Ya its just different than it used to be, I'd say the products I can get now are more pure than before you just have to know what to look for and how to look for it. As zombie said, test kits are a must now. They always were important but with the research chemicals
only getting easier and easier to obtain, you really need to have one now and do your research.
Also you can't expect to get good product at shows/clubs/festivals like it used to be. The only time I even think about getting product at an event like that is if its more underground/smaller, going to these mega festivals or big name shows and trying to pick up product is asking for trouble. Went to a big festival over the summer that had absolutely NO good product, you could tell too cuz everyone there didn't have that "vibe," I felt like I was the only one dancing, which is sad when your amongst thousands of people. But this recent very small event I went to, almost everybody there was really into the EDM scene and had good product. You could tell too cuz the place was just flowing with that vibe that MDMA
seems to give off. (Of course still test anything you get.)
It also really depends on the area. My area is really well set on getting good product (which I thank god for and never expect anything good to last forever) but I have traveled to other parts of my country and seen some pretty dismal MDMA scenes.
What I suggest to people if they want to have good MDMA when they want it for specific events, is to grab it when your sure its good and sit on it til then. I always do this because usually the real quality product only comes around a handful of times each year, then you grab as much as you can and hold onto it for the right moment. (I suggest this with alot of harder-to-get drugs
.) But this can be difficult for some.
