I thought that I would share this trick for those of you who dont know it, I had to use it tonight. What happened is I was doing my shot and wanted to shoot my shoulder but opend my box of needles and realized I was all out of 1" needles. So what I did was I took an 1.5" needle and took the cap off. Then i measured down one inch from the end of the cap and cut the end off. Then I put the back on. Now I have a 1" needle I can use to do my delt.
