Last week in Melbourne, first time I had ICE, or anything in about 8 mths, I had some that was gold-black. about 30% (mostly the larger crystals) was pretty much completely black. The rest was yellow-gold, and not just slightly tinted but really dark.
I injected it, mixed up to a gold solution, took a long time to mix up (disolve - tho pretty chilled water) as well, was very strong and very rushy. Didn't last for too long. I dunno what I'd say about it, very sketchy-scatty kind of high. Definately a strong product, but very rushy/tingely in the head, strong, but definately not clean.
my friend smoked it, interestingly, whilst the felt pretty intense rushes, it didn't burn very long. It burnt clean, and tasted ok, not great, but didn't last long in the pipe at all.
I've had stuff like this before, long ago in the past, always been pretty similar. If you see it, I'd say grab it, it will definately get you going. But its not the cleanest of highest. Left both of us pretty loopy the next day...
