Dual Ketamine Test Kit comes with 2 single-use reagents for ketamine as well as its common adulterants. It is used to positively identify ketamine, DCK, 2-Oxo-PCE, MXE, MXP and to rule out  2C-B, DOx, NBOMe, NBOH, PMA/PMMA, and different, less predictable and less desirable, highly toxic dangerous drugs. Multiple reagents are required to detect adulterants and increase analysis precision.

The Dual Ketamine Test Kit instructions and apps feature over 500 substances. Each single-use vial contains 0,2 ml (4 drops) of a reagent. Glass protects reagents from light, plastic, and moisture to ensure prolonged shelf life. For extra-stealth ask us in the checkout notes to remove substance-related stickers and fliers.

SIN Dual Ketamine Test Kit consists of 2 reagents: Mecke and Mandelin (2 tests total). It’s best to use this set for ketamine and other dissociatives, but it’s also good for meth/amphetamines, cocaine 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: Dual Ketamine 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.

How can I test ketamine?

BEFORE using a ketamine test kit

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

STEP ONE for testing ketamine powder / crystals

  • Take and finely crush a small piece, no bigger than a head of a needle – like this •.
  • Carefully open a vial and using included spatula move the sample into the vial.
  • Wait for the results and check instructions.
  • Dispose of safely.

How to use a ketamine test kit?

  • Check test results starting with  Mecke test kit: if testing ketamine there should be no color change.
  • Check test results with Mandelin test kit: if testing ketamine there should be a orange to brown color change reaction.

AFTER using a ketamine test kit

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


  • Liquid. 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 ketamine test results:

MARQUIS No color change
MECKE No color change
MANDELIN Orange > Brown
FROEHDE No color change
EHRLICH No color change
HOFMANN No color change
SIMON’S No reaction
ROBADOPE No reaction
SCOTT No full color change

Ketamine test did not react as indicated? Watch out!
All test results are available in our instructions and TestDrugs apps.

How to check if reagent for testing ketamine works?

  • Test any substance and compare color reactions with instructions. It’s easiest to use vitamine C – Mandelin reagent reacts to it with a blue color change.
  • Keep a sample to compare later in case of doubt. If control sample reacts fine, it means the reagent still works.

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.
