ok
. thanx lol . well , one explanation is testosterone is increasing igf-1 levels in the body , localised igf-1 as well as liver derived .. this igf-1 would obviously activate satellite cells , which is a very important phenomenon by itself .
When satellite cells are prohibited from donating new nuclei, overloaded muscle will not grow (Rosenblatt,1992 & 1994; Phelan,1997).
supraphysiological levels of testosterone give rise to increased numbers of myonuclei and thereby an increase in the number of total androgen receptors per muscle fiber.
ofcourse , as given in the article , increases in strength etc would mean heavier loads are used , better muscle contractions etc which itself increase AR count .
ofcourse , a high dose is relative to the person's size ... so no need to keep increasing doses , like haycock puts it "Recruitment of satellite cells and increased myonucleation requires consistent "effective" training, massive amounts of food, and most importantly, time. " but one thing is for sure , there is no evidence for AR downregulation ...
i hope my contribution here has been relevent lol .
