Cyclezealot,
According to the makers of Endurox, the window is
when maximum benefit is acheived. The efficacy goes
down as the window closes but it is never a situation
where it would be useless to take (well, maybe after
a 2mile jaunt around the neighborhood, but you
catch my drift).
BTW Accelerade say this on their web site:
Enzymes responsible for manufacture of muscle glycogen are maximally stimulated 0-2 hours after exercise. Therefore it is essential that a carbohydrate supplement be taken in this time frame to optimize recovery
That kinda blows my earlier statement but I remember
reading that in their product literature.
you can read more about it at
Accelerade
