how does it work (eg. using ehrlich reagent on LSD?) 13. May 2018

Using the reagents is really simple, more information can be found on our instructions page, and paper instructions also come with the kits.


Can you use to test for a fent cut in Heroin? 6. May 2018

Yes, a fentanyl testing strip can test for the presence of fentanyl added to heroin or any other drug.

Can test results for cocaine be used to determine purity? 1. May 2018

Unfortunately reagent tests can’t give a percentage purity. The knowledge of whether cutting agents are present can help accounting for strength but it’s not possible to detect exactly how much cocaine is present as well.

How long do kits last without a fridge? 11. March 2018

Depending on storage conditions (high temperature), how often they are opened (high moisture) we would expect them to last for 50-75% of their normal shelf life. The froehde reagent is most resistant to higher temperatures


What test could I use to distinguish between MDMA and MDA/MDE? 6. March 2018

The liebermann reagent can do this but MDA is very rare on european markets

When testing with multiple reagents for PMA and PMMA if there is even a small amount of MDMA in the sample will the black/purple colour that presents for MDMA over ride the paler colours or is the colour quantitative? 6. March 2018

The colour is quantitative, but you are correct to note that PMxA has a paler colour so a 50/50 mix perfectly mixed with MDMA would probably be hard to detect. However, if it was a mix of two types of crystal then you can often see the difference between that and a pure sample.

I want to test whats in some supposed xanax tablets. Which kit should I buy? 5. March 2018

Unfortunately benzodiazepines are quite nonreactive and as a result there are almost none that give a colour change with reagents. The main concerns with counterfeit pills is them having a much stronger effect than normal and so this can only be done with lab measurements. The presence of fentanyl can also be a concern, you can dissolve the tablet into vodka and use our Fentanyl Testing Strips to check for this.

How do you dispose of old test kits? 3. March 2018

While wearing gloves and eye protection, start the cold tap running gently and then remove the lid of the reagent bottle and upturn it so that the contents drip into the flowing water. As soon as they are diluted, the risks are very low but it is not safe to drink or wash in the water.

Is the package plain and discreet? 3. March 2018

Yes, extremely discreet and the only thing on the outside is the address and postage sticker. Please check our shipping info page for more information.

Can I fly with a test kit? Has anyone run into issues at airport security/airlines? 24. January 2018

You would have to check the regulations of your airline but if you do, it is best to put them in checked luggage and make sure that they are double bagged as they will damage your luggage if they leak (due to the reduced pressure in the hold).

which test kit is used for ketamine? 23. August 2017

Ketamine itself doesn’t give a colour change with any reagents but cutting agents do – the cocaine testing multipack is actually most suitable for this as some preservatives in vetinary ketamine give a faint orange reaction with the mandelin reagent and a faint yellow with liebermann, which is a helpful identification hint.

What happens if a sample contains multiple drugs? 14. August 2017

It will produce a mixture of the colours – a lot like mixing two colours of paint. If you have a powder or crystalline substance with two different looking types of crystal, try to separate them and test them individually.

Hi, how it will show the purchase on my bank state account? 25. May 2017

The statement note is discreet and cannot be linked to us through google or other search engines (and we’re not going to post it here for exactly that reason!)

Do these come with pipettes? 18. January 2017

The bottles have a built in dropping system so do not need pipettes

Can I send you a photo of my test result for clarification? 30. August 2016

Definitely! We love talking about testing, please email admin at reagent-tests.uk.

Are reagent tests legal? 1. June 2016

We are not aware of any countries in which reagent tests are illegal. The reagents are used in laboratories for testing other common compounds so banning them would be impractical.

How do you test LSD which is already on a blotter tab? 25. April 2016

The ehrlich reagent can be applied directly to blotter.

Other reagents need the blotter to be submerged in alcohol (rubbing alcohol works fine) first.

Do you offer discounts for bulk orders? 25. April 2015
