Just curious as too what you guys think the best spot to inject is....I'm currently running Test in my butt but I want to shoot in my shoulder, its much easier and quicker for me. Is that okay or is there more pain in the shoulder? Also, do you have to use a different size syringe for your shoulder...currently I'm using a 22g/1.5" syringe....can I do a smaller guage? Thanks guys!
