Yahoo News:Hamilton retires from cycling after positive test

"Olympic champion Tyler Hamilton, once touted as the next great American cyclist and an heir to Lance Armstrong’s throne atop the sport, ended his doping-tarnished career Friday by saying he tested positive for a banned substance and would retire.

Hamilton admitted taking an herbal product for two days in February to combat depression, knowing it included a steroid.

“He has had a cloud over his career for a while now and the sport is better off without him,” said Pat McQuaid, president of the International Cycling Union.

Hamilton’s win at the 2004 Athens Games was overshadowed by a blood doping scandal. He tested positive for doping a second time later that year, served a two-year suspension and returned to racing early in 2007 – never revealing that he was fighting depression, which he said runs in his family.

Seeking relief, he took something called Mitamins Advanced Formula, billed as a “natural depression treatment with vitamins, herbs and supplements.”

“Obviously, that was a mistake,” Hamilton said.

In a statement, USADA said it will continue going through the process of issuing a sanction.

“Although Mr. Hamilton has now retired from the sport of cycling and has publicly accepted responsibility, this is a pending matter and USADA will make an announcement of the final outcome and imposition of the exact sanction in accordance with the rules when the process is complete, which should be in the coming months,” the statement said.

The Mitamins product contains common things such as vitamins D, B-6 and B-12, along with thiamin, riboflavin and calcium. Each serving also contains 20 milligrams of a steroid called Dehydroepiandrosterone – DHEA, as it’s known.

“Clinical research has suggested that taking DHEA orally might improve the symptoms of depression,” reads the company’s Web site. " … ton_doping
