i saw a topic about someone wanting to build muscle, and i am also curious about this, i train 2 to 4 times a week, it varies as i could be called into work for overtime etc, i drink very simple milkshakes, wack 2 eggs, milk and flavouring into the blender and drink, but i saw that people need to drink shakes with PCAA's or something like that i cant remember, if someone could just tell me what supliments i should be intaking, what they do, where i can get them and average cost,

thanks in advance
