kickedinjunk and *Supernova*: It is highly recommended by the people who use this site (and I guess I'd have to suggest that by saying this it is the opinion of bluelight) that using a tester is imperative and that you should test each pill you have before taking it. Relying on a dealer to give you good pills is not really good enough. The good MDMA 'imports' that they are getting may not actually all be the same pill (this was seen with the TP's earlier this year, but luckily they were only a MDMA, MDA mix {pls correct me if my memory has failed me}) and even your dealer may not be aware of this. Testers are available online and I imagine if you searched hard enough around any capital city you should be able to find somewhere that sells them.
Any info we can gain about what we are consuming can hopefully increase our chances of staying happy and healthy (i.e. not dead).
