Protein factory. Go there, and make your own blend. The fat fast diet was revived in Testosterone webzine about a year ago by Brock Strasser. In the original article, he stated that he went through the protein factory and came up with his own whey/casein blend which is a good idea. When I'm on low/no carbs, I just love using Zero Carb Isopure, because it's virtually carb free and taste great. No aspartame, just sucralose which makes a world of difference. If you go to the protein factory and are concerned with taste, get the ion exchange whey isolate, the best tasting of all the proteins IMO.
