I followed the instructions given in a my previous post and watched a few videos on bicep injections. I didn't rest my forearms though, that might be the problem. I didn't flex the muscle, it was loose and wabbly for the shot. I aspirated and pressed the oil in slowly. They aren't unbarable, infact I trained chest, bis, & tris yesterday; my arms feels so strong it's unreal. The next shots will be in my quads, that's another untapped muscle. I have always put shots in my glutes.
