If your not sure of what your getting is Mdma I would advise not consuming,there is some sites out there where in most cases you could figure out if what your getting is in fact mdma.. I would suggest when you purchase your ex pill you take a look at pillreports.com most fake and real mdma pills will be most likely posted on there with some reports and sometimes test results.. Its very dangerous to take something your not sure whats substance might be in it, ive made the mistake of not researching my pills and paid the price with fake pills so make sure you have a good connect and research your pills and you should be cool..
