About
About Tesamorelin
Tesamorelin is an FDA-approved GHRH analog indicated for HIV-associated lipodystrophy and is used off-label in optimization medicine for visceral fat reduction and cognitive enhancement. Clinical data shows significant reductions in visceral adipose tissue and emerging evidence suggests neuroprotective benefits in older adults. It produces stronger and more sustained GH elevation than sermorelin. Compounded versions are available through licensed pharmacies.
Science
