That stuff is rather expensive if I remember correctly...
But like Snagency said there isn't really a "best" protein ever. Isolates are great post workout but as a meal replacement a blend would be a much better option.
Are you looking for pure isolate protein? Or just a good option?
I recently had a tub of OxyElite chocolate protein and I liked it quite a bit. Right now though I'm using Phase8...MuscleTech hype or not I got eight five lb jugs for twenty bucks each and its not bad either. Myofusion, Syntha6, Truetein all of those are ok.
