TestKitPlus MDMA (Ecstacy) Test Kit "Marquis" Reagent "Up to 200 Tests" Large Size Bottle Set
Use this kit to test for the presence of Ecstasy (MDMA, MDA, MDE), Speed (amphetamine) and other substances.
Our Ecstasy Test Kit includes what is also known as the “Marquis reagent”. It was the first test kit available and should be your primary test for Ecstasy (a.k.a. “Molly”).
Besides testing for Ecstasy and Speed, this kit will detect a range of other substances. A chart showing color reactions, as well as a multi-use testing vial, are also included with the kit.

Results may vary depending on sample impurities, adulterants, and other factors.
MDMA (Ecstasy) Test Tips
MDMA and MDMA-like substances (MDA, MDE) will turn from purple to black quite quickly – usually in less than 10 seconds. To differentiate between MDMA, MDA, and MDE, use the Folin test.
DXM (used in cough suppressants) turns from gray to black relatively gradually. Therefore, if you don’t see dark purple or black during the first few seconds of the reaction, what you have might not be MDMA.
Speed (amphetamine) turns from a reddish orange to a dark reddish brown.
If your sample contains both Speed and MDMA, both substances will react at the same time, yielding possibly a reddish or muddy color.
The testing vial that comes with the kit helps prevent your skin from contacting the reagent while testing. Extra testing vials are also great for when you’re on the go. But, using a white ceramic plate can help you see the results more easily.
It’s always better to test with multiple test liquids, as a double check and to screen for substances that don’t react with this test. See the Mecke test kit and the Mandelin test kit. If you can afford it, we recommend the Essential Drug Test Kit (3-In-1 Bundle), or the Complete Drug Test Kit (5-in-1 Bundle).
Test Kit instructions
Put a small sample into the testing vial. Your sample should be about this size: (●)
Hold the testing vial above the open plastic jar, so that if a drop misses the vial, it will land in the jar.
Place 1-2 drops of the testing liquid from the dropper bottle onto the sample. DO NOT let the sample touch the bottle nozzle, or the reagent will get contaminated!
Watch the color change over 30-60 seconds. Some reactions occur quickly (MDMA takes only a couple of seconds to turn dark purple/black). Other reactions take a longer time (aspirin and sugar gradually change color over the course of a few minutes).
Compare the sample color with the color chart provided.
Tightly close the dropper bottle. If you’re using more than one testing fluid, make sure you only open one bottle at a time. If you accidentally switch caps, the testing liquid will get contaminated and ruined.
Thoroughly wash the testing vial after each use.
Substance Color Change Time → Reaction Rate
MDMA/MDA/MDE (Ecstasy) Purple to dark purple/black. MDMA will turn dark purple within a couple of seconds, then black or very dark purple shortly after. Some bubbling (fizzing) may occur towards the beginning of the reaction. Fast
(≈ 5 sec)
Amphetamine (Speed) Reddish orange to dark reddish brown. Fast
(≈ 5 sec)
DXM Gray to black, may release small amounts of smoke right away. Reaction starts after 10 sec. and takes longer than MDMA to turn black. Medium
(≈ 20 sec)
“Bath salts” (methylone, butylone, MDPV…) Turns yellow quickly. Fast
(≈ 5 sec)
Cocaine No reaction
Aspirin Gradually turns pink, then a light red color. A very slow reaction. Slow
(5 min. or more)
Sugar Gradually turns yellowish, then to a brown color. A very slow reaction. Slow
(5 min. or more)

While reagent testing is the best method for on-the-spot testing, it is never 100% conclusive. There are many variables that can impact what the reaction looks like. Lighting, impurities, and unwanted substances in your sample may all play a role.
No drug (whether legal or illegal) is completely safe, we recommend avoiding all recreational drug use.
