More on Tyson Gay failed drug test.

SI has learned that Gay has been treated by Atlanta chiropractor and anti-aging specialist Clayton Gibson. In the sports world, the term “anti-aging” has often come to signify therapy that uses hormones — usually testosterone and HGH — and testosterone precursors, like DHEA. DHEA can be obtained over the counter and is permitted in certain sports, including baseball, but not those contested in the Olympics.

 

Reached by phone, Gibson told SI that he began working with Gay before the Olympic trials last year, and that he had no information beyond that Gay had been informed of a positive test. “We had [Gay’s] blood tested and everything before the trials just as an evaluation and taking a history to learn about the patient,” said Gibson.

Asked whether he provided Gay with a product containing a substance — such as DHEA or testosterone — that is banned in track and field, Gibson declined to comment “until I talk with Tyson.” Gibson did say that, “what I have is all food-based products and herbals as well as homeopathic products. That’s the only thing we have in our office. We don’t have anything synthetic.” DHEA and testosterone often come in creams containing substances banned in track and field. Asked if he makes creams that might contain substances banned in track, Gibson said he was not sure and that, “I don’t make creams,” but added, “We have labs that make those.”
