velofel and yo nuclear domain it's the nucleus and however much volume around it it can effectively regions of the body might be differentially sensitive to a variety of external stimuli so for example the you know different muscles in your body have different numbers of densities of androgen receptors for example for testosterone so you know more receptors you have the more we respond to any given amount and I think it's been shown at least once that you know that the trapezius muscles the traps might have velofel za higher density Vangie receptors but that's not there's many no means cleaner than this uniform throughout all human populations so you know for example if you take a certain amount of to say okay I'm just gonna get as big as possible here we go you know your traps for example might have a higher antigen density or your legs if your top flats perhaps and they respond really well toward as whereas other muscles seem to not respond nearly as well and still others may seem to
