I've tried Arginine. Doesn't work. Yohimbe, Ginseng, etc. When you have propecia dick, nothing will work. It's dead. Well, maybe v**** but who wants to start that cycle of dependency. As for it getting back to normal, not after a few months. It may take your hair a long time to show results but from what I've heard your hormone balance should be back in a few weeks, maybe 2-3 months, but after that there's no way. I've been to 2 doctors who have told me this. Actually 3 if you count the derm. Moral of the story: this sucks!!!!!!
