On the basis of the research you have presented, what you are assuming here is not good. Human physiology and rat physiology differs substantially in ways too numerous to name. For this topic to be of any use to us, the studies must be performed in humans and submitted preferrably to a peer reviewed journal. Although I do not remember the reference off of the top of my head, a number of members here are familiar with a certain journal article that details the up regulation of androgen receptors in the presence of large(r) doses of anabolic steroids. Over the course of a six month period, however, the quantity of androgen receptors falls to baseline. This is a good example of why it is important stick with human studies when dealing with this topic of interest.
