I keep saying it, it is a commercially manufactured product (besides the copies) for human consumption, it's was designed and made to be administered into the human body, BUT NOT at the doses BBers use, we're talking 10-20 times the recommended safe dose, this is where the risk is a serious concern.
I think you're right.
I guess the question is what is the "recommended safe dose". In terms of psychological effects the following might give us some idea -
“When given in the ordinary physiological range, or even up to six times the normal range, androgenic steroids have very few of the adverse psychiatric effects associated with anabolic steroid use,” says Harrison Pope, a Harvard neuropsychiatrist who has studied patterns of anabolic steroid use and their psychological effects.
"A 2004 British study by Daryl O’Connor and colleagues, published in The Journal of Clinical Endocrinology and Metabolism, found that healthy men treated with a relatively high dose of testosterone (1,000 mg/week) did not produce any detectable increase in aggressive behavior or changes in other nonaggressive or sexual behavior."

The article above is actually an anti-steroid article and also includes
For 10 years, Melloni and his collaborators have injected some 1,200 adolescent hamsters with anabolic steroids in amounts and combinations that resemble street doses, then carefully have tracked their behavior and neural responses.
“The results are very clear-cut,” he says. “If you give animals steroids, they are tremendously more aggressive.”
Bit confusing isn't it.
Anyone who uses anabolic steroids in 1k+ dosages I think would be pretty foolish anyway. Down regulation and binding sites limitations eventually make increasing dosage a waste for BB'ing. Of course AAS don't just affect muscle growth they also convert to nuero-steroids so you'd be stupid to overdose on them for no good reason, at least without taking a SSRI imo.
