methylone hydrochloride

I have crystallized the bk-MDMA crystals, then I have recrystallized it with dionized water (to make it purer) and it still has a brown color (I guess due to impurities) and the crystals smell like methylamine, my goal is for the crystals to be transparent in color .

I want to start selling methylone that I synthesized myself on the European market, but I don't know the prices I should set. Thank you!!

If my 2 different batches of methylone have this color after recrysatlization of the methylone HCl, how can I make the crystals transparent in color, I think they look like this because of the impurities, (the white powder photo is the hydrochloride of methylone) before recrystallization.

I have just synthesized bk-MDMA (methylone) and I would like to know if any expert could tell me if the anti-drug test comes out positive for said drug? Thank you all!! ;)

I have tested the supposed methylone hydrochloride that I have just synthesized with the help of an anti-drug test from the brand (EZTEST) but I cannot appreciate the colors well, so I don't know if it tested positive for methylone. Thank you all!

Thank you!! ;)
