The MDMA Purity Test enables you to quickly get an idea about the purity of a sample, in other words: how much of this sample is really MDMA or Molly. With an accurate scale, a little time and your phone you can then calculate how much MDMA is in a sample. This is the only test currently available that can do this and it is relatively easy to do.
The heroin purity test enables you to quickly get an idea about the purity of the heroin. Just open the ampoule and add 20 milligrams (exactly!) of your sample to this test. The bottom layer will reveal a yellow/orangey color which becomes darker when there is more heroin present in the sample. You will have your result within seconds!
