I'd stay with the Met-rx original. You can make your own post workout shake for under a buck a serving. I got help putting it together on this site. 35 grams of whey(fast digesting), 85 grams of dextrose(simple carb, spikes insulin levels quick), 8 grams of creatine, 150mg of ALA(aids in replenishing muscle glycogen). The taste is extremely sweet, but I can deal with it. Its a pretty effective mix and tailored for post workout. You can get most of the stuff from this site. The dextrose from home brewery kit sellers.
