That is just plain stupid. Even without doing any research he had to realize that you cant just take things for that long(must have some money also to be supporting a cycle like that). If he was 110 lbs to start I highly doubt he has "the perfect body" now, but everyone has different ideals. Messing around with gear at such a young age and with such blatant disreguard for your health is asking for trouble. Do not admire a person like this...smart training, diet, supplementation and lifestyle changes will have you looking better than your friend in no time(and he will probably be in the hospital then if he keeps up his drug abuse).
*I am not trying to flame, and dont try and make some smart ass response to me...I am only trying to look out for you. Everyone makes mistakes and sometimes its hard to resist tempation when you start gaining the way he probably did(and I am sure people started noticing), but you have to also consider your future and what your really doing to yourself.
