The 90-minute broadcast will be followed Friday with a second part on the Oprah Winfrey Network on Friday, the second installment of a 2½-hour interview taped on Monday.

The first interview

Armstrong opened the interview by saying “yes” to taking the banned energy boosting substance EPO, testosterone, HGH, cortisone and employing blood-doping practices and transfusions.

He said he started using in the “EPO generation” of the mid-1990s.

And he said that without using the performance-enhancing drugs, he would not have been able to win the seven Tour de France titles.

He also expressed regret at how he had “bullied” those who painted his success as fraudulent.

He sued his former masseuse, Emma O’Reilly, after she had revealed that he had wrongly backdated a prescription for banned cortisone after he tested positive for it in 1999.

“She’s one of those people I have to apologize to,” Armstrong said. “She got run over, got bullied. We sued so many people. I have reached out to her to make amends.”

Winfrey asked Armstrong why he has sued people when he knew they were telling the truth.

“It’s a major flaw,” he said. “A guy who wanted to control every outcome. To never forgive me, I understand that. I have started that process to speak to those people directly.”
