Larry Olubamiwo tested positive for EPO after US DEA informed UKAD that he was linked with illegal sale of steroids and other related drugs

The heavyweight boxer Larry “War Machine” Olubamiwo took some anabolic steroids, HGH, IGF-1 and other doping drugs during 6 years. Although certain tests have been conducted earlier, he was caught just in January 2012. After a fight against Sam Sexton Larry Olubamiwo tested positive for banned drugs. Metabolites of steroids were not discovered in his sample. The athlete tested positive for EPO. EPO represents a blood boosting preparation.
Prolonged intake of banned drugs by Olubamiwo was a real embarrassment for the United Kingdom Anti-Doping. Andy Parkinson, the CEO of the UKAD, tried to prove that the ban of Olubamiwo for intake of 13 different forbidden medicines is a real success of the UKAD in the struggle against doping.  
Andy Parkinson noted that it was an unusual case. The boxer applied steroids and other related drugs for long period of time without fear to spoil his health, career and reputation. He was sentenced to 4-year suspension.
But the alarming fact is following: Olumamiwo could avoid detection for long time, despites great efforts of anti-doping officers to “clean” sports from intake of doping drugs.
Olubamiwo was caught just because the UKAD was informed by the United States Drug Enforcement Administration (DEA) that he became the target of an investigation linked with illegal sale of anabolic steroids and other related drugs in the US. Then the UKAD conducted a test which resulted in positive results for EPO.
Robert Smith, the General Secretary for the British Boxing Board of Control, supported the statements of Andy Parkinson about efforts and success of anti-doping agencies. He noticed that the case demonstrated that cheating couldn’t be hidden.
What is your point of view about the case? Do positives for EPO and the suspension of Olubamiwo manifest that anti-doping officers succeed? Or does the case show that anti-doping policy is not proper?
Each person may make own conclusion. But it is clear that the sportsman could take various forbidden preparations for six years without being caught by anti-doping officers.
