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 combine reagents except for „A” and „B” bottles.
OBSERVE FOR UP TO 2 MINUTES*
Disregard any color change after 2 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.

Great collection of regents that provides a very broad number of results, but why, please tell me, why would you go with crystalline base for the most useful ones, the reaction is very faint , it is leaking everywhere because the bottlecaps get clogged by small crystalline bits making them difficult to seal, it also really messy to handle, and to get the right amount out of the tiny hole.
I will have to get a replacement set of erlich froehde mecke marquise and Liebermann in liquid form, apart from that, the rest of the kit is good

huge satisfaction. My friends and I have already tested several substances and thanks to this we have found out which suppliers are trustworthy and which are not. I immediately bought a second set which is located in the pub where we normally meet (the staff is very helpful and wants to do a test once in a while for safekeeping) so that I don’t have to carry it with me all the time.
I thank the entire Protest team for this set and I wish them a lot of success. You are doing a very useful and invaluable job. I wish you a lot of success. Whenever someone asks me for a test I will send them to you immediately.
In short:
Test: 5/5
Shipping: 5/5 (Czech Republic 2 days)
Functionality: 5/5
Price: 5/5
The Protest team and their perfect idea and their determination to continue: 5/5
Total 20/5!
If you are still hesitating whether it is worth it and whether it is worth it at all, remember that you only need a very small amount and you can have long-term consequences.
Don’t take chances with absences!
It’s always better to test it!

Top Preis Leistung
Für den Preis macht man hiermit nichts falsch, Handhabung auch mega einfach.
Sollte zum Equipment jedes Forschers gehören finde ich.

Easy to use without a doubt.
When first getting a test kit i thought that it would be complicated and need some practice before knowing how to use it. However this was not the case. Right after receiving it instructions were clear as day.
1. Look up the substance on this website in the results section.
2. Pick out the reagents which correspond to the substance you wish to test.
3. Test the substance. (There are even some videos showing you how its done)
Its really simple, and makes use of substances way more safe as you have to know what goes into your body. Otherwise you would be betting your life in exchange for a high.
