you will pay alot more for a whey isolate only protein with no carbs. but if u get a isolate/concentrate mix u get only about 5g of carbs for a lot less, and if you are trying tp gain muscle mass the extra carbs wont hurt
…and a less quickly absorbing protein. Absorbtion rate is an essential factor when buying any protein, especially one you are considering for PWO purposes.

Is it? Or is that all marketing? I have taken every protein from generic whey concentrate to microfiltered, ultrafiltered, hydrolyzed, blah blah and never noticed any difference except in my wallet.
