There are numerous giant truths that keep being avoided and denied about doping.
#1- Doping has never been proven to help any athlete to have results any better than could already be obtained by numerous natural means, and which are usually much better;
#2- The testing procedures are pseudoscientific, faulty, and based entirely on conjecture;
#3- The faulty pseudoscientific testing procedures are not subject to valid scrutiny;
#4- Banned substances proliferate and are ubiquitous in the general food supply;
#5- The extreme likelihood of disgruntled and/or mentally disturbed persons (and/or deranged supporters) who've been able to sabotague a competitor who's been performing much better.
