From what I understand when I'm on cycle and working out steroids should get to all muscles which most people think of as biceps, pecks, quads, etc. Have any of you wondered or found out any research on affects on muscles that arent so easily visible. To be more specific we all have muscles within out bodies, heart, sphincters, intestines(or even the tongue)....do these becomes enlarged, stronger, tighter? Any info would be great, and of course this is just out of my own curiosity.
