Ben_jammin, no problem, glad to see you can also write correctly. It is a puzzler to me how one could be perfectly able to not capitalize the first word of words that shouldn't be -- and it's certainly easier typing not to -- when operating in given contexts, but do so when they shouldn't be in other contexts, but to each his own.
It's certainly not important on the forum, and would only be important in the actual paper. Please forgive me for thinking it possible that someone who would go to the erroneous trouble of the extra capitalization in casual writing might also do so in a paper.
As for serious contribution, I would go to:
and do a word search. There is at least one paper (as I have read it) that is a serious scientific study attempting to determine exactly what you are asking. They were looking at fairly modest doses of androgens and found about nothing, and specifically did not find statistically significant evidence of "roid rage."
That paper, at least, and perhaps there are more, should I think be included in any survey research of this topic.
If limited for whatever peculiar reason of the educational method employed to things people say on the Internet, my observation is that there is a great deal of individual variability.
With regards to the claimed effect that has the most public attention drawn to it, namely increased aggression or irritability, it seems to me that this is common when the dose is high enough. Which often is quite high. Even in these instances the effect is simply greater degree of impulse, not any uncontrollable "they can't help themselves" phenomenon overcoming the will and judgment. People still do what they decide to do, just perhaps have more impulse in one direction or another.
Individuals who are already prone to wrongful behavior when angry may find themselves in that situation more often. The problem is with the individual, not the androgenic steroid.
Other psychological side effects include that a limited number of particular anabolic steroids can cause depression, e.g. nandrolone, and it is not unusual for individuals to find positive psychological side effects from anabolic steroid use such as improved mood, energy, feelings of well-being, libido, confidence, and what might be called "positive aggression."
By positive aggression I mean a "can do," "I can go and get it done," "let's go for it" (when that is the right thing to do) feeling, as opposed to being more passive when passiveness or partial passiveness is not actually the best thing.
There may be another and better term for it. As you are studying the psychological field you probably have one: if a better term seems correct to you then amending my statement with the better term would probably be an improvement.
