The Test Your Poison Fentanyl Test Kit is a quick identification test that will show the presence of fentanyl. With this test you are able to find out whether fentanyl is present in your sample. Dealers cut substances to increase the profit margins. The substances used for cutting are generally harmless but sometimes can include dangerous/harmful substances such as fentanyl. It is important to stay clear of substances cut with fentanyl.


This identification test will also show the presence of Oxycodone (Oxycontin®), Heroin, Morphine, and Codeine.

    How do I use the kit?

    Instructions on performing the test are included with your test kit. We’ve also included them on the product pages. You can also click here to find out more.

    How much of the sample should I use?

    A very small sample is sufficient. In general, your sample should be about 20mg or 1-2 drops.

    My vial looks empty, can I still use it?

    Some of our test kits require very minimal reagent to be effective, while other kits require more. Depending on the kit you buy, there might seem like very little reagent (few drops). Do not worry, as this is intentional. Some kits are designed to have that amount of reagent, and you can still use it.

    How reliable are the tests?

    While reagent testing is the best method for on-the-spot testing, it is never 100% conclusive. There are many variables that can impact what the reaction looks like. Lighting, impurities, and unwanted substances in your sample may all play a role.

    Poorly designed product with unclear instructions

    Broke easily, difficult to understand how to use. When I reached out to customer support to better understand, was referred back to unclear written instructions that were even difficult to find on the website. Unable to use test, no refund available

    Hi Jordan, thanks for taking the time to write a review, we're so sorry you're unhappy with your purchase! We've checked on our end and can confirm we responded to your concerns on July 5th via email. We simplified the instructions and provided references on how to use our test kits with video. All our kits have instructions that can be found with each product order, on each product page, and on the How To Use section of our website (with videos). We are only able to provide refunds on returned products. We are sorry that you had a difficult time using the kits, and would appreciate feedback on how we can make our test kit instructions easier to interpret.

    Little confusing at first but worked great


    I didn’t receive a full kit, the solution wasn’t in the package so I didn’t use it obviously. The Cocaine Purity test was worth the purchase though.


    I bought MDMA at a music festival and thank god I bought this kit. It was laced. I cannot stress enough how grateful I am to have come across this company. Thank you test your poison!!!
