im still fairly new to im injections....about 10 weeks now 100 mg of prop eod. besides the first week of a little soarness i hit the same area on the upper left part of my left glut. ive experienced no pain at all since the first week....i know this may sound sick, but i love injection days! i get a little rush after i pull the pin out! im using quality prop......first 9 weeks i used body research testolic and now im using brittish dragon prop. most of my buds use qv shit. and i really think thats what it is SHIT!!!!!!! the all complain of pain from the prop or the test 400 and some of them get real sick....i will never use that crap...its garbage IMO!!!!!!!!!!!
