I'm only 19 is that too young or is that like borderline? I read some people say they started at 19 and others advise against it. At this age i have a lot of natural testosterone, if i was to use AAS would my testosterone be the same as it was before when i stop using it, after i do PCT of course? I've been reading up a lot on it for about a year. and i'm not considering doing it yet i want to train hard and eat hard for about 3 more months then maybe try it out i'm not sure yet. so what do you guys think am I too young should i wait a few years or do you think it would be ok? i'm just trying to make a smart decision but i want to get big i'm a naturally skinny person and i eat a lot i just can't seen to get much bigger.
