Question for Propecia users and their DHT levels.

[FrankieRed]

Those of you on Propecia:

Did any of you guys have blood work before starting Propecia, and then have follow up blood work while using propecia???

If so what where your DHT levels before treatment, and what were your DHT levels during treatment?

I realize that everyone is different, but I'm trying to gauge by consensus how low the DHT levels need to be knocked down in order for Propecia to hold off hair loss.
