Lance Armstrong won the Tour De France 6 years in a row. The fact that he was using performance enhancing drugs should have be apparent. Don't you think? What are the odds that the same guy could win that race that many times in a row.

NEW YORK -- Tyler Hamilton, a former teammate of Lance Armstrong, told "60 Minutes" that he used performance-enhancing drugs with the seven-time Tour de France winner to cheat in cycling races, including the tour.

Hamilton says Armstrong took a blood-booster called EPO in the 1999 Tour and before the race in 2000 and 2001. Armstrong won the race every year from 1999-2005.

The interview with Hamilton was broadcast on the "CBS Evening News" on Thursday.

"I saw (EPO) in his refrigerator. ... I saw him inject it more than one time," Hamilton said, "like we all did. Like I did, many, many times."

Hamilton told "60 Minutes" reporter Scott Pelley: "(Armstrong) took what we all took ... the majority of the peloton," referring to riders in the race. "There was EPO ... testosterone ... a blood transfusion."

EPO is a drug that boosts endurance by increasing the number of red blood cells in the body.

Armstrong has steadfastly denied doping and has never failed a drug test. However, federal authorities are investigating whether Armstrong and his former U.S. Postal team did participate in a systematic doping program.
