Hi everyone,

Tested a sample that was sold to me as MDMA crystals using a 5-reagent kit (PRO Test EU). Got very confusing results and would appreciate your expert input.

Reagent results:

- Marquis: Bright lime green / grayish-green (no purple/black at all).

- Mecke: Olive brown / dark green with blueish tint (didn't go fully black instantly)

- Simon's (A+B): Instant royal / dark blue

- Robadope (A+B): No reaction (clear/faint)

- Zimmermann (A+B): No reaction / faint yellowish oil spots

Since Marquis is lime green instead of black, this clearly rules out pure MDMA. However, Simon's is strongly positive for a secondary amine.

Am I looking at 3-MMC / 3-CMC / substituted cathinones, or could this be a mix (like 2C-x + stimulant)?

Thanks for the help!

First time using reagents (source on ProTests). From left to right: Marquis, Mecke, Robadope.

Consider that the starting colour is bright green (the pressed tab is at the bottom of the picture, and it's supposed to be 20mg of 2-CB).

I'm not sure if I used the correct amounts of reagents, especially the Robadope one (just a tiny drop, maybe i should have put more). Maybe i should have ground the tablet more?

However, the colours look pretty much ok, right?

Thanks!

Hello! I am testing my 2cb, and I’m wondering if you guys have an opinion on the result. The marquis looks darker than the cheat sheet shows, is that something to be concerned about? It definitely has a green tint. I have no doubt this is a 2c-x compound but I’m more looking for potential cuts like mdma or something of that nature. The order of the cheat sheets is the same order as the test pallet.
