Welcome. Way to go! You are fortunate to find PB while you are young, since your body is geared up with lots of growth hormone which will enable you get incredible results. You sound like one smart young man. My son had similar difficulties, but he leaned up by getting off the sugar/carbs and moving more. Just remember it can take some time to undo lots of years of CW, and don't listen to the wonks who will tell you you are wrong. I hope we see more young people like you here on MDA before long.
This time, like all times, is a very good one, if we but know what to do with it. Ralph Waldo Emerson
