I'm a bit confused as to where/how to do my quad injection. On the spotinjections that guys quad goes down lower than mine. In his leg his quads dominate while mine are the exact opposite, my hams dominate my legs. He's shooting it from the side is it bad to shoot straight down? I saw a pic posted by Terinox a while ago about where to do it and it looked different than spotinjections. Any help would be much appreciated as the needle is in my hand waiting impatiently
