Dude, My Testosterone’s Pushing 1290. How About Yours?

One time, life hacker/professional guinea pig Tim Ferriss and I got a blood panel done together. Then we learned to butcher a side of beef, shot each other with foam arrows in San Francisco’s Glen Park, and did a kettle bell workout with a $5 make your-own-kettle-bell with disc weights and one-inch pipe. Yeah, that was a day. Or, rather, it was a 4-Hour Make-Over from The 4-Hour King.
