I use alcohol swabs and 2 sterile pins... 1 for drawing and 1 for injecting. I even swab the top of the vial before I draw from it. After all of that I got a cellulitis infection in my arm just this week. Swelling from my deltoid all the way down past my elbow with inflammation and chills that shook my body.

After a trip to the ER I was given keflex and yesterday I had a golf ball sized hematoma drained at my second trip to the ER. The blood was normal looking thank God but I'm pretty damn careful and this shit still happened to me.

Bottom line for all the guys out there, play it as safe as possible. Get alcohol swabs that are at LEAST 70% isopropyl alcohol. They sell them at any drug store/pharmacy.
