Hey im 18, 6'3" 195lbs. and about 11% bodyfat. Im not too happy with where my stregth is and have always seen myself as being too skinny. I need to know if adding protein shakes to your diet is essential. I've been takin about 40 g a day off and on for the past 2 years. i doubt that has helped a whole lot. If i keep workin hard and start takin about 200 g a day will it increase my strength and help me to bulk up? thanks for any advice!
