Melbourne MDMA not as good as the past

I got hold of some MDMA rock, tested it and it was a little slow to react, In fact it doesnt seem anywere near as good as the Brown MDMA that I was getting a few months ago, what does everyone think about the quality of the MDMA around?? Anyone who sampled the brown MD and current white MD your thoughts appreciated.
Thanks

the stuff we have been getting is more of a grey rock or a brown sludge that resembles a soggy bar of soap, and i must say that the grey stuff is the best i've fuckin had. MMMMMMMMMMMMMMMMDDDDDDDDDDDDDDDDDMMMMMMMMMMMMMMMMAAAAAAAAAAAAAAA, it gives a new meaning to tnhe golden arches.
