im taking it oral , 10 mg a day. My theory is that cox2 is the problem.. look it like this.
Your driving a car, and then you suddenly think about something that takes away you concentration, then suddenly you cant controll the car, and then you crash.
now think like this, driving car is dht its something we all have it in minimum or large doses, something that takes away concentration is cox2 , which is sending the messages for pgd2, now when you cant controll the car which represents pgd2 because something is starting which is not bad for you, and then the crash which represents baldness. the problem lies with in cox2 i think by blocking it you will have no balding... yes you can say that pgd2 causes baldness, but without cox2 it wouldnt even be there in the first place... pls correct me if im wrong..
