I am not a doctor.
I had the same thing happen to me but I am left with finasteride. My PA said I did not need dutasteride.
My particulars:
T 24 ng/dl, high dose finasteride, oral E and AA. The E has sex hormone binding globulin (SHBG). I do not know my free T but it must be extremely low as I am regrowing a lot of hair.
