This heroin purity test is a quick test for heroin that will give you an idea about its purity. With this test you are able to find out whether and how much the heroin has been cut. Use it after you’ve tested your sample with the Opiates (Mecke) test, which gives an indication of whether or not Heroin is present in the first place.

Dealers cut heroin to increase their profit margins. The substances used for cutting are sometimes harmless, but sometimes dangerous substances are added. As a general guideline you can say that when there is a high percentage of heroin present in the sample, you are close to the top source and the cut of dangerous adulterants are diminished. This test does not tell you anything about the adulterants that were used to cut the sample with.

Please use only 20 mg (a tiny amount) of your sample. If you use too much, the results will be skewed! When comparing different samples, test using the same quantity from each. You can use the materials that come with the kit to help you get the right amount. However, for best results, use a scale to weigh the exact amount of powder. You can buy a good portable digital scale from here:

Test samples from different sources at the same time, so that you can more easily compare results. Take pictures of the test results under the same lighting and with the same camera. Use the pictures to compare with results from future tests.
