The whole 'roid rage' thing has been shown to be the result of elevated estrogen levels (excess testosterone is converted to estrogen, which is why steroid users take an aromatase inhibitor).
I've spoken with researchers that actually administered testosterone to human subjects in experiments, and they found no effect: it doesn't seem to trigger aggression or violence, at least not in the short term. It probably is a bad idea to ascribe a range of complex behaviors to a single cause, and limit it to those behaviors as well.
This is why I think the drop in testosterone is such a problem for many men. Your brain does not optimize for success and SMV anymore.

but I have to say that these "where is the source" posts are tiring and more often than not just a lazy attempt to destroy an argument with zero effort.
Reviewing the literature is separate and distinct from entering into argumentation.
If that can be achieved through aggression - a person going to do just that, if that is achieved through team play and compassion, the person would do it instead.
As Robert Sapolsky said, it is sad that in our society aggessive behaviour is the one that leads to success.
Absolutely some people can do massive amounts of steroids and have no aggressive tendencies, but other people immediately have problems. Its rather notable in some circles, like masters sports where lots of men are on TRT
and who knows what subtle psychological effects are at play, decisions being swayed by your new hormone makeup. Would make for fascinating research delving deeper
