The Liebermann Reagent tests for the presence of MDxx, DXM, bath salts, opiates, and 2C-Tx substances. Our kit contains enough reagent for around 200 individual tests.

Testing Instructions

Step 1 – Open Bottle

Remove the reagent bottle from the child proof safety container. The packing absorbent can be throw away. Carefully open the Liebermann Reagent’s factory sealed cap.

Step 2 – Load Substance

Using the provided mini tester spoon, place at least .010 to .005 Grams (Tiny amount) of the questionable substance into the empty testing vile.

Step 3 – Add Reagent

Add one or two drops of the Mecke Reagent into the testing vile.

Step 4 – Watch Reaction

Watch carefully during the re-action time, color changes, any fizzing or smoking.

Step 5 – Color Chart

Refer to the color reaction chart to determine if Heroin is present in the substance.

Storage and Handling


Wearing gloves, rinse testing vile and the mini tester spoon thoroughly with soap and water after testing. 


The Liebermann Reagent bottle cap should be closed tightly to ensure no leakage or unwanted exposure occurs.


It is very important to store away from light (UV Rays) and high temperatures. UV rays and heat will degrade the reagent and significantly reduce shelf life!


Reagent testing is never 100% definitive. There are many other factors determining reactions such as multiple substance mixtures. Having said that, our Marquis reagent is the first step toward determining the contents of what your identifying.
