This is your first step. I know a lot of people say a lot of things about try this or that, but even for newb guys, and ESPECIALLY for women who want to play around w/ steroids, to do their research and just understand what they are getting into. Not the boyfriend/husband/so - the woman is the one who needs to understand the effects of steroids. But even before going there, we're talking about things other than steroid use in an environment of training/ dieting / cardio / recovery specifically for physical / strength results. Outside of that particular goal, it becomes a little dicey because all the things and the discipline around using steroids for "bodybuilding" are not part of the lifestyle & discussion. Also part of that discussion is scheduling the whole thing as a cycle, a phase, that has a distinct start and stop time, and usually some sort of recovery period that deals w/ the "dismount" from the cycle and managing the body's response to the steroid attenuating back down to 'not present".
Not to beat it all to death, but starting point for this discussion is really at the doctor to get things quantified before stepping in w/ self-medication for only a very select result from all the things that can result from steroid use.
