I cannot seem to find any IM syringes/needles to purchase in US online? What is the deal? The smallest I can find are 25g x 1 1/2. I know when I was doing the clinic they were 27g or 28g x 1 1/2. I know to do that you have to buy the needles seperate but I can't find the needles in 27 or 28 g -- don't want to put a tree trunk in my leg! Any ideas? I have enough sub-q syringes to last a couple of rounds but would like to do IM like my first round. If it is any help I live in AZ.
