For things like this, Jay can't win with the fans. If he denies using steroids, everyone would be screaming "What an F-ing liar!" If he flat out said, "Of course I use steroids!" he'd be called an idiot for admitting it. Just look at all the ninnies who think they've stumbled upon some sort of "secret confession" and won't stop yapping about it. I still don't get what the big deal is. Jay said the only possible thing that neither brought him any hardship nor required him to lie.
I'm yet to read anything that would have satisfied everyone any more than what he said.
