone naturally while preserving physiological feedback. FDA-approved as Egrifta for HIV-associated lipodystrophy, it specifically reduces visceral adipose tissue.
