Human ties were a significant influence on my development activities in Chapter 4, including through direct recommendations or suggestions about how I should proceed. It is clear from the results of our decade of testing that retailers and distributors, including online marketplaces, do not effectively prevent these types of potentially harmful products from being sold to consumers. Armstrong was tested hundreds of times for more than a decade but never produced a positive result. Found guilty, the American Olympic sprinter tested positive a total of three times in his career. His career, however short it may be, is relatively clean, having never been caught or having a test result come back as positive for a drug test. Lance Armstrong's confession, after years of aggressive denial that he took banned substances, reveals the magnitude of the challenge drug testers face. Lewis, although admittedly guilty for taking steroids, said that he wasn't concerned about any sort of revelations related to him because it was so long ago, regardless of his long history of 18 years of track. So far, this defensive end has not been charged with taking illicit, illegally-banned substance performance enhanced drugs.
