The sports world has a plethora of products including  pills,  potions
            
 and tonics that provide loads of promises to give the athlete  that  winning
            
 edge.  Their  promises  include  improved  performance,  better   endurance,
            
 increased strength and better recovery. These can be  achieved  by  reducing
