Reagent test results: suspected mescaline vs. known reference. Need a second opinion.

Hi everyone,

I was offered a powder sold to me as mescaline. Since real mescaline is fairly rare, I wanted to verify it with reagent tests before doing anything else. To have a baseline, I ran the same tests on a sample of mescaline I know to be genuine.

Here is the layout of the main photo:

•	Top row = the unknown sample (“mescaline”)  
•	Bottom row = the known, genuine mescaline (reference)  
•	Left to right in both rows: Marquis, Mecke, Froehde

One thing that already made me cautious: the seller recommended starting the unknown sample at 100 mg. In my own experience, mescaline needs roughly 300 to 400 mg for a full experience, so a suggested starting dose that low feels off to me. To my mind that is a possible red flag that this might not actually be mescaline but something considerably more potent (for example a 2C-x or DOx compound), where 100 mg would be a very different and potentially dangerous proposition.

I also ran a second test using Simon’s reagent on both samples. Result: both came out dark grey, with no blue coloration. My understanding is that Simon’s reacts with secondary amines (turning blue), and that mescaline as a primary amine should be Simon’s negative. So the absence of blue is at least consistent with mescaline and argues against a secondary amine like MDMA in both samples. The fact that the unknown behaves the same as my known reference here is somewhat reassuring. That said, I do not think it rules out a more potent primary amine compound, which would still fit the unusually low 100 mg recommendation.

A few specific things I am wondering about:

•	Do the color reactions of the unknown sample match the reference closely enough, or are there differences in hue, intensity or how fast the color developed?  
•	Is dark grey (rather than colorless or pale) a normal Simon’s result for genuine mescaline in your experience?  
•	Given the low recommended dose, does anything in the unknown row point toward a more potent compound rather than mescaline?  
•	Does the combined picture (Marquis, Mecke, Froehde, Simon’s plus the 100 mg dose recommendation) change your read at all?

I am aware that reagent tests only indicate substance classes and say nothing about purity, dose or adulterants, so I am treating this as one data point, not a final answer. Given the dosing mismatch, I am inclined to get lab based drug checking before considering anything else, and I am open to that route.

Photos attached. Thanks a lot for taking a look.
