I have my last needle and syring that I used 3-4 times just to draw prop. out of amp. I did not use it to stick myself yet. Is it still safe to use on me?? I cleaned it with some alcohol, by sucking somein and pushing it out. The syringe was use just to get prop. out of amps because all I had left was very small needles for shoulder njection. Is it safe to use it on me or should I say fuck it???
