Heavyweight boxer Larry Olubamiwo finally tested positive for banned drug

The heavyweight boxer Larry “War Machine” Olubamiwo took certain anabolic steroids, HGH, IGF-1 and other doping drugs during six 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 forbidden medications. Metabolites of steroids were not found in his sample. The boxer tested positive for EPO. EPO represents a blood boosting preparation.
Prolonged usage of forbidden preparations by Olubamiwo was a real embarrassment for the United Kingdom Anti-Doping. Andy Parkinson, the CEO of the UKAD, tried to note that the ban of Olubamiwo for application of 13 different prohibited medicines is a real success of the UKAD in the struggle against doping.  
Andy Parkinson noted that it was an unusual case. The boxer used steroids and other related preparations for long period of time without fear to spoil his health, career and reputation. He was sentenced to 4-year suspension.
But the alarming factor is following: Olumamiwo could avoid detection for long time, despites great efforts of anti-doping officers to “clean” sports from application of doping medications.
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 related to illegal sale of anabolic steroids and other doping drugs in the US. Then the UKAD conducted a test that resulted in positive results for EPO.
Robert Smith, the General Secretary for the British Boxing Board of Control, supported the affirmations of Andy Parkinson about efforts and success of anti-doping officers. He claimed that the case demonstrated that cheating couldn’t be hidden.
What do you think about the case? Do positives for EPO and the suspension of Olubamiwo manifest that anti-doping officers work successfully? Or does the case manifest that anti-doping system is not suitable?
Everyone may make own conclusion. But it is clear that the boxer could apply various prohibited drugs for six years without being detected by anti-doping officers.
