i used to hate them because of hitting a newrve once, but just started them because of an ED cycle. They go in smooth as I have no scar tissue there and there is little to no blood. However I am sore for days. At the same time I always thought glute shots were harmless and hit what i think was a nerve yesterday. It hurt all the way up my right side for about 5 minutes. Bled like crazy and def sucked. I do delts, glutes, and quads for ed injects because they are 2cc each. If its just one I cut out legs and go with pecs.
