How to test MEPHEDRONE?

To test MEPHEDRONE always use more than 1 test, because there are more substances than colors. Tests presumptively indicate PRESENCE, but not PURITY or QUANTITY. A positive or negative test result does not mean, that the substance is safe. No substance is 100% safe.


  1. Crush onto a clean surface (e.g. bottom of a mug) a sample no bigger than a pin head
    PILL – finely crush a small piece, about 1/20th
    LIQUID – Pour a drop on unbleached paper and dry before testing
  2. In good light pour 1 drop of a test onto your sample We recommend tests included in the Mephedrone Test Kit
    SUBSTANCE COLOR might slightly distort results
    A SAMPLE SIZE might react differently than smaller
  3. Compare the first 10-60 seconds of a reaction with flyers
    FLYERS are available at
    APPS available at for web browsers and Android devices can help interpret results
    RECOMMENDED – record reaction to compare later

Pour baking soda over a finished reaction. Your pipes (and environment) will thank you!

All reactions to test MEPHEDRONE

 MARQUIS No reaction
 MECKE No reaction

 ZIMMERMAN Violet > Brown

A test did (not) react as indicated? Watch out!

ZIMMERMAN reagent can distinguish secondary from tertiary synthetic cathinones. Most of the time secondary beta-ketones (4-MMC derivatives) react violet turning to brown, while tertiary (a-PVP derivatives) show immediate strong yellow color reaction, but there are exceptions, such as these:

Zimmerman Reagent

If you want to detect an admixture of PMA, 2C-x, Amphetamine, Nor-Mephedrone or other primary amine use Robadope and Simon’s. To detect all adulterants try a TLC Kit or laboratory analysis. If you have the slightest doubt, test fentanyls presence using Fentanyls SIN Test
