In short, I believe that someone is selling Methylone in bulk and cutting with an agent that gives a black-ish test on Marquis. Probably someone packing caps for festival season (personal speculation).
I am confident that this compound is Methylone. I have discussed at length with the vendor I used, Owlcity on Alphabay (awesome vendo, great communication), and the aesthetic/smell is perfect. The powder is cakey and fine, with the distinctive Methylone smell, just like it came pre-ban from Chinese labs. I know and love this molecule, but I believe it is being cut with either Asprin, sugar, or a miniscule amount of MDxx to give the desired reagent test.
Does anyone have any insight into this? Am I being stupid? Anyone aware of highly active cuts that might yield THIS reagent result?
Top to bottom: Marquis, Mecke, Folin, Mandelin. Note the greenish Marquis, the reddish tint to Mecke and yellow greenish tint to Mandelin. Folin is consistent with MDMDA.
How old are your test kits?
Thanks for lookin out. I hope someone hasn't discovered something cheap to cut with.
