## 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.
