my first cycle i didnt use an Aromatase inhibitor (AI) and was a little off the handle when it came to fights and was way too agressive. my more recent cycles that i have run with higher doses of gear have been giving me way less agression and been more mentally stable. I think that arimidex was the x factor there. it kind of makes sense because estrogen will make you strait crazy. just my 2 cents but it might be worth a try.
