By purchasing SIN Mephedrone Test Kit you support our fight for drug policy based on harm reduction, human rights, and facts, not prejudice.



Mephedrone Test Kit comes with 5 reagents for cathinones like mephedrone and common adulterants. It is used to positively identify mephedrone and to rule out a-PVP, MDPV, bk-EBDP, NEP, and different, less predictable and less desirable, highly toxic dangerous drugs. Multiple reagents are required to detect adulterants and increase analysis precision.

The Mephedrone Test Kit instructions and apps feature over 550 substances. Every bottle contains 5 or 10 ml, with each 1 drop accounting for 1 use, 100-200 total. High-quality HDPE and brown amber glass bottles protect reagents from light and moisture to ensure prolonged shelf life. Special dropper guarantees 0 spills. For extra-stealth ask us in the checkout notes to remove substance-related stickers and fliers.

SIN Mephedrone Test Kit consists of 5 reagents: Marquis, Mecke, Liebermann, Froehde and Zimmermann. It’s best to use this set for mephedrone, MDPV, a-PVP or derivatives, but it’s also good for 2C-B, benzofurans, MDMA/MDA and opioids.

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

NOTE: Mephedrone Test Kit 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.

BEFORE using a mephedrone test kit

  • It’s RECOMMENDED to record the reaction to compare later

STEP ONE for testing mephedrone powder / crystals

  • Take and finely crush a small piece, no bigger than a head of a needle – like this •.
  • Put it on a suitable testing plate, preferably a spot test plate or the bottom/underside of a ceramic mug (example).
  • Add one (or two) drops of Zimmermann reagent test part A, followed by one (or two) drops of Zimmermann part B (or other supplied reagent) on the sample and wait for the results.
  • Check reagent test results in instructions.

How to use a mephedrone test kit?

  • Check test results with Zimmermann test kit: if testing mephedrone there should be a slow purple to brown color change, which confirms the presence of a secondary cathinone (like 4-MMC or methylone).
  • You can also use Simon’s test kit, which except for 4-MMC and derrivatives turns navy blue with any secondary amine like MDMA, meth or PMMA (cathinones change color slower than the rest).
Detecting synthetic cathinones using Zimmermann Reagent Test
How to test mephedrone? Testing mephedrone (4-MMC) using Zimmermann reagent shows gradula color change from purple to brown. This reagent is included in the Mephedrone Test Kit.

STEP TWO testing mephedrone for adulterants

  • Try reagents that that should NOT change color with mephedrone: MarquisMeckeFroehde or Robadope.
  • Use Robadope to confirm primary amines like 2C-x, amphetamine, MDA or PMA.
  • Use Simon’s to confirm secondary amines like methamphetamine, MDMA or PMMA (fast blue color change).

AFTER using the mephedrone test kit

  • OPTIONAL: Pour baking soda over a finished reaction to neutralize used reagents.
  • Wash testing surface under running water.


  • Liquids. If your substance is not dry, evaporate the solvent before testing with reagents.
  • Fizzing. Any synthetic drug in a form of salt will bubble with most reagent tests, which are strong acids. If you see only fizzing instead of color change, that can indicate presence of a new psychoactive substance.
  • Speed of the reaction does not indicate quantity nor purity. However, if you are having trouble interpreting your result try using a bigger sample or crushing it better before testing.
  • How many tests can you get from one test kit? A multiple-use test kit lasts up to 100 (5 ml) or 200 (10 ml) tests. Each drop equals one test. A single use-test kit contains 2 disposable ampoules (2 tests).

All mephedrone test results:

MARQUIS No color change
MECKE No color change
FROEHDE No color change
EHRLICH No color change
HOFMANN No color change
SIMON’S Slow blue
ROBADOPE No color change
SCOTT No full color change
ZIMMERMANN  Purple / Brown

All test results are available in our instructions and TestDrugs apps.

How to check if reagent for testing mephedrone works?

  • Test any substance and compare color reactions with instructions. It’s easiest to use aspirin – Marquis reagent reacts to it with a slow pink or orange color change.
  • Keep a sample to compare later in case of doubt. If control sample reacts fine, it means the reagent still works. Learn more in the general guides how to test drugs or how to detect cuts.

Reagents consist mostly of concentrated acid and are 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.
