Well generally, most guys that do use are doing it to get big young. It's simple fact of it. They want to enjoy gains now and make best use of them in their prime age not when they're 30.
I've heard of plenty who do and don't regret it in the slightest. Zyzz is a name which pops up and many will know (Google him, used when he was 17), don't think he is. I don't personally see it as an issue. Aslong as you A) know what to do B) implement it properly with good diet and training and arn't stupid on it.
But I definitely agree good workout knowledge etc does come with a bit of time working out for couple months and then using gear is stupid because you'll have no idea what you are doing. But as far as advocating people reach their natural first I can't say that'll be for everyone as most want it now. Whatever gets job done quicker for people aslong as they do it smart and whatever you say will not persuade them otherwise. If someone is dead set on jumping onto their first cycle they'll do it whether you or I or anyone tells them not too.
So I'm just saying if you're gonna do it, at least do it right. Regardless of whether you're at your natural potential or not, your gains on cycle will be nowhere near comparable to doing it natural. Indeed probably main reason people do use and if they do it right the benefits are there for the taking.
