Because Marquis is often used as a broad test, we recommend using other reagents as a follow-up. Use our Reagent Tool to determine which reagents would be best. Our Complete Test Kit covers all bases and is our most popular product.
First discovered in 1896 by Eduard Marquis, the Marquis reagent has grown to become the world’s most commonly used reagent. It contains Formaldehyde and Sulfuric acid.
Consider upgrading to the Complete Test Kit to narrow down what your sample is.
It’s worth knowing.
In a unregulated market there is no way to ensure what you’re buying is actually the intended drug, but with the use of test kits you can test your drugs and see what it actually is.
With the growing trend of “research chemicals” being falsely sold, testing your drugs has never been more important.
How to use
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.
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.

Together we can save lives ❤️
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.
