As with everything some people are more prone to aggression than others to a wide varying degree, one of my friends took 200mg deca for about 3 weeks to try to help his shoulder and could not control his rage, but he has always been a hot head and quite frankly a general asshole. He ended up in jail took out 7 cops on his way.
I am a very cool customer it takes ALOT to piss me off, so I get away with doing massive amounts and see no aggressive sides. Ok some mild aggression here and there but nothing noticeable sometimes I bitch more than normal.
As far as sex drive, I'm sure that varies somewhat from person to person as well, 2 cycles ago I was chasseing my girl all over her apartment trying to talk her into all kinds of kinky stuff every hour or so, then off cycle she was chasseing me and I was less interested. This cycle I'm currently on is on the high side but my sex drive is only mildly increased.
