you are reposting the same studies.
the first with the same erroneous conclusion. ATD does not inhibit T binding, suppression of oestrogen reduces AR receptor expression in those tissues.
with respect to your claims about 17a-methyl-17b-hydroxyl-3-keto-delta 1,4,6-etioallocholtriene (taken directly from ALRI who developed this compound), there are no studies to back up these claims.
with respect to RIA anaylsis, its been proven to be quite innaccurate.
