Age is not the issue...........Intelligence is............I know a few +30 year olds that shouldn't be anywhere near AAS, for they are absolutely IGNORANT on the topic.....and then, there are a few sub 18 year old on this board that are nicely informed........just ask yourself, do I know the importance of diet, rest, fuel, and training? OK, do I know about the side effects, cycle lengths and history? AND most importantly, do I have proper knowledge of PCT and confidence to talk with my doctor at any given moment?
