I hope you are 100% serious about not using steroids because, aside from your age, you are FAR from ready. This isn't an insult, everyone had to start somewhere. We are all ignorant of the knowledge necessary to use steroids at some point. But, the reason I am stressing this is because you are asking this question, this shows that likely you ARE considering using steroids.
Ok next, practically speaking of course, it is hardly necessary to make a distinction between "AAS" and "pro-hormones"/"pro-steroids"/whatever else you want to call them. Sure, the mechanisms in which they work are slightly different, but practically speaking, they are all "steroids". The whole "AAS vs. PH vs. DS" thing is WAY oversold. For our purposes, they all belong in the same general category. Let the pharmacologists, those in related fields as well as the armchair impersonators put the various compounds in more specific categories.
They all have the potential to shut you down, they offer the same side effects, etc. Many would argue that what is available on the "legal" PH/DS market is LESS safe than the illegal stuff. This is because PH/DS are mostly compounds that were at one time abandoned by researchers for one reason or another, sometimes these reasons were because of their undesirable side effects. Anyway, that's another topic. My point is that prohormones/designer steroids are at LEAST as dangerous as the common illegal stuff, and can (in most cases WILL) cause HPTA suppression.
Oh, and by the way, temporarily not being able to "get your buddy up" is just a small consequence of uneducated steroid usage. In your case, you would be lucky if that's all that happened to you given your age.
