Finasteride actually raises total test and estrogen slightly because less Test is converted to DHT. You never know how someone will react though. Lots of nightmare stories out there about it. I personally have used it for a very long time without much issue. I'd try to hold off as long as possible though. 25 could be a little young[/QUOTE
What age would you recommend starting? Do you agree with the 1mg starting point?
I'd suggest a couple of things.
Before starting the drug, make sure you do a baseline blood panel to find out your free/total test, dht, and estrogen.
You may not need to start at 1mg. .5 might do the trick to bring you under the level that is causing the hair loss.
After 30 days do another full panel to find out what your ratios have changed to. See what that extra dht is being converted to. Your free test will probably rise. Hopefully your estrogen stays down. You also may get some conversion to Aldosterone which may cause some bloating.
Log any sides in a journal with dates and how long they persist. You may experience none, and you may experience a few, and some of them may go away after your body adjusts.
