As others stated, ON Gold Standard is at the top of the heap for quality/cost. I also use Dymatize ISO100 Hydrolyzed Isolate. Just a tad more expensive but it has less calories, less fat and less carbs with a slightly higher and better protein profile. Both are top choices and I purchase my supps at bodybuilding.com however GNC has good sales at times.
