Okay, just as I thought.
What I think, is that you don't have that much DHT, and that's why your hair loss isn't that aggressive. I'm 23 and NW3, been balding since 15. I think I have a lot of DHT. I'm on 1.25mg a day for 1 year and 8 months, and I get a boner for just about any semi-cute girl, with big boobs OR a pretty face, in college, that I think about at home. Lol.
I think I have so much DHT, that the best finasteride could do is just slow down my hair loss, or maybe stop it, but never regrow my hair. While you have just a just a bit of DHT, so finasteride completely depletes all of it, causing you to get these "sexual side effects", as well as what you said, giving you more density, which fin has never done for me. This means that you are a very good responder to fin, I think. And i'm just in the percentage that gets "no further loss".
I've been drinking J.W. Black Label today, so I don't know if I said anything stupid in this thread, I just finished my last cup for the night, no more for me. I'll re-read it tomorrow. I'll probably laugh at what I ever typed today. But these are my actual sober thoughts I wanted to tell you[everything except the big boob girls part], I just don't know if I worded them correctly since i'm a bit "tipsy". I just hope you get my point.
