Curious as to what location folks like to use for injection sites? I had always used my quads as it was easy to access and I just seemed to handle the shots better. A while back my HRT Docs assistant told me to not use my quads any more as the body stores more bacteria in the larger muscles? Or something to that effect. He told me to use my shoulders. So I started. But to be honest I miss shooting in my quads as getting that perfect downward angle and spot in my shoulders can be a bitch at times. So..where do you prefer to inject and why?
