The ehrlich reagent is the most popular test for LSD. It turns bright purple when an indole-containing compound, such as LSD is present.
It will not change colour when exposed to compounds from the NBOMe, DOx and mescaline families. 
To use, expose the test to a tiny piece of blotter paper or tab.
This DMT reagent test contains Ehrlich reagent, the most common testing kit for psychedelic compounds. Ehrlich test is best for DMT, LSD, and more.
The ehrlich reagent is used to test for the presence of indoles. The indole group is found in tryptamines and ergoloids like LSD, 4-AcO-DMT and ETH-LAD.
To use, cut off a small piece of blotter or use a scraping of pill or powder and drop the reagent onto it. A positive result will give a purple or pink reaction. NBOMes and DOx compounds may be sold on “fake” blotters and have much higher risks. These “fake” blotter compounds do not give a colour change with the ehrlich reagent. It is necessary to test with another reagent to be sure that these other compounds are not present in addition to something like LSD that would give a positive reaction with the ehrlich reagent. 
This bottle gives approximately 40 tests.
We sell the improved ehrlich reagent which uses phosphoric acid to extend the shelf life and improve result consistency as well as using amber glass bottles to prevent against reactions with plastic, light and moisture. This test should be stored in a fridge, where it will last around 24 months. If you can’t store reagents in the fridge then keep them in a cool, dark place.
Please note that this product is a matrix-bound test, not a liquid.
