Ive been curious, because Ive picked up my 22 gauge 1 inch pins at a local Farm & Tractor Supply. From what ive read and heard my issues with soreness, and seeming to just get a buildup in the injection area seems to be from not using a long enough needle, so it was suggested I try a 1 1/2 needle. Locally I cant find any of course, and when I google it, I seem to get alot of foreign sites, where do you guys like to buy your pins?
