UKAD could ultimately catch boxer Larry Olubamiwo

The boxer Larry “War Machine” Olubamiwo used some anabolic steroids, HGH, IGF-1 and other related drugs during 6 years. Although several tests have been conducted earlier, he was caught just in January 2012. After a fight against Sam Sexton Larry Olubamiwo tested positive for forbidden products. Metabolites of steroids were not found in his sample. The athlete tested positive for EPO. EPO is a blood boosting medication.
Prolonged application of prohibited 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 usage of 13 various banned products is a real success of the UKAD in the struggle against doping.  
Andy Parkinson noted that it was an unusual case. The boxer administered steroids and other related drugs for prolonged time without fear to destroy his health, career and reputation. He was sentenced to 4-year suspension.
But the alarming aspect is following: Olumamiwo could avoid detection for long time, despites essential efforts of anti-doping officers to “clean” sports from intake of doping medications.
Olubamiwo was caught only because the UKAD was informed by the United States Drug Enforcement Administration (DEA) that he was implicated in an investigation linked with illicit 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 statements of Andy Parkinson about efforts and success of anti-doping agencies. He noticed that the case manifested that cheating couldn’t be hidden.
What is your point of view about the case? Do positives for EPO and the suspension of Olubamiwo demonstrate that anti-doping agencies succeed? Or does the case demonstrate that anti-doping system is not appropriate?
Everyone may make own conclusion. But it is clear that the boxer could administer different forbidden products for six years without being detected by anti-doping officers.
