This document is the United States Anti-Doping Agency's (USADA) reasoned decision on disqualifying and declaring ineligible Lance Armstrong for anti-doping rule violations. It details evidence from numerous witnesses and scientific testing that Armstrong possessed, used and trafficked banned performance enhancing drugs including erythropoietin (EPO), blood transfusions, testosterone, and corticosteroids from 1998-2005. It also describes how Armstrong and his team avoided positive drug tests and retaliated against witnesses. Armstrong refused to contest the charges in arbitration. The evidence demonstrated a doping conspiracy involving Armstrong and several team doctors and staff.
