weird, it might be alot mental, not saying your crazy, but alot of guys when they take shit it gives them a sense of well being, bigtime, so it could be something like that, you might not be used to adrogens in your body(no matter how weak they are) and the caffine just would intesify it, you might just have a low tolerance, really low, but ive honestly have never heard of it happening, usually youd get pissed off and want to kill someone, on andro and caffine if your a new new new newbie, but everyones differnt i guess, just make sure like your not having bad sides or then you could possibly be alergic to something in it... gluck,
