Thank you all.
My baseline testosterone level is 10.4 pg/ml. Sorry for the nebulousness.
Grace and Emma, that's is kind of what I meant. This guy could talk!

And he drew pictures with lots of arrows linking the hypothalamus (?) and the testes and then started crossing arrows out. And though I knew what he was talking about I kept having to try to remember the English equivalents of all these medical terms to keep up. In a whirlwind spiro was proposed and rejected. I can't remember the reason why :O
Anyway, thank you for all of your input Jill, Grace, Jenna Marie and Gwynne. It's good to know that it is a fairly common regimen and that is working or has worked for you.
I guess I wanted some more aggressive T-blocking in the hope that it would reverse some of my hair loss. If E blocks T production then alone then maybe I don't need to worry.
