That's pretty fucked up. Like the poster above me said, I would be very wary of IV use when it has some kind of weird cutting agent that they used. Do you know anyone else that has gotten it, and if so have they said anything about it? Is the consistency the way it should be? I'd say that it's very dangerous to inject something like that, because god knows what's in it. I know that's pretty much common sense to someone who isn't an addict anyways, but addicts tend to be very hasty when they're sick. I'd say that if anything, give it a very small sample and see how it goes, and then gradually increase from there. There's no reason why it should be that color at all, and if your dealer is just some random slob and not someone you know personally, then you probably can't trust what they say if you were to ask them what it is anyways.
Post again if you find anything else out about this because I'd be curious to know.
