Hi all. I'm thinking of trying shooting speed...(not Ice or Meth, just regular amphetamine sulphate). I have NO experience w/needles so I really need some help...(I dont wanna end up with no arm like Harry in Requiem 4aD eh?) so any advice would be appreciated... If I'm currently taking 2-3 points per day (snorting or swallowing) how much should I inject? Also is it safe to do it alone? I don't know anyone else who uses needles and I'm pretty nervous... Thanks.
