Tesamorelin (20 mg Vial)

Tesamorelin is a synthetic 44-amino-acid peptide analog of Growth Hormone-Releasing Hormone (GHRH). It stimulates endogenous growth hormone release and raises IGF-1 levels, leading to enhanced lipolysis and metabolic benefits. Tesamorelin is FDA-approved for reducing visceral adipose tissue in HIV-associated lipodystrophy and is studied for metabolic disorders and aging research.

Dose
1–2 mg per injection
Frequency
Once daily
Timing
Morning, fasted
