text: what is the best protein shake for bodybuilders that really works?and how many servings per day i should take?   optimum nutrition 100% whey is probably the most popular. besides just the protein, it has a bunch of other stuff like bcaas.  the taste is pretty good for a whey protein that is almost all protein (almost no sugar).  check out bodybuilding.com...they got a list of all the top whey proteins.  you should get about 1g of protein for every pound u weigh.  you shouldn't get all your protein from protein shakes tho.    1 serving of optimum nutrition whey has 24g of protein...so u do the math.
