If I knew what I know now years ago, I would be much bigger...So much wasted time. My mistake was not eating enough total calories. For some reason I never put two and two together that I would need to eat more in order to put on more muscle, I always associated it with fat gain. I thought if I had enough protein the muscle gain would come with it. LCars, what mistakes did you make and what did you do to fix it?
