Tests for the presence of MDxx, DXM, 2C-B, speed and more. The Marquis Reagent is a mixture of concentrated sulfuric acid and formaldehyde. The Marquis reagent is a very good field test for a wide variety of substances and can be used in conjunction with our Simons reagent to tell the difference between MDA and MDMA/MDEA, or between methamphetamine and amphetamine, or between MDPV and methylone. Remember these tests work by identifying the presence of a substance so using more than one test can help you narrow down precisely what substances can be identified. Don't worry if that is confusing, each kit includes a detailed instruction manual.

Color reactions:

  • MDxA - purple to black
  • Speed - orange
  • DXM - grey to black, releases a slight bit of smoke
  • 2C-B - Yellow to green over 30 seconds
  • 2C-T-x - Orange to salmon
  • MDPV, methylone - Yellow
  • 6-APB - Rusty brown
  • MDMA, MDA, and MDEA - purple to black.
  • Methamphetamine and Amphetamine - Orange
  • MDPV and methylone -Yellow

Testing Instructions:

  • Full testing instructions will be included with your kit as well as everything you need to help make educated choices. The basics are exactly as you would expect them to be for a quick and reliable test. Scrape a tiny bit of your pill onto a large, white ceramic plate (an amount about the size of the head of a pin is fine). If you have a gel cap, just use a small amount of the powder. Take the reagent bottle out of the plastic safety container. Remove the cap and turn it upside-down over the powder. In a few seconds a drop will come out. Observe the color change right away. Use the included Marquis color chart and the Marquis color change descriptions to evaluate your test.


  • It's important to store your reagents in very cool and consistent temperatures. The best place to store your test kits are in the freezer, although a refrigerator or cool climate controlled room will work. Proper storage of your test kit will prolong the life of your kit of up to one full year.


  • Our Bunk Police Marquis reagent kit is made with primarily sulphuric acid and is strong enough to burn skin and clothing. It's important not to get it on your skin or in your mouth. If you get any on yourself wash with soap and water. Do your best to keep all contaminants away from the bottle and the cap.
