About this kit

Our cocaine testkit contains a selection of reagents, chosen specifically to help you identify the most common adulterants/substitutes you may find in your cocaine.

With the help of Robadope, Liebermann, Froehde and Mecke testkits along with our results tool, you can better understand the contents of your next bag to protect yourself and your friends from any nasty surprises. Otherwise, you may be risking an unexpected dose of MDMA, ketamine or speed, or getting ripped off with a bag full of caffeine or aspirin (we go into this in a lot more detail in our article, What’s in your Cocaine?).

To analyze a wider variety of substances and rule out more uncommon adulterants, check out our Complete Testkit, which also includes five other testkits.

Why test

In short, to make sure you’re getting what you wanted. Whether through malice or sheer accident, it’s easy to end up with an entirely different substance to the one you were expecting, and that goes for any drug.

As with any drug that has such a global supply chain (see also: heroin), cocaine passes through a lot of hands before it reaches you and they aren’t always people you’d want to entrust with your safety. While there are obviously extreme cases reaching 0% purity, 25-30% purity is entirely commonplace and raises the question of what else you’re taking.

Ordinarily, this is low-risk stuff like aspirin or local anaesthetics like benzocaine (which has neither the effects of cocaine or benzos, it’ll just numb your nose), but there are no shortage of Jesse-from-Breaking-Bad style dealers who have been known to “spice up” their supplies with all the confidence of a master chef and none of the knowledge. Samples have shown the presence of everything from meth and speed to ketamine at times, which certainly would add a certain jouissance to proceedings, but probably not one you’d enjoy if it caught you unawares.

And of course, we can’t ignore the possibility of fentanyl turning up. While many initially dismissed these claims as ludicrous scare tactics, more and more cocaine samples are testing positive for fentanyl. While this isn’t currently considered prevalent enough to include fentanyl test-strips in the core kit, every order you purchase will come with free fentanyl tests as a matter of course and you can buy more here.

How to use

1. Prepare
Prepare a tiny bit of your drug on a white ceramic plate or mug.
Tip: You should use the same amount of powder as on a matchstick head, or a grain of rice. If you’re testing blotters, use 1/6th of a blotter.
2. Test
Simply remove the cap from your bottle and tilt it until a drop falls out.
From the moment the testkit liquid hits the sample, watch closely for 30-60 seconds for any colour changes.
Tip: Many samples will have an initial colour change followed by another over time, so it’s important to keep a close eye on them.
Make sure that the sample doesn’t touch the bottle tip.
3. Search

Common questions
Is it safe shipping testkits and are your packages discrete?
Testkits are a legal product, and commonly used by harm reduction organizations.

We do not ship the test kits with anything that hints towards substance use, such as reaction cards, a receipt with a link to our site and even use abbreviations for the labels instead of the reagent’s full names.

So to put it simply, all our orders are packaged extremely discretely and with care of privacy.

How long do testkits last?
One year is to be expected in optimal storage conditions but shelf life varies with each reagent as well as to what conditions you have stored them.

Keep the test kits out of light, in cold storage and do not leave the bottles un-capped any longer than necessary.

To see if your test-kit is still valid after long term storage test common substances like Vitamin C, Aspirin, Ibuprofen, Paracetamol or any known substances (i.e an sample you know for sure is a certain substance) and see if the reaction is correct in reference to our reagent tool

Where does my order ship from?
DoseTest is a multi-national company, so we have distribution from both Europe & the United States.
All European orders are shipped from Europe.

All USA and orders from other countries are shipped from USA.

Can I get help when testing?
Ofcourse! We have a live chat on our website, where you can talk to us incase you need any assistance when testing or have any questions.
How can I test cocaine for fentanyl?

The best way to test your substance for fentanyl is by using fentanyl test strips! They are very sensitive, and can detect multiple fentanyl analogs (see our page on testing for fentanyl).

Can this kit detect methamphetamine?
Yes! Each of the three reagents (Marquis, Mandelin, and Liebermann) react differently for methamphetamine and cocaine, allowing you to see if methamphetamine is present in your sample.
Is it hard to conduct tests?
The actual process of dropping the reagent onto the sample is easy! What may be difficult is knowing which reagent to begin with, and how to interpret the results. Here at DoseTest we have created the Results App which should make interpreting the results easy! We also have a live chat where you can ask any questions about testing!
Our Harm Reduction

DoseTest is here to shake up the harm reduction world, taking lifesaving materials like reagent test kits and fentanyl test strips from the small niche where they have lived and making them accessible to everyone. This doesn’t just mean selling them cheaper than everyone else, though. It means meeting people where they are and advancing both the materials and the information about how and why to use them. It means working together with everyone from state health departments to mutual aid groups to reach people that we never could alone.
