I use the Jay Robb's one or the Fat Flush one, I think they taste the best and they are the only ones I can find that are sweetzened with stevia only. I would like to get the "whey to go" but they don't know where to get it.
Jay Robb is the absolute best protein available in my opinion. It is all natural and it tastes great! Its is the only brand that i know of that can make stevia taste good. I would encourage everyone to stay away from anything with splenda aka sucralose in it. And of course avoiding asprtame should be a no brainer.
