In fear of getting this thread closed, ill word this as carefully as possible... I'm a seasoned IV veteran, and normally when I mix up my powders with water, they will turn from a white or tan powder to a brownish liquid of varying darkness. Recently, I've been getting some powder that turns the liquid black. Has anyone seen this before? I am not asking to describe u cut, as I just got my last thread closed because I did.... In ten years of off and on use, sourced from all over the US, I've never seen such a thing. Anyone else?
