So you have a friend that wants to start juicing. Ya walk him through the sites to get the most knowledge and to read up on the how to and how not to.... Help him plan his cycle and hook him up with his gear. Ya do all the "work" for him. And he starts pinning. Only you forgot to tell him to be sanitary......???? Yeah, this happened to me. My good bro comes to me complaining about his last pin turning colors, a bit sore to the touch and bruised looking. I honestly didn't think it was necessary to tell him to use alcohol before and after. I also asked did he wobble when pinning. He is using 25guage pins. I asked did he take his time or did he just shove it in...... Yep sure did. Power wash effect! When I asked if he had been doing any of this he answered with a ????? Noooo.... As if he had no idea that he should. Guys you can never be too thorough when ya helping someone out. Don't just assume that you buddy knows something so simple as the be clean when pinning. Just because you know and thinks its common sense doesn't mean someone else will think to do that. My buddy bought this lesson the hard way. Be thorough guys!
