There was another forum I read with a user who called himself El Duterino or something like that, and he was a serious male pattern baldness veteran. Been on dutasteride for 7 or 8 years, used everything else at one time or another. on the RU he said you can use TOO MUCH. He said his max was 20mg per day, and he had some theory as to why if you block to much the body just builds more receptors. So there is a sweet spot to his mind....
