What kinds of protein have you tried?

I ordered some from bariatriceating.com but havent recieved them yet. I did pick up about 5 samples from Whole Foods-not any tasted good-I still have 2 to try. The best thing I have found so far-was leftovers from a liquid diet I tried at the beginning of the year called Nutrimed. I am hoping to find more on Ebay. Its good & mixes up well. Very smooth. So far not much luck!!
