i ve not got pics. but my uk sourced tan powder turned the marquis dark purple then almost black in about a minute.
@swedger77 Hmm that normally indicates BZP turning to black very quickly, as BZP was used in alot of extacy pills due to it haveing the same marquis reagent outcome although 6-apb i believe turns to purple over a longer period of time
