In recent clinical studies when PS (Phosphatidylserine), the primary ingredient in Cort-Bloc, was administered to strength athletes, cortisol levels were reduced by an astounding 30%. Cortisol is a stress hormone that causes the body to cannibalize muscle, so by controlling cortisol you increase your body's capacity to build more muscle tissue. PS has also been shown to improve memory and focus.
