FAQ

What makes Tesamorelin different from natural GHRH?
Tesamorelin shares GHRH's 44-amino-acid sequence but adds a hexenoyl group at one terminus, increasing resistance to enzymatic degradation and improving stability compared with the unmodified natural peptide.
What is Tesamorelin's FDA approval and WADA classification?
It has one FDA approval: reducing excess visceral fat in HIV-associated lipodystrophy (brand: Egrifta). WADA lists it as prohibited at all times under S2—growth-hormone-releasing factors subclass.
Why is Tesamorelin shipped as lyophilized powder?
Freeze-drying removes water to maximize shelf stability and minimize degradation during storage and transit. The powder is reconstituted with bacteriostatic water immediately before laboratory use.
