I use nothing else but Designer Protein.

100% whey protein - the best. Mixer - ice, protein powder (liquid sweetnlow) a little water - whip it up, lots of protein - low in fat (that's just my own style) and yum. Very pricey from GNC, but I get it much cheaper off the web. http://www.planetdepot.com/ProductB...nufacturerId=13

It makes a mouse if you whip it up for a long time. So gooooood. Carbolite, Carb solutions and all the rest are just okay, but contain other ingredients I don't want/soy protein, maltodextrin, wheat gluten, caseine...designer protein also has TONS of vitamins and minerals in it...great stuff. Mix it up with eggs and you CAN make muffins/pancakes out of it...no kidding.
