Ok, so I don't guess I gave enough info....sorry. I'm fairly new to this whole Bluelight thing. I'm an IV'er of meth. The more diluted it is, the less rush I feel. In fact sometimes I won't get one at all due to the fact that my shot was 20% dope and 80% blood and water. I guess I'm asking if there is any way you could get the blood out, or at least some of it? I've only been shooting for a few weeks and I've read alot of HR info, but nothing on this topic. I would not save it, just use it right away. Saving it would mean risking the chance for bacteria to grow. And sometimes I also start getting clots and chunks in there. How do I get rid of those as well? Plz help =) I'm sure I'm not the only newbie to shooting that has this question. Oh, and as far as filtering it back through the cotton once there is blood in it........how big should the cotton be? What is this process accomplishing? I have done this before but saw no different in the before shot and the after shot.
