For the OP - that is some great progress! Keep working out hard, and you will see how in a year or two you will drastically grow in size. I have also been in your place - was skinny no matter how much I trained till I turned 19 - then oh my god - I was growing like hell!
For the other haters - it is pityful to be that picky with someone's words, when the topic of the thread is completely different. Besides, it is silly to tell someone that he is worse than this zyzz, because he is dead, and his physique is useless if you are dead. The OP is alive, and he will surely be alive, since he seems to be quite smarter here. Learn to respect the others.
