I'm on the same regimen as you guys - just revivogen. I've been using it once a day for about 5 months. I honestly don't remember when I started, but it's been a while. I've skipped a few days here and there, but I've been pretty consistent with it. Just like you guys, I can't really tell if it's doing anything.
I have diffuse thinning mostly on the vertex. I still shed like crazy in the shower, and some days it's pretty tough to hide my hairloss. I'm 26 now and I used to have very thick hair just a few years ago, so this really came as a shock.
I tried propecia for a short while, and immediately noticed adverse sexual effects so I stopped. I agree with you guys - the chance of keeping my hair is not worth the possibility of long term damage. I've come to accept that I'll eventually be bald, but hopefully I can slow it down. Maybe I can buy some time until a new treatment comes out.
The smell of revivogen doesn't bother me too much anymore, but I have stained my pillows and the wall behind my bed. I apply it at night about an hour before I sleep. Keep me posted with your results. Good luck.
