While on holidays I will be needing one last shot of Sust. The idea is to simply get a sostenon preloaded 1 cc syringe while on holidays and administer it...but the problem is the pins on those are .5inch. I am currently using glute shots with a 1.5 incher. I went back to my reading and it seems the shoulder is optimum for this length of pin ,however I read of a high probability of soreness in the shoulder....not cool on holidays or really anytime...and since my glute shots are trouble free I am wondering if anyone has used .5er's for their glutes?
