Dong Hyun Kim Says 90 Percent of UFC Fighters Are on Drugs

If fighters in the UFC aren't being pulled from upcoming cards due to injuries, they're serving suspensions for banned substances.

That's been one hot-button issue hanging over the promotion during the last handful of years, and welterweight competitor Dong Hyun Kim is sick of it. In fact, "Stun Gun" claims that nearly every fighter in the company is using performance enhancing drugs (PEDs) of some sort.

During an interview with South Korean outlet MFight (via Middle Easy), Kim also made the bold claim that 90 percent of UFC fighters are doping:

"

While a lot of people believe doping tests work, just like a breathalyzer test you can get away with it by just controlling timing. Most of the steroid users just cycle and get by the tests. It's almost like other athletes look down on you as an idiot if you don't do steroids. It's like non-users are bicyclists while steroid users are racing with motorcycles. But I am one of those "idiots" that don’t use performance enhancers. I would say 90 percent of UFC fighters use performance enhancers.

"

Although Kim has yet to face a UFC fighter who's tested positive for PEDs, he once lost a fight against Karo Parisyan by split decision, who was later outed for using illegal painkillers.

However, several fighters have tested positive for drugs and PEDs in 2011 and 2012 alone.

As it stands, the most high profile offenders for PEDs include Stephan Bonnar, Thiago Silva, Muhammed Lawal, Chael Sonnen and Cristiane Santos. Additionally, Nick Diaz, Matt Riddle and Dave Herman have also been suspended for marijuana use during this year.
