Custom Reagent Test Kit includes up to 5 out of 11 reagents for over 800 substances, including 2C-B, benzofurans, cannabinoids, meth/amphetamine, LSD, DMT, dissociatives, MDMA, MDA, mephedrone and opioids. It is used to rule out U-47700, NBOMe, PMA/PMMA and other, less predictable, less desirable, highly toxic dangerous drugs. Multiple reagents are required to detect adulterants and increase analysis precision.
Reagent tests can indicate PRESENCE, but not QUANTITY. Mixtures can be detected with reagents only if adulterant causes a darker color change than the expected substance. To detect all ingredients and estimate their amount pair reagents with a TLC purity test kit.

The Custom Reagent Test Kit comes with up to 5 out of 11 reagents: Cannabis, Ehrlich, Hofmann, Froehde, Marquis, Mecke, Morris, Liebermann, Robadope, Simon’s and Zimmermann / Beam, all in abosrbent vermiculite. Included accessories are: ceramic reaction plate, spatula, gloves, instructions and app for all test kits and over 800 substances. Every bottle contains 5 ml (liquids) or 10 ml (crystals), 100 tests of each in total. High quality HDPE and brown amber glass protect reagents from light, plastic and moisture to ensure prolonged shelf life. Child-proof caps guarantee 0 spills.
-
- Cannabis (4-AP) – main test for THC / CBD, helps rule out synthetic cannabinoids
- Ehrlich – main test for all indoles, e.g. lysergamides and tryptamines but also 5-HTP and more, secondary test for cocaine
- Hofmann – main test for lysergamides and tryptamines, more precise but slower than Ehrlich
- Froehde – main test for most powders, secondary test for ketamine and amphetamines, long shelf life
- Liebermann – main test for most powders, secondary test for cocaine (detects levamisole)
- Marquis – main test for most powders, secondary test for ketamine, mephedrone and psychedelics
- Mecke – main test for most powders, secondary test for cocaine, ketamine and mephedrone
- Morris – main test for cathinones, cocaine and ketamine, can tell apart some novel dissociatives
- Robadope – main test for primary amines, e.g. MDA, amphetamine or PMA
- Simon – main test for secondary amines, e.g. MDMA, meth, mephedrone, methylone or PMMA
- Zimmermann / Beam – main test for cathinones and benzodiazepines in geneal, detects also CBD
Fentanyl Test Strip to detect fentanyl, even if it is mixed in another substance.
Reagents can indicate PRESENCE, but not QUANTITY. Adulterants can be detected with reagents only if they cause a darker color change than the expected substance. To detect all ingredients and estimate their amount pair reagents with a TLC purity test kit.

GET ALL TOOLS
First, prepare a clean white testing surface – ceramic or glass is the best, e.g. bottom of a mug or a plate. Get your sample, reagents, a sharp tool / scoop and paper towels.
PREPARE SAMPLE, ABOUT THIS BIG -> ●
If testing a pill, powder or crystal, crush it finely. If testing a blotter or gel tab cut off 1/8th (a corner). If testing a liquid, dry one drop on paper or clean ceramic surface. A bigger sample can cause a stronger reaction. You need a new sample for each test.
ADD ONE* DROP (OR PILE) OF REAGENT
Shake bottles hard before use, then tap firmly to shake down any reagent stuck in cap. Do not let a bottle touch sample or you will ruin the rest of the reagent. Use just enough reagent to cover a sample. If using crystals avoid air pockets by flattening crystals onto sample using a clean tool. *Do not mix reagents except for „A” and „B” bottles.
OBSERVE FOR UP TO 3 MINUTES*
Disregard any color change after 3 minutes. Do not overinterpret your results, consider that color change reaction is always fastest and most vivid in the part where biggest surface of reagent touches sample, compared to its edges. Over time reaction will degrade due to air contact. Take photos. *If testing a blotter or gel tab using Ehrlich or Hofmann observe reaction for up to 60 minutes.
COMPARE RESULTS
Compare color change with instructions. Reagents can indicate PRESENCE, but not QUANTITY. Adulterants can be detected with reagents only if they cause a darker color change than the expected substance. To detect all ingredients and estimate their amount pair reagents with a TLC purity test kit.
Clean used reagent tools / testing surface with lots of running water and detergent, avoid contamination.

Drug testing kits contain toxic and/or corrosive chemicals, strong enough to burn skin and clothing. Keep out of eyes and mouth. Keep away from children and animals. Always use in a well-ventilated area. Wear gloves (supplied) when handling the bottle and cap. Wear protective eyewear. Never point towards face etc. If you get some on you/clothing, then immediately wash with lots of soap and water. Dispose of any unwanted reagent with running water, ventilate. Store reagents standing up and away from heat in a cool, dark place. The average shelf life of 2 years can be significantly extended by storing in a fridge or freezer (warm up to room temperature before use).
Reagents deteriorate with time or due to contact with air, especially if exposed to sunlight or not refrigerated. If you are uncertain whether the reagent will work, test it with an already confirmed sample.

Use fentanyl test strips (a fentanyl test kit)
METHOD 1
If testing a pill, crush one in a plastic baggie and dump out the powder. Then add 10 drops of water into the baggie and mix well. Dip the test strip no higher than the thick line. Wait 15 seconds. Put the strip away and check in 5 minutes.
METHOD 2
Mix 100 mg of sample in 200 ml of water. Dip the test strip no higher than the thick line. Wait 15 seconds. Put the strip away and check in 5 minutes.
COMPARE RESULTS
1 line = fentanyl, 2 lines = no fentanyl. Faint lines also count. Ignore fentanyl tester results after 5 minutes.
To detect all ingredients and estimate their amount pair reagents with a TLC purity test kit.
-
Pair reagent test kit with a TLC purity test kit and fent strips. TLC allows you to discover full number of ingredients and estimate their amount, however still requires reagent tests to identify detected compounds. To detect even trace amounts of fentanyl use fent strips.
Primary TLC Testing Liquid – alkaloids, caffeine, phenetylamines (amphetamine, MDMA, 2C-B, etc.), indolamines (LSD, DMT, etc.), ketamine, tryptamines, opiates and more. Included in TLC kits for amphetamine, methamphetamine, ketamine, MDMA and Full.

The kit works as promised. Everything arrived well and timely.
The Crystal reagents can be a little tricky to apply and the color reference sheet is so unbelievably confusing at first, but after a few minutes everything could be understood.
Thank you for supplying consumers with the ability to test their substances and giving them ease of mind and physical and mental safety ????

[REWARDED REVIEW] Perfect kit, and very good costumerservice. First a lot of help to determain wich reagents would be best and then gave a second opinion about the first test I did because I wasn’t sure. Can not reccommend this place enough!
And the container it comes in with the absobent also make for a perfect storage medium.

5 reagents for a very low price! I took Marquis, Mandelin, Mecke, Liebermann, Zimmermann.
Everything is perfect, and in a jar filled with pellets against humidity. An email is sent explaining how to store it. The use is simple and the notebooks with the colors are easy to understand.
Unfortunately, the spatula and gloves were missing. The response time by email is long (several days).
I recommend this kit to anyone wanting to reduce the risks of consumption cheaper

Chyba najbardziej praktyczna opcja, bo samemu dobierasz to ile i jakie odczynniki chcesz. Dodatkowo jest ich taka ilość, że starczy na długo nawet przy częstym testowaniu substancji, bardziej się opłaca niż pojedyncze testy. Zestawy zawierają wszystko co potrzebne do testu, są łatwe w użytkowaniu, a wszystkie instrukcje na stronie, wiec przy przestrzeganiu ich krok po kroku nie ma szans, że ktoś sobie nie poradzi ????

Wielka zaleta- można wybrać testy które nas interesują. Można uzupełnić zużyte lub popsute testy. Całość wychodzi taniej niż w przypadku zamówienia całych zestawów. Zapakowane dyskretnie- zgodnie z prośbą. Zamówiłem Hoffmana, Ehrlicha, Mecke, Marquisa i Robadobe. Wszystkie działają, a przechowywane w zamrażarce nie psują się.

W 100% warte swojej ceny. Zdrowie jest najważniejsze, a zestaw ten pozwala zabezpieczyć się przed wstąpnięciem na niechcianą minę. Zamówiłem go lekko ponad miesiąc temu, a nieraz już zdążyłem się przekonać o jego skuteczności. Nawet jeśli ktoś myśli, że nie musi się martwić o swoje kontakty, oferowane tu testy pozwalają mu spać jeszcze spokojniej, a wiadomo, że przezorny zawsze ubezpieczony. Dodatkowym atutem jest możliwość wyboru dowolnych odczynników tak, aby nie musieć zamawiać kilku różnych zestawów w przypadku potrzeby testowani różnych substancji. Ponadto, na ogromny plus składaja się akcesoria dodawane do odczynników – szpatułka, rękawiczki oraz porcelanowa płytka. Z nimi nie musicie się o nic martwić w przypadku przeprowadzania dowolnego testu. Zbliżając się do końca, kontakt ze sprzedawcą szybki, a paczka zapakowana w taki sposób, aby do otwarcia nie zwracała niechcianej uwagi. Dbajcie o zdrowie i wspierajcie szczytny cel!:)
