Good mentions here. I liked Anator p70 from muscletech, its discontinued, but you can find essentially the same thing in Dark Matter, Torent, Myozene, the new Size on. Its a basic creatine, high leucine, bcaa, hydolyzed whey, and high carb pwo drink. Its basic but works very well. Obviously you can make your own. Replace the hydrolyzed whey or add MAP for an even faster absorbing protein, ibcaa's, creapure, leucine, and some simple sugars. Heck throw in some glutamine for digestion and whatever else you feel like.
Progenex worked extremely well for me too, and its low carb.
