Bumping this thread to post an update...
It's been 8 weeks since I started taking DHEA and my body seems to love this stuff. I started seeing new eyebrows and facial hair by the second day. My arm hair exploded shortly after that and now my forearms are almost completely covered. Chest and stomach hair is still peach fuzz, but there's a ton more of it. It's finally started getting darker this last week, so maybe I'm close to having real hair there too. The hair growth has been really weird like that - like all of a sudden a huge patch of hair pops up in a new area.
Unfortunately, my workouts have been too inconsistent to see much muscle growth, but it does seem like it's easier to build muscle when I do lift. And the muscles I do get are...umm...harder, I guess. I don't know how to explain that one - they just feel different than before when I'd workout. My skin's also become rougher and doesn't dry out as easily, which is awesome since I was going through bottles of lotion because of the dry climate here.
All in all, I'm happy with the small changes and will probably keep taking the DHEA until I get on real T later this year. My results may not be typical, though, so I'm not saying it'll work for anyone else. I'm older than a lot of you guys (36) and DHEA is recommended more for people over 35 because our bodies stop producing it as we age. I've also long suspected that I have unusually high testosterone and my body's reaction to the DHEA seems to confirm that (or maybe my body's more sensitive to the T it does get...something like that). Ok, that was a really long-winded way to say YMMV.
