First let me say "Welcome". Now with that out of the way here is a thread you might wnat to read.
Now you do know that this is a board about lifting (BBing, Oly, and PLing)? There are not a lot of guys that use Fina or Duta. Heck most guys just shave their heads.
But since you have had a transpant I would suggest Fina and Dr. Lee's Xandrox 5%.
As for fina I used it for six years and it only help a little. I had no noticable sides. I could still get hard when ever I needed too. And everything worked. Don't forget that most of those studies that qoute those horrible side effects are almost the same statisticly the as a plecebo.
Now I use duta which for ME is so much better. I have regown a large degree of hair, esp when I combine it with Xandrox.
If you have any specific questions Big V or I would be more the happy to help.
