Does the finasteride (1mg/day) affect your sexual desire/performance? I tried Propecia for a few weeks back in '98 and fuck that! No more! I'd rather use topicals UNLESS I was taking exogenous testosterone (i.e. juice). No way could I take finasteride the rest of my life. They discovered that shit from a plant in the jungle where you couldn't tell the young boys from the young girls because boys had micro-penis. Why do you think Propecia has a warning for pregnant women to avoid contact with the pills? Because the birth defects they are warning about is micro-PENIS! DHT is responsible for a lot of manly things besides the unfortunate hair-loss the the majority of men genetically pre-disposed.
