A new report from the US Anti-Doping Agency reveals overwhelming evidence that pro-cyclist Lance Armstrong was heavily involved in a massive doping scheme.

1000 pages of evidence provided by the agency include first hand accounts, scientific documents, financial payments, emails and lab tests that show quote "undeniable proof" that Armstrong was not only a willing participant, but the ringleader of a sophisticated doping ring.

11 former teammates gave sworn testimonies admitting they had used and were a part of the doping scheme.... the most surprising being that George Hincapie who was thought to be one of Armstrong's most loyal and trusted friends.

Armstrong has never failed a drug test and has always denied any wrongdoing.

But last month he received a lifetime ban from professional cycling last when he decided not to defend himself against USADA's doping charges.

At the time, he challenged the agency to prove its case. They did so with the release of the report.

Armstrong has so far not responded to the report.

The International Cycling Union has 21 days to file an appeal.
