I wonder what the guys smell like the day of the show. With the paint and their natural scents, I really wonder.
Definitely musky. Bodybuilders aren't supposed to wear deodorant when they get spray tanned, as it can turn their skin green. And they can't bathe once they're sprayed or the tan will wash off. So oftentimes it's at least 24 hours without washing, all while working hard to get a pump before going onstage.

I definitely reeked when I competed last. Felt so good to take that shower afterwards (though it looked like someone dumped a pot of coffee into my bathtub when the tan washed off).
