Absolutely not. That only means they spend more money on advertising. I could make protein out of my basement, and theoretically, if I were to advertise alot for it, then you and people like you would buy it. Does that make it a quality protein? No.
Eas and Muscletech do make quality products. It is just that their prices are so much more than is needed, it is retarded. Base your decisions off your own results and the results of others. NEVER on the amount of advertising they do!!!
