Currently on 100mgs prop ED, 250 Test E E3D, & 1cc B-12 daily (1st cycle, 23, established workout routine). Even though Im in some god awful pain, I've gotten use to it. Today was my day of all three. Last time, I used a 1.5" 25 g (filled all 3 cc's) with no major problems. Today, I had to use a 22g. It hurt like I don't know what. Immediately, I felt swelling around the opening, and now I have a bruise with a knot about 3" long by .5" wide. I will do my own research, but can I contribute to the 22g, or what? Thanks
