Roid rage is probably a myth. The causation likely goes the other way. Meaning aggressive people are more likely to use steroids than steroids are causing them to be aggressive:
While I disagree with your claim that steroids are a viable form of birth control, I do agree a bit with this, though not for the stated reason.
What many people don’t realize (probably in large part because they see testosterone and estrogen as diametrically opposed things) is that testosterone levels impacts estrogen levels. Why? Because the body produces estrogen through the aromitization of testosterone. Increasing testosterone will increase estrogen.
A common struggle for those on TRT (both those at true replacement levels, as well as those taking supraphysiological doses) is elevated estrogen. I know that when my estrogen levels have gone too high, I become more neurotic than I usually am.
If you couple increased neuroticism with an elevated sense of dominance (especially at bodybuilding doses), and top that off with a general lack of poor management of one’s emotions (which I suspect is common amongst bodybuilders), what you likely get is a very volatile person. Not because of testosterone, but because of the elevated estrogen and their existing psychological issues.
