I've never taken any steroid that changes my mood or attitude, not in my opinion and I've never had my girl or a family member point it out. So this is going to be very person dependent. I'm sure most ppl will vote tren tho and I'm sure that is probably the highest risk for everyone. If anything I would say I'm more irritable or in a less great mood off gear or cruising on my trt, which is still me being in a pretty good mood. But on a cycle with any of the following...test, mast, eq, dbol, anadrol I find myself in a better mood, just feel awesome. On npp and dienolone I didn't notice a change until I added prami or caber, but that just makes me compulsive, excessive gambling is usually the outcome lol.
I have seen my temper get shorter on cycles before but I'm talking about maybe giving someone less chances before I snap at them, example would be someone repeatedly doing something annoying or my kids not listening. And when I say snap I mean voicing my opinion faster or sending the kids to there room. I'm not going around slappin bitches and punching every person that pisses me off lol
