MDMA or not??

[bakedbeans1]

right hi people. time ago got sum stuff sold to me as mdma crystal. it werent actually ur standard crystal, but looked more like a light brown rock, and when crushin it up had tecture more like toffee. well only jus got my testin kit thru today, and bein a lil bit inquisitive i tested it. well it definitly werent mdizzle. no purple/black colour. it bubbled a lil bit and remained a sorta clear colour, with a very very slight hint of purple. jus wonderin what it is. do piperazines come in crystal form?
i tried it before i had the testin kit, had about 0.3 g. had like no effect except for a dodgy stomach ache and the shits lol, and slight amphetamine sorta effects, ya know bein a bit more awake like.
anyway anyone have a idea on what this could be? jus interested like cos it def aint md.
safe

I have no idea if piperazines come in crystal form, but it really wouldn't surprise me if they did, or some asshat chemist has figured out a way to do it to pass it off as molly shard. I am curious about the slight hint of purple though in the Marquis....maybe someone screwed up a batch of what they thought would be good molly? Sad.
