After last week’s murmur over allegations that Baltimore Ravens linebacker Ray Lewis may have used deer antler spray containing the illegal compound IGF-1, a former NFL player is coming forward with his own admission of PED use.

Ex-Dallas Cowboys offensive lineman Tony Casillas said in a recent radio interview that he knew of players who used a medication prescribed by veterinarians for horses in order to aid in recovery.

“When I heard about deer antler spray, when I heard that, I said, ‘That’s nothing.’ We used to use this stuff called DMSO. That’s what veterinarians put on horses, on a muscle,” Casillas said. “It’s an ointment that’s like anti-inflammatory. … If you’re going to talk about the deer antler stuff, we used DMSO and people knew it. Everyone knew about it.”

DMSO (dimethyl sulfoxide) was testified about before Congress in the early 1980s, with former NFL player and coach June Jones acknowledging that its use was common among his teammates. The substance has never been approved by the U.S. Food and Drug Administration and is considered a fake cancer cure.
