Testosterone Keychain

If there's anything in the world manly enough to hang with your keys, it's gotta be this. The Testosterone Keychain ($22) is a 3" pewter recreation of the molecular structure of the male sex hormone, attached to a black anodized steel spring ring to hold your keys. It even comes in a gift box with an informational tag about testosterone. Geeky, yet manly. [Thanks, Liz]
