The Simon's Reagent kit is a secondary test (after Marquis, Mecke, Mandelin) that tells the difference between MDMA and MDA, between methamphetamine and amphetamine, or between MDPV and methylone. 

The kit contains two bottles (Simona A and Simons B) with enough reagent for approximately 50 tests.

Simon’s reagent is sodium nitroprusside in a basic buffer. It works by detecting ‘secondary amines’, such as the ‘meth’ in METHamphetamine and in mythylenediaoxy-METHamphetamine (MDMA). We use it after testing a substance with Mandelin, Marquis or Mecke Reagent.

If a substance tests positive for an ecstasy-like substance by turning to purple/black with Marquis or Mecke, or to blue/black with Mandelin, then a color-change reaction with Simon’s indicates the presence of MDMA or MDE.

If a substance tests positive for a speed-like substance by turning orange with the Marquis reagent, then a color-change reaction with the Simon’s indicates the presence of methamphetamine.

If a substance tests positive for a cathinone substance by turning yellow with Marquis or reddish-brown with Mecke, then a color-change reaction with Simon’s indicates the presence of methylone or butylone.

Testing Instructions

Instructions are also included inside the packaging for the reagent.
The Simon’s reagent actually consists of two reagents in two, separate bottles, marked “A” and “B”. Bottle “A” has a yellow label, and bottle “B” has a green label.

This test is to be used only after you have first received a positive result with Mandelin, Mecke or Marquis reagent. It should never be used alone. Always use one of the other reagents first to identify the presence of a particular set of substances Only afterwards should you use this test.

Never have more than one reagent bottle open at a time. If you mix up the caps and put the wrong cap on the wrong reagent bottle, this may cross-contaminate the reagents and ruin them. Be sure to perform the tests in a well-lit location.

  1. Scrape a tiny bit of your pill or powder onto a large, white ceramic plate. Use just enough powder to see on the plate.
  2. Take reagent bottle “A” (the yellow label) out of its plastic safety container. Remove the cap and turn the bottle upside-down a couple inches over the powder. Squeeze one drop out of the bottle onto the powder. Be careful to not let the dropper bottle touch your powder or you will contaminate and ruin the rest of the reagent. Replace the cap. (Note: The reagent can be a dull sea-green color. This is just the color of the solution in bottle “A”, and does not indicate anything yet. It is only after the second solution is mixed with the first that you need to observe a possible color change.)
  3. Take reagent bottle “B” (the lime-green label) out of its plastic safety container, remove the cap and add a drop of the solution into the same powder/liquid already on the plate from step 2. Replace the cap and put the bottle back into its safety container.
  4. Observe the color change right away. Use the Simon’s column of the color chart included with your kit (and below at the bottom of this section) to evaluate your test.

Note: In some kits, solution A may be a dull sea-green color, or it may be clear. This is normal. What you’re looking for is a change in color. In all cases, the presence of MDMA/MDE/Methamphetamine/methylone will be indicated by a change to a bright cobalt blue. If no color change is observed when solution B is added, then the substance contains MDA, amphetamine, or MDPV.

A positive or negative reaction for a substance does not indicate that a drug is safe. No drug use is 100% safe.

Frequently Asked Questions

What are the known limitations of these kits?
The drug test kits by dancesafe are presumptive tests. This presumptive home drug checking, also known as pill testing or adulterant screening, is just a harm reduction service, and may not provide 100% accurate results.
A specific reagent in a kit will only check for presence of a specific substance or set of substances that it can test for, but will not indicate presence of other substances that this reagent is not designed to check. The reagent test can not indicate the quantity and purity level.
The instructions and color codes are also subjective, and may cause confusion and inaccuracy in reading the results.

How are the packages shipped?
All packages are shipped in a non-branded discreet packaging. Each package includes the instruction cards, in addition to the reagent.
