How to test MEPHEDRONE?

How to test mephedrone: if you intend to use mephedrone, first you need a mephedrone test kit to check it for adulterants. Pure mephedrone usually looks white, but can’t be identified by appearence. To test mephedrone use reagent tests Marquis, Mecke, Liebermann, Froehde and Zimmermann in a multiple-use test kit. To detect all ingredients and estimate potency it’s required to use an additional purity test kitsTo detect fentanyl or test for fentanyl analogs it’s recommended to use fentanyl test strips.


Reagents presumptively indicate PRESENCE, but not PURITY or QUANTITY. Use different reagent tests to improve accuracy and to detect adulterants – 90% of adulterants will react with 1 out of 3 tests, and 95% with 1 out of 5. To detect all ingredients and estimate potency it’s required to use an additional purity test kit
A positive or negative test result does not indicate if the substance is safe. No substance is 100% safe.

What test kit do I need to test mephedrone (4-MMC)?

SAMPLE RECOMMENDED MEPHEDRONE TEST KIT
4-MMC /
a-PVP /
Hexen /
other cathinones

How can I test mephedrone (4-MMC)?

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). *If using single-use vials insert the sample and observe, as the reagent is already within.
  • Add one (or two) drops of Marquis reagent test (or other supplied) on the sample and wait for the results.
  • Check reagent test results with 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).

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).

Next choose a purity testing kit. It enables you to detect all sample ingredients at once, however still requires reagent tests to identify substances.

  • To estimate amphetamine purity (number of ingredients and their concentration) use the Substance Purity Test Kit.
  • To precisly estimate MDMA purity use the MDMA Purity Test Kit, which in addition includes a calibrated plastic ruler.

AFTER using a mephedrone test kit

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

FAQ

  • Liquids. If your substance is not dry, evaporate the solvent before testing with reagents.
  • Fizzing. Any 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).

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 color change.
  • Keep a sample to compare later in case of doubt. If control sample reacts fine, it means the reagent still works.

How can I detect fentanyl?

BEFORE USING A FENTANYL TEST STRIP

  • It’s RECOMMENDED to test each and every dose. Because of extreme potency (microgram range) fentanyl is never evenly mixed in.

STEP ONE FOR TESTING FENTANYL POWDER / PILLS / SPICE

  • Dissolve 100-200 mg in at least 125 ml of water (half a cup).
  • Grab a test strip by blue end and insert it into the liquid, no higher than the blue line.
  • Wait until liquid starts visibly moving up the test strip (up to 15 seconds).
  • Put the test strip away on a flat dry surface and read the result in 2 minutes.

HOW TO USE A FENTANYL TEST STRIP?

  • Check test strip results: a single line confirms the presence of fentanyl, while two lines (even faint) rule it out.

Next choose a purity testing kit. It enables you to detect all sample ingredients at once, however still requires reagent tests to identify substances.

FAQ

  • Faint line. Even faint second line result is enough to rule out the presence of fentanyl.
  • Injecting. If you inject you especially need to test each and every dose. It’s best to test the spoon (or cooker) residue every time before use.
  • 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 single fentanyl test strip is enough for one test.
