My roomate swears by this stuff... never mind the fact that he's almost 200 pounds (marshmallow fluff) and can barely do 20 pushups without a almost having a stroke. He normally gets the strawberries 'n creme, but one time he decided to try the alpine punch. He found the flavor to be too nasty so he gave the tub to me.
At first I was like "Score! This stuff is expensive as hell. Must be awesome."
Overall, not that much more impressive than most protiens. Sure, one serving has 50 grams of protien, but wait, a single serving is two scoops, so it doesn't have any more protein than your standard whey (you're body can only use about 20g at a time anyways, from what I am told). If you're trying to lose weight, I suppose the zero carbs thing works out alright, but if you're trying to gain it, like myself, you need carbs.
Flavor was weird and unsettling, texture was chalky. Despite claims, stayed chunky despite mixing it for several minutes in a shaker cup.
Overall, not a terrible product, but excessive for a supplement of it type, in my opinion. Whey protein, the staple of supplements, is pretty simple by nature. Seeing as how supplements are so expensive to begin with, this is one of the few categories you can really skimp on. Most of us use it simply to add more dietary protein. The differences between this and your basic $10 jug of Wal-Mart designer protein are for the most part superficial.
Then again, I'm not a registered dietitian, so maybe the fat that it's purer/dissovles clear/no carb/makes your teeth whiter/comes with chrome spinners/forged in the fires of Mt. Doom makes it superior in some way, but I have yet to tell.
