There is no harm. There are slightly different ways to bodybuild, but I think if one does not have several years of experience bodybuilding and or has built a decent base and/or doesn't have the confidence to choose an approach, then they should hold off with the roids for some time, or forever. I don't have anything against roid use amongst responsible and personally accountable people (e.g., "clean up your own mess" and pay for your own healthcare if a problem arises), but remember: you play, you pay!
That's why I don't think roids should be taken by those who don't have the experience or insight to begin with.
Again, there's no harm; it's a pastime at the end of the day. It's not that serious. Lol.
