CCS,
The only way to really find out about spironolactone is to put it on some of your BEARD hair for about one good month, and see if it reduces its growth.
Ive tried two things previously that reduced BODY hair........revivogen, and pine oil
Now Im using somehting that is definitely reducing my beard hair............peppermint oil mixed with water at about a 1-50 or so ratio. Green tea extract had a slightly negative effect on beard hair at about 1.5 months, but not as much as the peppermint oil. I'd like to give spironolactone a whirl up there as well as revivogen to see which does best. Then I will be out of ideas.
The new cloning pics from ICX have me optomistic that everything will be moot in a few more years time. They have me psyched.
