UKAD: Larry Olubamiwo’s doping case is unusual

The heavyweight boxer Larry “War Machine” Olubamiwo applied several anabolic steroids, HGH, IGF-1 and other related preparations during six years. However several tests have been conducted earlier, he was caught just in January 2012. After a fight against Sam Sexton Larry Olubamiwo tested positive for banned products. Metabolites of steroids were not found in his sample. The boxer tested positive for EPO. EPO represents a blood boosting drug.
Long-term 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 prove that the suspension of Olubamiwo for usage of 13 various banned medications 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 medications for prolonged time without fear to spoil 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 significant 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 positives 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 affirmed that the case demonstrated that cheating couldn’t be hidden.
What is your opinion about the case? Do positives for EPO and the suspension of Olubamiwo display that anti-doping officers succeed? Or does the case demonstrate that anti-doping system is not proper?
Anyone may make own conclusion. But it is clear that the sportsman could take various banned preparations for six years without being detected by anti-doping officers.
