Last time i purchased mdma crystals was back in 2002/2003 so i cant remember its exact smell lol, but i do remember it did have a noticably chemical smell. Its appearence was either beige or a whitish grey colour, small very sparkly crystals. More sticky then meth crystals.
But sayimg that mdma can be a mulitude of colours but lighter the better. It should be a crystaline substance, if someone was selling mdma, they wouldnt allow it to
dry out and make the mdma look dodgy....
P.s while im on this topic, i recently was on pillreports i posted a comment that xtc tablets need to be stored correctly or they will not last, and how from personal experience i had stored some e's incorrectly in just a ziplock bag (was not kept in a dark, cool, dry place) and after acouple years when i went to consume them out of courisosity the pills easily crumbled and were def not as strong as previous. I was then told i had no idea what i was on about (headdah incl) with smart ass comments that mdma would last as long as the pyramids and pills last forever. Well i didnt feel the need to reply to the comments in there because the quality of pillreports has gone to the shit. But.... Yes mdma will last a long time if stored corrrectly, yeah 99 percent + pure mdma crystals, and the last time i checked xtc pills were def not pure mdma crystals pressed into a pill. The binders and other chemicals added and even the impurities in the mdma will start to absorb heat, moisture if not carefully stored. In pill form mdma (cos its obviously not just pure mdma crystals would have a shelf life all depending how well their kept away from heat, moisture and air)
