I think a lot of you don't understand what creatine does. creatine increases your ability to use energy in the muscles. it doesn't make you bigger, it doesn't make you stronger...it simply unlocks your natural potential by allowing you to utilize the stored energy more effectively.
you don't need a sugar transport (grape juice).
creatine also isn't 'instantly' used...so taking it immediately before working out doesn't mean you're gonna have a better workout.
In fact, AFTER your workout, the muscles inthe body are craving nutrients like protein, carbs (in the form of glycogen), as well as creatine and amino acids.
so if you add 5g of creatine to your post workout shake, you're golden.
