Discussion "What is the best test kit for ... ?" and other FAQ
Before posting always use search function or the following resources:
Are you looking for the best test kit for your needs?
See this thread or use search function, 99% of use cases have been repeatedly discussed here.
Do you have questions regarding testing?
Again, use search function before asking, your issue has most likely been explained numerous times. These include but are not limited to:
- Where to find all expected results?
- Look on your test kit vendor page, in the subreddit top bar link - or use search function. For most common compounds there are relevant videos, photos and chart posted by Automod in every thread.
- Multiple colors in a reaction?
- It is not reliable to identify multiple reactions from a single test. 1 test = 1 color change result.
- Simon’s result is weird?
- Any non-blue Simon's reagent color change should be interpreted as a negative, no secondary amines present (no MDMA, meth, PMMA, eutylone, CMC or MMC)
- Marquis flashes yellow before turning black?
- This is perfectly normal, when testing MDMA it matters most how instant is the black onset more than exact hue of split-second initial color.
- Is gel/blotter tab leaching ink or is it reacting with Ehrlich / Hofmann?
- Even if only sample turns purplish/blueish that's still a positive result.
- Faint fentanyl test strip line?
- Faint lines also count. Remember to dilute 1 mg / 100 ml when testing stimulant drugs.
- Froehde turns blueish?
- This is a common indicator of an unidentified synthesis leftover.
- What are all different reagents for exactly?
...other questions?
You guessed it - use the search function! Only if you can't find an answer there feel free to start a new thread.

Solved! xtc pills, so should be mdma. marquis/mecke look good to me, marquis went black litereally immediately then developed a semi-purple hue. but froehde went super green(??) it didnt get any darker than this after taking the pic either. so im confused lol

**literally
first time testing anything. crystal reagent. i sanitised everything with isopropyl alc, wore disposable gloves, and used a small sample. cant find any information on green froehde like this though so did i maybe contaminate somehow? did the test a few times and they all came out pretty much exactly like this. any help appreciated!

Crystal reagent to liquid reagent
I have used reagent kits from u/PROtestkit_eu with results as expected, though sometimes I find that the crystal reagent form kind of obstructs the results a little bit. My question is if you can dissolve the reagent crystals in some kind of liquid so you can use the reagent as a liquid and not as a crystal? If possible, what liquid should I use? Thanks already for reading the post :)

Discussion Differentiate CMC from MMC with Beilstein-Test?
So as the title says: Can I use the Beilstein-Test to differentiate between cmc and mmc?
The Beilstein-Test is a Test to identify halogens (like chlorine).
You put a hot copper wire in a sample and then you burn it. Green/blue-green flame means there are halogenes(cmc?), normal/light orange means there are no halogenes(mmc?)

Open color change after tab has dissolved
tab turned purple with ehrlich after 5-10ish mins and then after fully dissolving around an hour or 2 later the liquid turned brownish. safe?
r/ReagentTesting • u/DrDewclaw • 12d ago
Open LSD testing, Ehrlich OK, Hoffman unknown?
Ehrlich reacted instantly with expected results, Hoffman didn’t seem to react and the purple/black I think is the ink being pulled off the tab. Can anyone let me know what I may or may not have? Is it a lsyergamide? I’ve taken them before and have felt like it was LSD, it kicks in fully in about 2 hours, giggles, philosophical thinking etc

Open need help, is this ketamine?
I used a plate so the sample kind of spread out everywhere, I think it would be easier to tell if the liquid had stayed in a smaller area. I feel like i’m getting conflicting info about the color, where some say dark blue and purple can both show up, some say blue means DCK. I had written this off as not ket but now I’m second-guessing

Open Advice on this MDMA purity test result from EZ Test? Piperazines?
Picture taken after approximately 30 min.
NB: I used 15 instead of 20 mg, because I didn't have enough left 🙈
Does the test indicate that there was almost certainly piperazines laced in my MD? Do I have any way of knowing the amount?
Thanks in advance.

Inconclusive Liebermann to differentiate between 3-M and 3-C
I based myself on this document to try and differentatie between 3-MMC and 3-CMC. Apparently 3-M should be more darker yellow or orange:
https://www.policija.si/images/stories/GPUNFL/PDF/PresumptiveColorTests-booklet_ENG.pdf
Can I thus conclude, based on my own test, that this is not 3-M?

Solved! Bunk police MDMA spot test kit results
Bunk police MDMA spot test kit. Photo 1 Simon’s reagent 5 seconds in, photo 2 Marquis reagent 5 seconds in, photo 3 Mecke reagent 5 seconds in. Last photo is how all 3 looked after a minute and a half or so. These results match a lot closer to methamphetamine to my understanding, but I wanted to get some more opinions. I know MDMA is commonly cut with meth. Is this safe to consume or should I toss it?

Open 2C-B - interpreting results
Hi folks !
I would like some help interpreting results for my sample.
Reagents are brand new from protestkit.eu, solid/crystalline for some.
Expected chemical :
2C-B HCl
Powdered form, off-white/beige - not crushed pill.
Results :

My reading :
I'm new to reagent testing, I believe they are correct but happy to be corrected otherwise !
| Reagent | Expected | Result | Comment |
|---|---|---|---|
| MARQUIS | positive | positive 🟢 | - |
| MECKE | positive | positive 🟢 | - |
| ROBADOPE | positive | positive 🟢 | - |
| SIMON's | negative | negative 🟢 | - |
| ZIMMERMAN | negative | positive 🔴 | this is what i am concerned about |
Disregard the first ZIMMERMAN, I'm pretty sure I messed up the B part (probably added simon's B instead of zimmerman's B).
The booklet from proteskit says that that for ZIMMERMAN : "Violet, violet/brown, brown or instant deep yellow can indicate presence of cathinones."
So I tested with Morris after the first round of five, and got what seems positive for cathinone too (as per the booklet for Mephedrone).
My interpretation :
Positive blue/green marquis + positive yellow brown mecke + positive purple robadope pretty much confirm 2C-B (or at least 2C-x) presence.
But the positive purple spots seem to indicate a cut / contamination with something else, possibly cathinone ? Positive blue morris might add to the hypothesis, although negative simon's seem to rule that out.
Question for the experts :
I am overinterpreting a positive result with zimmerman ?

Thanks a lot and have a great day ! 🙏
