4 month UPDATE: Well, I really can't tell what's going on with this stuff. I have not lost a lot of ground but haven't gained any either. Either I am still slowly losing my hair or it has stabilized. I guess it's still too early to tell. I am definitely a Norwood 3 now though, my hair is longer so I can tightly pull it back. Losing ground in the front forlock too. It's very very depressing to see that. I don't know anyone in my family that's a Norwood 4, or who was one at my age, but it seems that is where I'm going.
Getting a haircuit tomorrow so I will take pictures where I can compare to my starting pictures a bit better. As for side effects, haven't had any ball ache or anything in weeks. Zits have pretty much gone away. One thing I have noticed is I can't get very strong erections lately. My libido is also gone. There could very well be other personal psychological factors associated with this though so I am not ready to blame the pill. I have tons of energy and have lost no strength and I am actually less depressed nowadays than I was a few weeks back. So I do not think my libido drop has to do with hormones, as I imagine a hormonal drop would also lead to loss of strength, body hair, motivation etc, right? Or does DHT just affect libido and erections? Not sure. Anyway, I will probably update at the 6 month mark. I really hope I see some concrete evidence by then.
I will probably post some before/after pics by the 6 month mark. My starting pictures are pretty detailed and in good lighting, but it's difficult to get all of the angles right and my haircut will be somewhat different. Might post them before that but I really see no real difference in my hairline or density.
