IguanaI liked it, but my GI tract hated it, if you get my drift.
Not sure if you're talking about the powder or their zero-carb pre-mixed drinks. Both are supposed to be "lactose free." It's not unusual for me to drink two of the zero-carb drinks daily, but I have to drink them far apart or I get gastrointestinal chaos. (I assume the "toilet paper" Tommy mentioned is the whey coagulating; shake it and it disappears.)
I think that even if the lactose is removed or if you aren't lactose-intolerant, an ultra-high infusion of protein will cause GI distress, anyway.
I have a client who is a nutritionist and she argues that it doesn't matter how clean of lactose a whey product is. She says most people who are lactose-intolerant still have an allergic reaction, even if less severe, anyway.
Once again, I urge y'all to check out proteinfactory.com. You will save a ton of money on the highest-quality stuff you can buy and you get to design the flavor and sweetener and pick any additions you want.
