The froehde reagent has a longer shelf life than the liebermann reagent (and marquis actually). We would argue that the ehrlich reagent is completely essential if you are working with anything on blotter. What’s most important is that they detect the adulterants that you are expecting.
The “Blue > Purple > Black” bit indicates that the sample will start blue then change to purple, then black. For pure samples or large amounts, this colour change can happen extremely quickly and it looks like it just turns black straight away. Try running the test with 1/5th of the amount in the future, it really takes a tiny amount when testing crystals. Sorry that the arrows are unclear, we had never thought about it that way.
The “order complete” message indicates that we have finished processing the order and it has sent, it should be with you within the time stated in your delivery option.
In theory, anything could be cut with anything. We haven’t seen crystal MDMA cut with fentanyl in the UK yet but it has been happening in North America.
DMT is challenging because it’s a plant product which tends to mean that there are other compounds present. The ehrlich reagent will alert you if there is no DMT present (DMT turns ehrlich purple) and then it would be wise to just follow up with others to give further information. Marquis goes yellow > brown, froehde goes yellow.
Our strips have been verified to detect fentanyl, acetylfentanyl, furanyl fentanyl and 4-FiBF. Dissolve your compound in 1mL of water and dip in the strip according to the instructions on the pack. If these compounds are present they will be detected.
Of course, if you are unhappy with your purchase we also offer a no hassle returns policy, just get in touch by email :)
Hi there, that email doesn’t seem to be working, please send us an email to admin [at] reagent [dash] tests.uk

All drugs are dangerous, so of course the safest thing to do is avoid all of them. However, if you have bought a drug and plan to take it, then we’re past that point and trying to make it safer. Essentially, if you get any reaction which you don’t expect, you should discard the sample. If the person who sold it to you lied about or worse, didn’t know what it contains, can you trust them in the slightest to be responsible for your health? No!
We have received your order and will dispatch it in the next few days.
The liebermann reagent is able to do this, but bear in mind that MDA is extremely rare on the European market.
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.
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.
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.
It’s a plain white box with your address and a stamp, no signature required and fits through any letterbox over 25mm.
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!)
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.
The bottles have a built in dropping system so do not need pipettes
Definitely! We love talking about testing, please email admin at reagent-tests.uk.
The ehrlich reagent may be slow enough to need observing over 2 minutes but none of the other reagents are – 60 secs is plenty.
