Pure testosterone.

Seriously, if you wanted a masculine name, you've hit the jackpot with Viggo. I wouldn't use the name, but I really like it. It's unique without being unmanageable. Only downside is that almost no one has heard of it outside of Viggo Mortensen, and I for one really dislike the naming-after-celebrities thing (Angelina, Miley, Charlize, Kiefer, etc.)
