Where to go for 5 AR activity tests in our body, any information?

I want to make sure our 5 ARs are working fine in all of our body parts. If any body knows where to go for tests, I will try to do that.

I have been thinking our problem being as AR defect but after reading many posts about Arimidex users who are suffering more or less like us( impotence, muscle weakness, joint pain , muscle loss etc) makes me wonder if our 5 AR is working fine in our our body.
There are many posts in musclechatroom and messomorphosis about sides from Arimidex use but not from Nolvadex or Clomid. I think we can compare Arimidex with Fin. Fin inhibits 5 ARs where as Arimidex inhibits Aoromatase enzyme.
Does this mean our problem is caused by enzyme inhibition? not because of Receptors or I am wrong? I mean both fin and arimidex cause receports problems. One messes up Androgen and later messes up estrogen receptors?
