At the ripe young age of 19 I have come to the realization that I am quite the weakling. Im 6"1 and 150 pounds, I've seen sixth grade girls who could beat the living hell outta me. Anyway, I've got quite a thin frame and was looking to change that. Would it be possible for someone with a decent knowledge of HGH to tell me whether im to young or not to be doing this, and not how can I properly supplement myself while taking the hormone. While im on the subject, is there SOMETHING i can take at this stage in my development to simply get larger bones, and to all around be bigger?
