Heavyweight boxer Larry Olubamiwo finally tested positive for EPO

The boxer Larry “War Machine” Olubamiwo applied several anabolic steroids, HGH, IGF-1 and other related drugs during six years. However some tests have been conducted earlier, he was caught just in January 2012. After a fight against Sam Sexton Larry Olubamiwo tested positive for forbidden preparations. Metabolites of steroids were not found in his sample. The athlete tested positive for EPO. EPO represents a blood boosting product.
Long-term usage of forbidden products 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 forbidden medications is a real success of the UKAD in the struggle against doping.  
Andy Parkinson affirmed that it was an unusual case. The boxer used steroids and other related medications for prolonged time without fear to destroy his health, career and reputation. He was sentenced to 4-year ban.
But the alarming factor is following: Olumamiwo could avoid detection for long time, despites essential efforts of anti-doping officers to “clean” sports from intake of doping medicines.
Olubamiwo was caught just because the UKAD was informed by the United States Drug Enforcement Administration (DEA) that he was implicated in an investigation connected with illicit sale of anabolic steroids and other performance-enhancing 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 officers. He confirmed 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 ban of Olubamiwo manifest that anti-doping agencies work successfully? Or does the case demonstrate that anti-doping policy is not appropriate?
Anyone may make own conclusion. But it is clear that the athlete could administer numerous banned medicines for six years without being caught by anti-doping officers.
