Discussion "What is the best test kit for ... ?" and other FAQ

2 Upvotes

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?
    • See comparions chart here or more up to date in Questions section here.

...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.

Open Ehrlich turning dark red in tube, but pinkish on plate: LSD

First test was done in the tube, came out dark red. No change

Second test was done on a plate, came out a lot more pinkish. But then turned dark red after a while. Idk if this is just because it was more space to spread out and not as concentrated as the tube.

Black gel tab

Thoughts?

Discussion Do urine test strips also work as normal test strips?

I want to test some pregabalin but all I can find online are urine test strips. Can I use a urine test and test it by mixing the substance with water before taking it?

Open awfully cut Aus cocaine. Weirdest test I’ve gotten. What would cause this oily pearly sheen on the surface of these two tests?

Post image
2 Upvotes

The morris reaction is common when full of filler, while blue it just stays undissolved. But the way the particles looked stuck out as really strange to me.

Lieberman immediately started fizzing into an orange but then faded to a more pale yellow.

Marquis, started fizzing and turned into a deep orange. Then settled into an almost pale brown.

Robadope in my opinion was positive, i took the pic early, I did a side by side and it was definitely reacting, just a much deeper muted pink.

Simons was negative, but the sheen is so weird.

What do you guys think?

This bag, I did a bit from and then never touched again months ago, because it was so shit.
from what I remember it had practically no taste or numbing. The first line I felt pretty dissociated. I was using it to keep me up, reposing constantly, and it didn’t feel like it was doing anything at all except making me slowly feel more and more shit.

I put the regent colours into protest, it suggests amphetamines and maybe diphenidine/mescaline. So weird. I don’t know, what do you guys think?

Open Confusion with Q Test results (because it passed the reagent tests): No LSD detected

Post image
4 Upvotes

I got some tabs recently of what is supposed to be LSD or a close analogue.

I reagent tested samples from multiple tabs, and they passed
(pink-violet with Ehrlich and deep blueish purple with Hofmann).

However,
using the Q test (I very carefully did it as properly and accurately as possible),

the result is clear with no color reaction, meaning basically 0 micrograms of LSD.

My confusion comes from the fact that they passed both of the reagent tests.

Does anyone have any idea what this could mean?
Another analogue similar to LSD enough to pass the reagents but not react to the Q test?

the person who dropped the liquid missed parts of it?

Looking at bottom two left to right is Simon’s then marquis next two it. middle row far right is marquis from another batch of mdma. im a little hesitant cause marquis is not super dark

Discussion Mandelin for testing MDMA for PMA?

1 Upvotes

The description on the BunkPolice website says that the Mandelin spot test kit is a follow up for cocaine and Ketamine. I just want to confirm whether this can also be used to test MDMA for PMA. I already have the test kit with Marquis, Mecke and Simon's, but I keep seeing things about PMA being added, so just want to be extra sure.

Discussion I am a little confused about the different tests for lsd

1 Upvotes

I am new to this and I think I kinda understand what the different tests do, but I am not sure which one to get. I saw that ehrlich and Hofmann are recommended to use together for a better result. But if Hofmann can go one step further in telling you what kind of drug is in the sample, why do I need to use Ehrlich? Also, can I just do the lsd potency test? I just think that is more straightforward. Am I missing something?

Discussion Is it possible to identify meth in an mdma sample?

2 Upvotes

Pretty much the subject.

Is it possible to test the presence of meth in a sample of mdma using reagents? Had a sample that tested for mdma using marquis, froedhe, and simons but gcms also showed meth.

Pretty much the headline. Testkit app says that it could be 25C-NBOme, Testosterone or Dimethylpentylone, but nothing seems to be a 100% match. Ideas?

-Second pic is ~5min later with added reagends

-In the first pic the Zimmerman glows blue due to the flash of my phone. In reality it did not react at all.

Discussion Protestkit eu in the uk and its deal with reagent test uk

2 Upvotes

So if I were to order the mdma test kit on protestkit would I receive all of the reagent test kits advertised but some would be made and delivered by reagent test uk, or would I just not get some of them and be forced to pay extra on top of already paying more for less? I find it incredibly hard to believe that we are in a time where people are having the same shady business moves as ea and Ubisoft for safe drug testing, essentially having to pay double the money plus shipping just to get the same amount, this is beyond deplorable if it’s the latter, also what is the deal that they agreed on?

Got some gear off a questionable source, not sure what these results mean I cant match it up. The liebermann has calmed down to a yellowy-amber/brown after 10 minutes but not sure if its just a normal reaction?

Supposedly mesculine but came in a tiny pill form, highly dubious that it is what was advertised as.

Purchased some cocaine & gave it 2 tests.

Purity Test: Seems like it is reading high purity/very high..? Maybe?

Any thoughts?

Apologies for the terrible pictures/lighting I wasn’t in a well lit area.

After about 8 minutes I began to see a little brown but not 100% sure. Doesn’t orange to brown-ish or dark brown suggest fentanyl, meth or amphetamine in the coke? It stayed this color. No change after hours.
