I know I fought T levels for my first year of HRT.  It wasn't till my GD put me on Progesterone.  I am not at 5 for serum T.

Oh wow ... I am mobile right now, so i will have to read those reports later..

Herbal WP, took my T down to below what a few of my girlfriends had on Spiro.
A low dose Spiro for me killed my T completely.
Now with just Estrogen and no Spiro, my T is at orchiectomy levels.
