I would like to know the answer to your question.
In addition (and related to Androgen receptors), I would also like to have some more information/discussion on the other side of the ledger regarding testosterone.
As I see it gaining the benefits of testosterone could be attempted two ways. Firstly the supply side of the equation, either providing/encouraging more exogenous or endogenous testosterone (for example taking testosterone or Alpha Male to increase test levels)
Secondly, the use side of the equation, making better use of the testosterone that is available. This side is rarely discussed in detail from what I have seen.
For example, do weight trainers have lower testosterone because they have better uptake of testosterone at receptor sites? Does the efficiency of that uptake increase? How? By what methods?
Related then to your initial question, what means are available to 'get the most' out of your available testosterone? Clearing out your receptor sites or increasing the number of receptor sites would be ways I would imagine.
If anyone can shed light on this it would be interesting.
