OK I've been doing ED injects and mixing it up between my glutes and my quads but I never really feel comfortable picking a spot to shoot in my quad. What are the guidelines for Quad injects? I'm hitting the side about 5 inches above my knee... can anyone give me some guidelines to follow? and where to stay away from... I like quad injects so much better than glutes because I have better control and I can see what I'm doing
