What do you think the ratio of men to women is who get into fist-fights, etc.? Of course much more men, due to higher T-levels. It is the same with animals, like lions and elephants, etc., the males fight like crazy when breeding season hits and their t-levels are elevated. If you castrate a healthy adult male, his behaviour will change dramatically, less aggressive towards other males, and almost no sexual drive towards anything!
That is one reason why I don't want to mess with steroids, I am 28 years old, already a very aggressive and horny person, the last thing I need is more test, even if it helped my muscles grow, it effects alot more than just muscles.
I am not saying that if you take steroids you will turn into a raving lunatic, just that steroids (basically all hormones) absolutely affect the nervous system and that can translate into behavioural changes.
edit- BTW, I am not anti-steroids, there are valid reasons to use them, just as there are valid reasons not to use them.</div>
theres a big difference between dominant behavior and plain old aggressive tendancies,if it was the case that everyone with high levels of test became agressive then there'd be alot more murders,when you consider that most serious people on gear are running between 500mg-4 grams per week,which is well over 10x the norm.however im willing to accept that behavioral changes do occur,of course.test is only part of the equation when talking about behavior changes,dht,seratonin and other chemicals play a vital roll in these changes,it comes down to,each person is effected differently.
