I had a workout partner that reuses his pins. He'll buy a ton of gear but only a few pins....the dumbass will use the same pin over and over (cleaning it of course in alcohol) until it becomes dull as shit. About halfway through every cycle he gets sick or he gets infected injection sites but the guy just doesn't learn. But then again, this is the same guy that doesn't believe in post cycle recovery products...."fuck it, man, I'd rather use that money for more sauce"....dumbass....
