We think we can all agree that prior to consuming any new substance, it is important to know whether the substance consists of what your provider claims it to be, a completely different substance, or combination of mixed substances entirely. This is where reagent test kits come into plat.  They can be used to spot-test a pill or powder  in just a few seconds to find out if it is what the provider says it is or not.  Substitutions and combinations very common for MDMA are meth/amphetamines or methylone (commonly referred to as “bath salts”), and harmful substitutions for ehrlich may be something like 25i-NBOMe.

When using reagent test kits, it is important to realize are only capable of detecting the presence of a particular substance, not its overall composition.

In addition, a substance that has been spot-tested should not necessarily be considered safe. There are many contributing factors (mixtures of multiple substances and variations in lighting, for example) that can produce varying results even with the same substance. No drug is ever 100% safe!

Why It Is Important

Reagent testing is an integral part of the first part of harm reduction. The concept of harm reduction acknowledges that people are going to engage in potentially dangerous behaviors like drug use. By focusing on harm reduction, the focus is on how we can minimize the activity’s harmful effects rather than stigmatizing people who choose to participate, or simply ignoring the issue entirely leading to physical and emotional harm and sometimes death.

When it comes to drug use, harm reduction is crucial and does save lives. Being able to spot-test substances before deciding to take them is both important and empowering. Without knowing exactly what you are about to consume, it is possible to take a dose that would be within reason for the substance that you think you have but which would result in an overdose for the substance that you actually have. In addition to determining the proper dose for a substance, reagent test kits can also help people avoid ingesting unknown and potentially dangerous adulterants found in street drugs.

Different Types of Reagents

There are various types of reagent test kits on the market. Some test for a wide variety of popular substances, while others are used to differentiate between a smaller set of substances for even more accurate identification.

Our Marquis reagent is our most popular reagent, and for good reason. It is not only the primary test for substances like MDMA (Ecstasy), it is an excellent test for many other substances including, but not limited to meth/ampthetamines, cocaine, and many more.

The Mandelin reagent is another popular reagent capable of testing for MDMA, ketamine, cocaine, heroin, meth/amphetamines. For testing the tryptamine family of substances, the Ehrlich reagent can be used. It is able to test for LSD, DMT, and mushrooms. To further test tryptamines, a double confirmation can be had with the Hofmann reagent.

The more reagents that are used, the greater the chance of eliminating false positives.  We offer many kits that are designed to be the most complete for the most popular substances.  You can find the MDMA (Ecstasy) Kit here, or the LSD & DMT Kit here.  Reagent kits not only save money, but allow for the greatest levels of at home reagent testing.


Using reagent test kits is one of the best ways to reduce the potential risks of using illicit substances. A certain level of confidence can be achieved and besides helping to prevent uncomfortable or anxious feelings, it can prevent emergency room visits or even deaths.

Frequently asked questions

It is typical that synthetic drugs in a form of salt will fizz and bubble with most reagent tests.  Reagents are strong acids and react to strong bases.  If you see only fizzing instead of color change, that can indicate presence of a new psychoactive substance.

The reaction speed does not indicate specific quantity nor purity. Results should be read at 60 seconds.

All of our bottles are good for about 200 tests (10 ml). Remember, for each test, only use one drop.

Our reagents are specifically bottled in glass bottles to increase shelf life. Reagents are strong acids and contact with plastics will degrade them significantly faster.  Always store your reagents in a cool, dark place.
