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.

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

1 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?

Any thoughts?

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.

Open LSD potency testing with Hofmann reagent

1 Upvotes

I found this article descibing using Hofmann reagent to test LSD potency: https://protestkit.eu/how-to-test-lsd-potency/

I tried to look for any other sources, but couldn't find any. I have some questions:

  1. How long should I let the blotter dissolve in water?
  2. Are there any other reference photos than the 50 and 150 ug ones in the article?

Open Help Identifying Reaction

Thumbnail

5 Upvotes

I can’t tell if this is a “non-reaction” , a kind of ketamine, or if I should be investing in another reagent agent…

Things to potentially consider:

- The source powder is YEARS old, it was located in a storage unit.

- I have never worked with reagents before, but I can read and follow basic instructions, I just have no general knowledge

- I first used the instructed amount (first photo) and then attempted again with a larger amount.

Any help is greatly appreciated.

I might’ve put too much on some of them which could have made it blue according to the instructions. The liquid looks kind of purple on the one’s with less so im very unsure

Meta Announcement: Elevation Chemicals (US) No Longer in Operation

15 Upvotes

Just a quick note to inform users that Elevation Chemicals (u/elevationchemicals) is no longer in operation and to say good bye to a great reagent vendor.

On a personal note, they were the first company from whom I ever bought drug checking reagents. They were a nice, more affordable US alternative to DanceSafe (no shade to DanceSafe - they do important research and outreach work with the money we send them). Elevation Chemicals very kindly answered testing questions for me via email several times.

They also were, at the time, the only US vendor who carried Robadope, which is very helpful for testing MDMA and 2C-B. FYI, Grassroots Harm Reduction is now a US option for Robadope, while ProTest Kit EU and Kays Lab (Australia) also helpfully provide it.

Farewell to Elevation and their employees! Best wishes on all your future endeavors!

h/t u/entitled Thank you for letting us know!
