I'd like to try it, but I'm not clear on the protein drink mix-thingy. Do you mean soy protein isolate powder? The drink mixes contain all kinds of stuff, including sugars, flavorings... The soy isolate pure protein powder is pure soy isolate. Also, the directions are not clear. It states 50/50 for soy and gluten; yet has 3 ingredients -- the drink, the soy flour, and the gluten. Will you clarify the measurements please. Thanks, it sounds good.
