Epilobium and Flaxseed.
I would try Flaxseed first as Epilobium reduces both DHT and Estradiol "supposedly" and by using it in conjunction with Finasteride you would in "theory" be inhibiting more DHT and causing greater conversion (increases) in Estrogen to which the Epilobium itself could not handle. So I have been told.
So, Flaxseed... I've considered trying it to see the effects it any and despite this it is cheap.
