What are testkits?

Testkits are chemical solutions, which react to substances and form colors depending on which substance it's reacting to.

How do I use testkits?

There are three steps in using a testkit,
1: Prepare a tiny (Approximately the size of a matchstick head, or grain of rice) bit of your drug on a white ceramic plate or mug.
2: Open your bottle and tilt your bottle over the sample so a drop falls on it.
3: Look at the color reaction that occurs and search for your result at

Which test kit do I need?

Don’t know exactly what you need? Marquis is a common first testkit to use, and suitable for substances like Cocaine, MDMA, Amphetamine and more. We also have Substance specific Testkits which you can find here.

If you want to test psychedelics such as LSD, DMT or mushrooms then the Ehrlich Test Kit is what you need, further testing with other reagents is necessary to be able to conclude which substance it is as Ehrlich only reveals that it is an substance within the indole drug class.

Looking for a more comprehensive test? Our 7-in-1 Complete Test Kit includes an selection of reagents with the most logged reactions, giving you the best chance at finding out what is in your sample and possible adulterations.

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


What payment methods do you accept?

We accept both Mastercard & Visa as Credit Card payments.

My payment is not going through?

If your order isn’t going through, then you need to contact your bank to find out the reason why.
The most common reason for a transaction being declined is that ur bank declined the transaction due to it being a international purchase.
We suggest contacting your bank who are able to sort it out, but if that takes time and you’d rather order now then you could always use a friends card instead.


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.

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 much does shipping cost?

If you are in USA, or a European country, then shipping is free.

However if you’re in any other country then we ship via FedEx and the fee varies depending on country and location, but generally it’s about $20.

Where do you ship?

We proudly ship to every country in the world!

When will I receive my order?

Ordering from USA? We ship locally from California, and your shipping is free, and usually takes 1-5 days. Right now during Covid-19 it may take a few days longer. We ship from California, so the closer you are to us, the shorter time in transit your package will have.
1-2 Day Express is available if you are in a hurry!

Ordering from Europe? We ship locally from our European Warehouse, and your shipping is free, and usually takes 5-14 days.
There is a option to choose shipping from FedEx, if you want it tracked & insured, however you may need to pay taxes as it would then be shipped from USA, instead of Europe.
Please do note that now during Covid-19 related delays, international air transports are effected and some routes in Europe aren’t as quick as they used to be, we do still see some longer delays. So do choose FedEx shipping if you need it guaranteed in a few days.

Ordering from Canada, Australia or any other countries?
We offer FedEx Economy & Priority, which will usually take between 3-8 days, and you can check how many days it will take just for you on the checkout process!
