The Complete Set contains all nine of our reagent kits. This includes all of the reagents included in our MDMA, cocaine, ketamine, and LSD kits, as well as the additional reagents Mandelin, Folin, and Mecke.

Each kit performs 50-75 tests. Includes full instructions, plus two fentanyl test strips and one amphetamine strip.


Contents of the Complete Set

Marquis Reagent: Marquis reagent is the first step in both our MDMA kit and the second in our cocaine kit. It is especially effective at reacting with amphetamines, including MDMA, amphetamine, and methamphetamine.

Simon’s Reagent:Simon’s is a secondary test that is almost always used alongside at least one other reagent. It is one of three reagents in the MDMA kit. Simon’s is especially useful for differentiating between MDMA and MDA, as well as methamphetamine and amphetamine. Simon’s reagent consists of two bottles, A and B, which are used together as a single test.

Froehde Reagent: Froehde is a versatile reagent that’s also included in our MDMA kit. It produces several unique color reactions with unusual substances, including 2C-B, mescaline, and some cathinones.

Morris Reagent: Morris is currently the only kit on the market able to distinguish ketamine from DCK, 2-FDCK, and other novel dissociatives. Morris also turns a bright Jolly Rancher blue in the presence of cocaine. It consists of two bottles, A and B, which are used together as a single test.

Liebermann Reagent: Liebermann is helpful for identifying the presence of possible cocaine adulterants like levamisole. It’s the second step in our cocaine kit, and is also useful for testing substances like amphetamines, ketamine, and more unusual drugs.

Mandelin Reagent: Mandelin reagent can be used as an additional layer of testing for a variety of drugs, providing more information when other reagent tests doesn’t go as expected. Shake well before using.

Mecke Reagent: Mecke can be used to perform more specialized and complete testing, especially when testing unknown substances.

Folin Reagent: Folin is primarily useful for detecting a class of drugs called piperazines, which includes BZP and TFMPP. Folin reagent consists of two bottles, A and B, which are used together on a single drug sample.

Ehrlich’s Reagent: Ehrlich’s turns purple in the presence of a class of drugs called “indoles,” which includes substances like LSD, psilocybin, DMT, and more. If Ehrlich’s does not turn purple, it means that no LSD is present. Ehrlich’s should only be used to test substances sold as LSD.

What are reagents?

Reagents are chemicals that turn certain colors when they come into contact with certain drugs. Reagents cannot detect every drug, nor can they tell you how pure or potent your drugs are. Even if you get the expected color reactions for the drug you want, there could still be one or more other drugs present. This is because:

  • Not all drugs change color with reagents.
  • Darker colors may overshadow lighter colors.
  • A very tiny quantity of a drug may not produce a visible color change.

Despite these limitations, reagent testing is useful for determining whether your sample definitely does not contain the drug you want.


  • Detect the presence of certain drugs
  • Give you information about whether a drug is suspicious
  • Inform your decision about whether or not to consume a drug (“informed consent”)


  • Tell you how potent your drugs are
  • Tell you if your drugs are pure
  • Confirm exactly what is in your drugs

How to use reagents

A graphic of how to test drugs with reagents, including images of the size of samples you need for different substances.1. Place a tiny amount of your drug onto a white, ceramic plate.

  • Make it about the size of a pinhead. We will refer to this as the “sample” of your drug.
    • For pressed pills, use a sharp knife to scrape the powder off the side.
    • For blotter paper, cut off a tiny piece of the corner.
    • For liquid drugs, place one drop onto the plate.

2. Carefully place one drop of reagent onto the sample.

  • Do not let the bottle touch the sample or you will contaminate the entire bottle of reagent.
  • If you are using a 2-bottle reagent such as Simon’s, Folin, or Morris, place one drop from bottle A and then one drop from bottle B onto the same sample.

3. Observe the color change and compare with the enclosed color chart.

  • Most reagents will change color within twenty seconds.
    • Ehrlich’s reagent can take up to 5 minutes.
  • Morris reagent is the only reagent that needs to be stirred. Use a toothpick or the sharp point of a knife.
    • The final color will appear after stirring for a full 30 seconds.

4. Repeat.

  • Most drugs need to be tested with more than one reagent.
  • When using multiple reagents:
    • 1. Put the cap back on the first reagent.
    • 2. Repeat the process using a new sample for each reagent.

5. Clean up.

  • Use baking soda to neutralize the chemicals, then wash the plate with soap and water.

How to read reactions

Be aware: There are over 25,000 drugs on the market, and there are many factors that can influence a reagent reaction.

When you’re reading the color chart, it’s very important to remember that you’re looking for red flags, not green lights. You should see whether the color reactions you’re getting are “as expected” for a given drug.

If any reactions are unusual, the reaction is “not as expected.” It’s impossible to know which of the six factors listed below have caused an unexpected reaction without sending the sample to a lab like DrugsData.

Things that can cause an unexpected reaction:

  1. Leftover precursors (ingredients used to make a drug)
  2. Impurities from the manufacturing process
  3. Adulterants (active drugs cut in, like meth in MDMA pills)
  4. Bulking agents (inactive drugs cut in, like supplements)
  5. Mixtures (multiple things in the sample)
  6. Analogs (drugs that are very chemically similar to a more popular substance, and might react almost exactly the same despite having different dosages or effects)

Example: MDA has recently been turning green/black with Simon’s reagent instead of not reacting. Cocaine used to not react at all with Marquis reagent, but in recent years it almost always turns a pale peach or pink color. We suspect that this is due to a change in how both drugs are being made.

Example: When testing an MDMA pill, an “expected” reaction would be Marquis turning black, Simon’s turning blue, and Froedhe turning black. If Marquis turns orange instead of black, this is an immediate sign that there’s definitely no MDMA in your sample.

Example: When testing an Adderall pill from the internet, an “expected” reaction would be Marquis turning orange, Simon’s not reacting, and Liebermann turning orange. If Marquis turns orange, Simon’s doesn’t react, but Liebermann turns black, you know that something is wrong, but you don’t know what.


It might be tempting to try to make guesses about why you got an unexpected reaction, but you are always missing information without a full lab analysis. Even DrugsData can’t tell you whether there are inert bulking ingredients in your drug. It is sometimes possible to make educated guesses, but we usually find that those guesses are disproven by actual lab analysis.


Below are reactions for some of the most commonly used drugs. There are many online resources where people have collected additional reagent reactions for other drugs, but we haven’t verified them.

2023 updates:

  • A dark gray/green reaction on Simon’s reagent is now an expected reaction for MDA.
  • A light pink or peach reaction on Marquis reagent is now an expected reaction for cocaine. (Use the “how to test cocaine” insert on the pamphlet for more detailed information.)

Storage & handling

Keep reagents out of heat and sunlight to make them last as long as possible. Storing in a freezer is ideal, but a fridge works too.

If stored in a refrigerator or freezer, most reagents have a shelf life of at least a year. (Make sure to thaw them out to room temperature before use.) Try to dispose of unused reagents at a hazardous waste facility.

  • Mandelin reagent starts out light orange in color and turns cloudy yellow after 3-4 weeks. This is okay. Make sure to shake the bottle before each use.
  • Marquis and Mecke reagents begin as clear liquids and gradually darken over time. This is okay. They are only expired when the liquid in the bottle becomes so dark that you can no longer see the color reaction.

cautionIf contact is made with the skin, wash with water immediately. If it gets in the eyes, flood the eyes with water for at least 10 minutes, holding them open. If accidentally ingested, rinse the mouth. Do not induce vomiting. Drink water and seek immediate medical attention.
