The Test Your Poison Heroin Purity Kit is a quick test for heroin that will give you an idea about its purity. With this test you are able to find out whether and how much the heroin has been cut. Dealers cut heroin to increase the profit margins. The substances used for cutting are generally harmless but sometimes can include dangerous/harmful substances. As a general guideline, you can say that when there is a high percentage of heroin present in the sample, you are close to the top source and the use of dangerous adulterants are diminished.


This purity test does not tell you anything about the identity of the substances that were used to cut the sample with.


Use this test after you’ve tested your sample with the Heroin Test Kit, which gives an indication of whether or not Heroin is present in the first place.

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.

Helps know the strength

Bought this for a friend who is using, am trying to protect them. This does a good job at letting you know how strong it is, so you can take an appropriate dose
