No offense but, you're not an advanced athlete performing at a high intensity level for multiple hours on end. You are not depleting glycogen levels enough to worry about specialized shakes and what not. The supplement companies have brainwashed you.
The only time I would even worry about a pwo shake is if you do not have time to chew a meal after you workout.
I slammed specialized pwo shakes for years. One day I gave them up and I notice absolutely no difference in recovery verses going home and eating lean protein and starchy carbs.

you're right. .. i take nothing at all.. just very little creatine on workout days.. thats it. no difference at all between me downing whey shakes all day and not. when i was powerlifting in HS no one took nothing either. we drank water out of the fountain.. thats it. if whey powders were the answer our coach (whom was extremely competitive and serious) would of bought us buckets of whey to mix in with water.
