I am getting pretty sick of the protein powder I have been using. The powder I use is probably the cheapest whey I have ever seen, 6 lbs for $25 or $30. Am I correct in thinking "you get what you pay for" when it comes to protein. If so would say 40grams of isolate be as good as or effecting as the 66 grams i get from my cheap whey or should I still go with the 60ish grams regardless. reason I ask is becuase isolate cost a bit more then the stuff i use now.
