What do you make of it?

CENA: Obviously, Chris supplemented testosterone between April and the time of the tragedy. Now --

KING: I mean but why?

What do you take -- what do you take it for?

CENA: I don't -- I'm not a doctor. Larry, I don't know. And that's something that I'm really uneducated about. I wish I could help you out there, because maybe that would help us. Maybe that would give another theory to what's happened.

But as far as testosterone supplementation, I -- I can't give you an educated answer, so I don't even want to theorize.

KING: John, thanks, as always, for joining us.

We look forward to seeing you soon.

CENA: No, thanks for having me back, man.

I appreciate it.

KING: John Cena, the WWE champion and superstar.
