Well if your bulking, your going to need carbs and lots of them. I would shoot for a 2:1 ratio of carbs to protein. Meaning. if your taking in 50 grams of protein, you should at least be getting in 80-100 grams of carbs.
Now i have read numerous articles on whats ideal postworkout and alot of them conflict ideas(nothing new in the world of bodybuilding) from solid food to a shake or complex carbs to simple carbs.
One thing they all agree on is you need to have sufficient carb intake to stimulate growth, release insulin and start the recovery/rebuild phase.
Now personally, i like to have a liquid meal directly after a workout, because i feel fast absorption is best. My shake consists of whey iso (myoplex) w/ carbs coming from maltodextrin(allready in myoplex) and extra dextrose added in.
I follow this shake up w/ a solid food meal about 1 hour after consumption of the shake. That meal is usually steak/ rice or eggwhites(a few yolks)/oatmeal or cream of wheat.
Basically, i would try a few of the ideas suggested and see what works best for you. Like i said, some reports i have read talked about how speed of absorption wasnt as big a deal as long as sufficient amount of carbs were ingested. I still like to lean towards the whey/simple sugar drinks postworkout for a few reasons. First, they taste damn good and secondly, i cant tolerate solid food directly after a workout.
