Fresh from his victory over American boxer Shane Mosley, Philippine boxing sensation Manny Pacquiao arrived in Manila early Monday to rebut allegations making the rounds on the internet over his supposed use of performance enhancing drugs. Speaking to reporters upon his arrival at Ninoy Aquino International Airport, Pacquiao readily responded to questions about his supposed use of performance enhancing drugs (PEDs). In focus: Manny Pacquiao Pirated DVD merchants cash in on Pacquiao\'s popularity Pacquiao\'s latest victory thrills yet disappoints UAE fans Two days prior to his arrival in Manila, an internet blog posted by a Filipino boxer who claimed to be Pacquiao\'s sparring partner who called himself the \"Injector\" claimed that he regularly administered the Filipino boxer with PEDs and human growth hormones whenever he took to the ring in the United States. Absurd But the eighth-time world division boxing champion denied this. \"There is no truth to that,\" he said in an interview on radio station dzMM. He said the statement by the \"Injector\" was aimed at besmirching his reputation. Pacquiao\'s adviser Michael Koncz described the rumour as \"absurd,\" because for one thing the boxer never had a compatriot for a sparring partner since he started practising in the United States. Pacquiao said that it would be impossible for him to use PEDs because of the rigorous drug testing in the US. The boxing sensation said he and his lawyers are trying to trace the source of the rumour and are planning to file legal action against those behind it. Pacquiao said the rumours were being spread by people who are envious of his achievements. From : Gulf News
