Liebermann reagent is one of the primary tests for cocaine, ketamine, mephedrone and many new psychoactive substances. It can help rule out Levamisole or other highly toxic compounds. Liebermann Reagent Test Kit comes with instructions and apps for over 500 substances. Every bottle contains 5 or 10 ml, with each 1 drop accounting for 1 use, 100-200 total. Brown amber glass protects reagents from light, plastic, and moisture to ensure prolonged shelf life. Special high-quality HDPE dropper guarantees 0 spills.

The Liebermann reagent is a mixture of sulphuric acid and potassium nitrite. On its own it is colorless. It’s best to use Liebermann reagent to test cocaine, ketamine, or mephedrone, however, it’s also a good test for benzofurans, MDMA and MDA, meth/amphetamine, opioids, tryptamines, and phenethylamines.

NOTE: Liebermann reagent deteriorates with time, especially if exposed to sunlight or not refrigerated. If you are uncertain whether the reagent will work, test it with a previously checked sample.


NOTE: Liebermann can only test the PRESENCE, not PURITY or QUANTITY of a specific substance.
Always test under a strong light and using the smallest possible sample. Never open more than 1 bottle at once, if you make a mistake you might contaminate the reagents and spoil them. If a few reactions are happening at once, only the darkest one of them will be visible. To detect adulterants, try using on fresh samples secondary reagent tests like Robadope, Simon’s, Scott or Zimmermann. If you don’t know yet how to test using Liebermann reagent, see the following instructions:

  1. On a clean ceramic surface (e.g. bottom of a mug or a plate) prepare a sample no bigger than this size -> ●
  2. Carefully not to touch the sample with the bottle, remove the cap, twist the bottle upside-down and wait for 1 drop to fall. Replace the cap.
  3. Immediately observe the color change and compare it with the Liebermann color chart. No reaction within the first 30 seconds or unexpected results indicate the sample doesn’t contain the expected substance or is adulterated.
  4. Neutralize the reaction with baking soda (optional) and flush in a sink under running water for a few minutes.

No reaction can be caused by MPHP, etizolam, cocaine, caffeine and many other substances (or lack of active ingredient).

Common Liebermann color reactions:

  • Cocaine – yellow (needs Scott test)
  • Ketamine – yellow
  • MDMA / MDA – immediate violet or brown to black (needs tests Simon’s and/or Robadope)
  • x-MMC / a-PVP / Hexen and more cathinones – yellow (needs tests Zimmermann and/or Simon’s)
  • bk-EBDP / Butylone – yellow to brown (needs tests Zimmermann and/or Simon’s)
  • MDPV – yellow to green (needs tests Zimmermann and/or Simon’s)
  • M/ethylone – yellow to black (needs tests Zimmermann and/or Simon’s)
  • Pentylone – brown (needs tests Zimmermann and/or Simon’s)


Liebermann reagent consists mostly of concentrated acid and is strong enough to burn skin and clothing. Keep out of eyes and mouth. Keep away from children. Always use in a well-ventilated area. Wear gloves (supplied) when handling the bottle and cap. Wear protective eyewear. Never point towards face etc. If you get some on you/clothing, then immediately wash with soap and water. Wash testing surfaces with soap and water as well. Dispose of any unwanted reagent down the sink with running water and baking soda (supplied), ventilate. Store all testing kits away from any heat in a cool, dark place between uses. The average shelf life of 1 year can be significantly extended by storing in a freezer (warm to room temperature before use).

A positive or negative reaction for a substance does not indicate if it is safe. No substance is 100% safe.
