Couple questions... For a guy who just gets finished lifting weights what is your best carb source to ingest with protein?

I swear to god one week I read a slow acting carb then the next week I read you need a fast acting carb to get into the bloodstream quicker. Gives me a headache.

By the way where is this preworkout powder at already!?!?! I still have your work number don't make me give you a call tomorrow.
