Let us reassure you: there’s nothing wrong with the ampoules. This is a safety feature. We have buffered a little bit of liquid in the granules you can see clinging to the side of the ampoule. This forms a kind of gel which prevents leaking in the case of breakage. This enables us to ship it worldwide and (unlike those little bottles from other reagent sellers) minimizes the risks of contact with the skin for the user.

And then some exotic, relatively new substance is mentioned…. We’re always working on new tests in an effort to keep up with market developments, but it is really difficult to get a hold of reliable samples. You are always welcome to send us a sample, with which we can experiment. :-)

Correctemundo! The natural color of this test is a golden orange yellow. This does not affect the reaction, it is supposed to be this way.

Keep the tests in a cool and dark place (away form direct sunlight) and they will stay good for minimal 3 years. Unlike the bottled reagents that are around, EZ Tests will not go off.

That is correct, you do not need the little ball anymore. We have updated the formula and do not need the little ball anymore

Please check your spam folders for an email from our shipper: KDZ, they send the tracking number as soon as they ship it.

Yes! EZ Tests can be shipped freely and without any problems anywhere in the world!

Yes of course! We’ll be happy to supply you and your shop with our fine tests! Please go to: and take it form there. Shops and other harm reduction organizations get special price deals.

Yes. Our products do not contain any controlled substances and are completely legal to own, ship, sell and distribute.

This is a difficult one, yes and no… In general a darker color will override a lighter color reaction which makes it difficult to detect mixtures. On the other hand, mixtures often cause the reaction to show a weird color so any reaction that is fundamentally different from what is indicated on the leaflet should be viewed with great suspicion. Please do not forget that these tests are meant to serve as a presumtive drug identification test. If you need to know exactly what is in a sample you should find a lab where they do GC/MS or HPLC analysis.
