Was that an Australian batch ? - if so I know what your talking about.
I also happen to be in posession of that batch (have not tried) however I had previous got black MDMA before, looked like quartz crystals just black.
But from what i've read the black MDMA has always been good MDMA so time will tell.
Back around 2010 or so, I did get some other dark/black mdma from belgium (same location as this MDMA is from pupossedly) so I don't know if there doing a specific synth or precursor to cause the black MDMA or whether it's not fully washed / impurities.
I remember back then, it wasen't super strong so that batch was likely impure, but this batch has been tested at 87%.
Does anyone know why MDMA would be black ? - for instance does anyone know a synth route to cause this perhaps from an unusual precursor ?
Last batch of black MDMA:
