There was what I'd consider a good article (not that I know anything about the subject) on steroids in the August/September issue of Planet Muscle written by Jeff Everson. He's been around for ages, used them and has a PHD so should know a thing or two. He outlines both the pro's and cons, and there are plenty of cons it seems especially if you do not know what you are doing. He says, that some bodybuilders have permanently damaged their hypothalamic-pituitary gonadal axis so that testosterone remains depressed even with HCG & other drugs.
He basically says that generally there is no real data (is anyone collecting??) that shows low doses of AAS over short time periods are dangerous, but you must be careful and monitor your Test, cholesterol, triglycerides, liver & muscle enzymes, etc closely, do BUN tests, prostate checks etc.
He also points out that the typical dosage these days is much higher than it used to be (maybe 10x, and that may be one reason for the bloated abdomens, [internal organs are overgrown] of today's competitors as opposed to those in Arnie's day). Most product available in gyms is highly suspect and are nothing like the real pharmacy grade original, dodgy additional ingredients aside, and many new variants of old favorites also have questionable results.
