Just estrogen has shrunk me _ down.  The epidimus (sp?) did not shrink so much.
I started on a high dose of Androcur which did not bother me at first.  It started to run my adrenal function down though.  On estrogen alone I am still have high enough T to cause me to notice  

.  I can take a small dose of Androcur and it is often effective

Dutasteride is what I am using now.  I have only been on it for the first two days, but so far so good!  On estrogen alone I had zits all over my back.  Androcur didn't really help either with the amount of cheese I was eating.  The zits seem to be going away now.  The jump in regular T hasn't been too bad.  The SHBG worries me.  That could turn me into a college girl or something.
I would like to try spiro.  Especially as I am planning on including natural progesterone in the near future (blocks T but is also a precurser).
Oh yeah, Nizoral/ketoconazole shampoo'ng directly on the military intelligence is good for about 8 hours of testoterone shut down -- more effective than anything else IMO.  I leave it on and shave my legs or something and then shower.  It is numbing or something so don't get it on your sensitive areas (I use packing tape).
