The online chart says Marquis turns the substance light pink (or no change) for cocaine but the sheet with my order is just no change. 21. January 2020

Cocaine often contains impurities from the coca plant in small amounts and these go pink. In the online chart for all substances we have chosen to include this under “cocaine” but on the paper chart it’s a separate row because less substances need to fit onto each page.

What test would I need to check speed/amphetamine? Like to make sure it’s not mixed with bleach or some other crap? 21. January 2020

Marquis reagent should go orange for amphetamine, froehde and mecke should not change colour. These three are in the MDMA testing multipack. Liebermann is nice to have to detect unusual additions of cathinones. You should dry it on a radiator first. No reagents will change colour for caffeine, a common adulterant of amphetamine.

How can I contact you? 12. January 2020

Please email askme@reagent-tests.uk

I’ve twice asked “Are these reagents legal to delivered to my home address in the UK as someone said they were not” and no response yet there are multiple other answers afterwards. 8. January 2020

Yes, they are legal. You can see that this has already been answered on this page, hence why your question was only left up for a week. Please call or email us if you need more detail or cannot check back within a week. legal@reagent-tests.uk

What reagent is useful to detect possible MDA in a sample of ‘MDMA’ or even detecting APB or a APDB? Thanks 6. January 2020

This is tricky, you would need to use both the robadope reagent and simon’s reagent, each of which is a two-part reagent. Unfortunately we don’t stock these because of the extreme rarity of MDA in europe, which means that it is more expensive and therefore never added to MDMA or sold as MDMA.

Do the kits go off outside the fridge? I plan to carry them in my luggage while I go travelling across europe. 6. January 2020

The shelf life varies for each one and even then it’s affected by humidity, temperature and oxygen exposure. Our 18*C tests reveal

  • Froehde – over 18 months,
  • Ehrlich – around 1 year,
  • Liebermann – just under 1 year,
  • Marquis – 6-9 months,
  • Mecke – 5-7 months,
  • Mandelin – 5-7 months,

How can I test for presence of speed with MDMA 26. December 2019

Our MDMA reagent testing kit can show the presence of amphetamine added to MDMA. Pick out visually different particles and test them separately to see a clear difference in the test results. Don’t forget to read the instructions – you only need a few specks of the drug.

Can I track my order? 26. November 2019

Please log in to your account or contact us if you did not make an account when you placed the order.

how long do the test kits last for? and how should i store them? 19. November 2019

They last about 12 months when kept upright in the fridge.

Are reagent tests illegal in the UK? 13. September 2019

You must have “good reason” to carry these tests in public. “I am on my way home from a party where I was helping people be safe” is an acceptable reason.

Testing kits are not illegal to own. If you ever get in trouble for them please contact us and we may be willing to contribute to legal fees for you.

What kit is best to test ketamine? 1. August 2019

The Liebermann reagent is the only one that gives a truly consistent reaction with ketamine but it is a faint yellow. The mandelin reagent usually goes orange with ketamine, sometimes it does not change though. The marquis reagent gives no colour change with ketamine but does react with some impostor substances like 3-MeO-PCP.

The cocaine testing multipack we offer contains all three of these.

How do I know if the bottles are inaccurate/out of date? 28. July 2019

You can test your reagents using common drugs like paracetamol, ibuprofen and aspirin. Check out the reaction results & instructions page for more information.

Can i take this on the plane? 3. June 2019

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 the lid is on tightly and they are individually bagged as they will damage your luggage if they leak (due to the reduced pressure in the hold). They can be safely transported individually bagged in hand luggage with your other liquids, again airline regulations permitting.

How will an order show up on my bank statement? 13. April 2019

An abbreviation of the company name. No product details.

Is packaging discrete? 8. January 2019

It’s a 25mm white box with nothing but your name and address on it.

My bottle isn’t full up to the top 5. January 2019

We package our 2 mL portions of reagent into 5 mL bottles to ensure more consistent drop rate as the bottle empties. The 2mL of liquid in the bottle will still give between 30-40 tests, as advertised.

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.

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 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.
