Domestic source busted with $500k of Chinese steroids.

More than half-a-million-dollars' worth of steroids are now off the streets after largest bust of its kind in Murfreesboro history.

Police have arrested charged Leslie Parker, Jr. and charged him with possession and distribution of the illegal steroids.

"This is a major break in the pipeline of steroids coming to middle Tennessee," said Kyle Evans with the Murfreesboro Police Department.

More than 500-thousand dollars' worth of pills and injectables were found in a downtown Murfreesboro storage unit.

Evans said the steroids are shipped undetected from Shanghai, China to New York City. From there they go by express mail to Murfreesboro. In many case, police said the steroids end up at gyms and health clubs.

NewsChannel 5 spoke to a confidential informant who confirms despite the illegality and health risks the demand remains huge.

"It's in every gym in middle Tennessee, no question," he said. "You can see a guy bench pressing 275 one week and five weeks later he's doing 400 pounds."

Detectives said people pay big money for those results. A vial of testosterone like this sells for fifteen-dollars in China and can go for more than $100 here.

Parker is free on bond. NewsChannel 5 reached him by phone and asked if he is a steroid dealer.

"No, I completely deny it," said Parker. "There's a lot more to this story than meets the eye."

Parker and his attorney said they aren't ready to discuss any more at this time.
