None of the tests give a numerical indication of purity. Experienced testers start to get an idea of purity from the speed and intensity of colour change but this is affected by temperature and other factors too.
The primary aim of reagent tests is to identify mis-selling incidents to avoid some of the most harmful situations concerning drug use.
The safest route is always “don’t take drugs”. When it comes to testing, ideally you should send everything for a full laboratory test. In practice this isn’t a viable option for most people.
In theory any drug could have fentanyl deliberately or accidentally added to it so you should always test. In practice contamination of LSD with fentanyl is unbelievably rare.
The reagents test for a wide range of substances – this information sheet covers what reagents can and cannot do:
Send an email to firstname.lastname@example.org and we’ll be happy to explain in more detail.
We’re not aware of any substances matching this colour profile. If the result is not what you expect then it should be lab tested even if you think you found another substance that matches.
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.
Yes, but they need to be kept upright and allowed to warm and dry fully before use. The liebermann reagent needs 24+ hours to be used as it can form crystals which need to re-dissolve. It’s not clear to us that the increase in shelf life is significant, hence why we recommend refrigeration instead.
We remove unusual questions on a regular basis so that people can find the answers to common questions more easily. Please email us if you have rarer questions or want more detailed answers.
You should not use only one reagent on any substance because two substances may have similar changes with that reagent. Always use a minimum of two, ideally three or more.
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.
You can test your reagents using common drugs like paracetamol, ibuprofen and aspirin. Check out the reaction results & instructions page for more information.
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.
The LSD-like part of 1P-LSD is prevented from reacting with the ehrlich reagent (which is used for LSD) and this causes the reaction to purple to be very slow. This makes it hard to conclusively test. We recommend ehrlich to check for other LSD-analogues being used instead of 1P-LSD and the froehde and marquis reagent to look for non-LSD-like psychedelics being added to the blotter.
LSD analogues have similar safety profiles but strong reactions with marquis or froehde are big warning alarms.
Note that microdosing solutions must be dried to a residue prior to testing.

It’s a 25mm white box with nothing but your name and address on it.
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.
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.
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.
Definitely! We love talking about testing, please email admin at reagent-tests.uk.
