Is a fast dark reaction to all 3 of your mdma tests pretty conclusive? Are other colours you show on your card pretty obvious when they appear? or can the differences be pretty subtle 19. October 2017

Three fast, dark black reactions is pretty conclusive but remember that reagent tests are not £100k GC/MS systems and they are not perfect. Even if there was no other colour change (subtle or otherwise) then that is not a guarantee of safety, just a higher chance of it. It’s like when you open the 1p box on “deal or no deal” – it’s not a guarantee you’re walking out with £100k, it just increases the chances.


I have tested MDMA with the Marquis test and it went from dark brown to black over about 5 seconds, does this mean there is MPA and MDMA in the sample? 18. October 2017

It suggests that MDMA is probably present in the sample but there is no way to guess if anything else is present if you have only used one reagent – this is why we feel it is very important to use multipacks, there is too much uncertainty from a single reagent if the reaction is not perfect.


What does “order processing” mean? 14. October 2017

We have received your order and will dispatch it in the next few days.


What particular benefits does using both Marquis and Froehde reagents have in addition to the Ehrlich reagent when testing LSD? 18. September 2017

These allow better determination to see if there is anything else on the tab other than LSD, and whether the compound that has given a positive reaction is indeed LSD or a related compound.


There seems to be little to differentiate between MDMA & MDA – what do you suggest? 15. September 2017

The liebermann reagent is able to do this, but bear in mind that MDA is extremely rare on the European market.


Can you tell me if any of your tests will show the difference between MDA and MDMA ? 23. August 2017

The liebermann reagent is able to do this, but bear in mind that MDA is extremely rare on the European market.


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.


Does your precision weighing scale requires calibration? If yes, what weight? 17. August 2017

The scales are pre-calibrated but come with a 20g weight. You can hold down the “mode” button to select calibration, then press again, wait and add the 20g weight. This will reset the balance if it has become inaccurate.


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.


Can you take reagent tests kits on a plane? 9. August 2017

The kits are not illegal but this will depend on your individual airline. You should make sure they are transported inside their individual bags and stored upright because the low pressure on a plane can make them leak a tiny bit.


Would you reccommend using the fentanyl test strip to check MDMA samples (along with the MDMA test kit), or is it unlikely to be be found in MDMA sold in the UK? 11. July 2017

As far as we are aware fentanyl has not been found in any samples of MDMA in the UK. That does not tell us anything about how many samples could contain it in the future though so we can’t make a recommendation about this as such. It still seems the greatest risk for people who use MDMA is taking too much MDMA or a more typical adulterant/mis-selling.


What substances other than fentanyl and/or fentanyl analogues will your product “Fentanyl Test Strips” detect? 26. June 2017

The fentanyl strips are only for detecting fentanyl at this time.


How discrete is the packaging? 16. June 2017

It’s a plain white box with your address and a stamp, no signature required and fits through any letterbox over 25mm.


My reagents just completed one year since its first use and have been always kept in a sealed container. I tested with paracetamol, sugar and MDMA and it gave the results as per reference table. Can the reagents last for more then 12 months? :) 9. June 2017

What kills reagents is moisture, oxygen and heat – the more you can keep these away, the longer the reagents will keep. This means that in some circumstances they can happily last 18 months or so. Well done for checking!


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!)


Would storing your reagents in the freezer prolong the shelf life if you use them very infrequently? 29. April 2017

We don’t recommend freezing because the reagents can freeze and precipitate (un-dissolve) parts of the mixture.

Froehde and ehrlich aren’t susceptible to this and colder temperatures will slow down the reactions that cause them to degrade. Ensure they are in a sealed bag and are allowed to warm fully to room temperature before opening the bag.


In the MDMA kits, do you need to test the pill or powder with all three Reagents? Or can can you use different ones for different times 24. January 2017

It is strongly recommended to use more than one different reagent per sample as it gives the best chance of detecting something unexpected.

For example, a cocaine sample cut with paracetamol would show no reaction with the marquis reagent, but an obvious green result with mandelin.


Do these come with pipettes? 18. January 2017

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


Is it necessary to keep the bottles in the fridge? How will this affect the reliability / shelf life of the products? 15. January 2017

The reliability will be the same but the reagents won’t last quite as long. In our experience they will usually still get pretty close to a year but even at the best of times the shelf life varies so it’s hard to give a specific number. We find the froehde reagent lasts more than a year even when it is not refrigerated and the same for the ehrlich reagent – the reaction just takes a little longer.


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.
