I think it's predominantly a myth that has a legitimate basis in reality. Tren, anadrol, even halo and cheque drops will not suddenly turn a normal, self-controlled man into a raving raging monster, so in that respect it's a myth. I know, I've run almost all of them and I've never become violent in the slightest. However, those strong androgens certainly DO increase your aggression and increase your sensitivity to otherwise mildly annoying stimuli. So, in that respect, they can certainly make it easier to lose control. You just have to be smart and mature about it, realize that what you're feeling isn't a rational response, and be a little more patient. Perhaps it's tougher for some than for others, but I've always held the belief that steroids won't turn a nice man into a madman, but they WILL turn an a**hole into a much bigger a**hole!
