Marquis Reagent Description

The Marquis reagent is a primary test for MDMA (Molly/Ecstasy), meth/amphetamines, synthetic cathinones (bath salts),”NBOMe” compounds as well as other substances.

Our Marquis reagent contains the same reagent chemicals as found in U.S. Justice Department reagents. A chart showing color reactions, as well as a multi-use testing vial, are also included with the kit.

To make it easier to find this product, we also list the Marquis reagent as an MDMA test kit on our site.

Test Kit Includes:

  • Bottle with testing fluid
  • Color chart with instructions
  • Multiple-use testing vial
  • Protective storage/transport jar

Marquis Reagent Color Reactions

Marquis Reagent Color Chart Image

A chart showing Marquis reagent color reactions with various substances.
While other substances may also produce color changes, we have found Marquis to change colors with:
25I-NBOMe, 2C-B, 2C-E, 2C-I, 3-MeO-PCE, 3-MeO-PCP, 5-APB, 5-MeO-DMT, 6-APB, amphetamine, aspirin, codeine, DMT, ethylone, heroin, ibuprofen, lisdexamfetamine (Vyvanse), MDA, MDE, MDMA, MDPV, mescaline, methamphetamine, methylone, modafinil (Provigil), morphine, oxycodone, sugar, xylazine


While reagent testing is the best method for on-the-spot testing, it is never 100% conclusive. There are many variables that can impact the reaction. 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.

Review for Marquis Reagent
Good Starting Point
Good first reagent to use for testing a substance. Works perfectly well. My only qualm is that the label was already partially peeled off the dropper bottle when I received it and the desiccant in the packaging (vermiculite I believe) stuck to the back of the label, making it hard to stick back on. This was the case with all my reagents. I would recommend stronger glue on your labels or a silica gel desiccant to avoid the mess.

Thank you for the review and info. We recently switched over to some new labeling that didn't quite work out as expected. Future shipments shouldn't have any issues. Sorry for the inconvenience.

Review for Marquis Reagent
Definitely not a chemist
I guess I just had a hard time telling the difference between tones of brown. Ran other tests to make sure it at least wasn't fentanyl....but still wondering...can sugar make you trip?😁
Review for Marquis Reagent
Great product
Easy to use and very easy to read the chart. 100% recommend.
Review for Marquis Reagent
Works pretty well
Works just like I expected. One thing that I will say though is that when testing blotter paper (such as for LSD) I did get a slight brownish color that matched the sugar. I got this even though I was fairly certain it was LSD (based on the other reagents I used). I'm assuming that there's something present in paper naturally (maybe something like starch) that causes this slight brownish color when mixed with Marquis. Just something to be aware of when testing blotter paper with this. ------------- Reply from Test Kit Plus:

Thank you for the review. While the Marquis test can be used to screen for psychedelic amphetamines sometimes missold as LSD, we recommend testing for LSD with the Ehrlich test. You may also be interested in our LSD Test Kit package.
