i beg to disagree... if what you want is the classic "ecstacy" feeling you want to get some good MDMA. the only way to guarentee this is to test before you buy. this may sound like a hassle but look at it this way.
your first big roll will be your very best roll ever. no contest. the first time your brain gets some mdma in it you feel like god himself has blown you. everytime after that will not be as good. it will still be damn good, i'm not denying that, but e tolerance creeps in afetr the very first one.
its a whole lot like your virginity. you can give it away to any pill that crosses your path but if you do a bit of homework you might end up with a pill tats good in the sack, metaphorically and literally speaking.
also if you get your d.d. used to idea of testing the first time, it will become a standard and you will be guarented to always get good pills.
i'm going on about this coz so many people do what that ultra guy said and score some mitzi knockoff full of speed and buzz all night thinking they are on e when it so very far from the truth.
all i wish for you is that your first roll is as good as mine (1994, kelly splits, 140mg of MDMA) and if you buy a test kit and do some home work it can be.
good luck!!
