While you are correct - I have seen some folks who became very dangerous under steroids - minds were not right and were on hair triggers for violent rage attacks - with lots of extra rage strength due to unnatural muscle mass/tone.
I’m sorry, but I’ve been around steroid users for the better part of 30 years. This is a myth. What I have seen, though, is people who have a much higher confidence level due to their size and srength and will be more aggressive than they otherwise would have been. It’s a psychological, not physical side effect.
