The actual relationship of testosterone levels – natural or supplemented – on aggression is quite a bit murkier than, and perhaps even the opposite of, common folklore. See for example: http://www.nature.com/scitable/blog/cognoculture/testosterone_and_human_aggression_or_180520 http://www.nature.com/scitable/blog/cognoculture/testosteron...
