Heroin Purity EZ-Test – 10 Pack
The Heroin Purity Test enables you to quickly get an idea about the purity of the heroin. Just open the ampoule and add (EXACTLY!) 20 milligrams of your sample to this test. The bottom layer will reveal a yellow/orange color which becomes darker when there is more heroin present in the sample. You will have your result within seconds.
By far, the most advanced test on the market for people who want to know what they are dealing with.
This Heroin EZ-Test contains 10 testers.
