For this summer I tried Isopure Whey. I got chocolate and it tasted pretty damn good, with milk and water. The thing that sucked though, is that it was impossible to mix. Being into chemistry, if you heat it, it will dissolve a ton easier... but thats if you want a hot chocolate protein shake. I'm heading back to school now I think I am going to get another jug of it. With less strenuous of a workout during school time 1 jug should last me a while.
Also after reading some more of your posts, it has about 25g protein per scoop. It's chocked full of essential amino acids, and all kinds of other goodies. I did a workout without having a shake afterwards... I was dead the next day. I love this stuff.
