Lance Armstrong says ... if he had a time machine to go back to the '90s, he would NOT have stopped himself from doping ...saying, "I would probably do it again."
The disgraced cyclist spoke with the BBC about his decision to cheat -- and if he's learned anything along the way.
"If I was racing in 2015, no, I wouldn't do it again because I don't think you have to," Lance said.
"If you take me back to 1995, when doping was completely pervasive, I would probably do it again."
Armstrong also says there was a silver lining to his cheating -- explaining that his LiveStrong charity foundation went from "raising no money to raising $500 million, serving three million people".
"Do we want to take it away?" Lance asked .... "I don't think anybody says 'yes.'"
