So I've been injecting Bupe for years now, but when I hit an artery it doesn't burn like it did with Heroin, if at all. I've recently started adding Diphenhydramine to my shots so that I can feel if I'm in an artery and pull out right away. Does anybody know why this is though? I have hit a good handful of arteries in the years I've been injecting Bupe, but no complications from any of them. I do filter the fuck out of my shots though. They go through 2 coffee filters, and 2 cottons. I'm wondering if it doesn't burn because they are filtered to the point that they just look like slightly colored water.
I don't know though.
Edit*
I'm also wondering if it's because Bupe is less caustic than Heroin?
