Does it matter where you inject? What I mean by this is if for example you inject in your bicep, does it only have an effect in that area or does it work on your whole body. Similarly if you were to inject in your calf, would it only work on your legs? Or do injections work like pills? Probably going to think I'm a retard but just really want to nail down on all there is to know about steroids before I dive into use.
