Biochemist Shane Charter plans to detail alleged peptides regimen at Essendon Biochemist Shane Charter is set to break his silence on Essendon's alleged peptides regimen. SHANE Charter, the biochemist embroiled in the drugs-in-sport scandal, will detail Essendon's alleged peptides regimen to the Australian Sports Anti-Doping Authority. His former associate, controversial sport scientist Stephen Dank, seems certain to be summoned to a Senate inquiry into sports science, scheduled to start in June. Dank, who is at the centre of the Essendon and Cronulla anti-doping investigations, could be one of several people compelled to talk to the Senate inquiry about accreditation, code of conduct, substance use, sourcing of supplements and athlete welfare. Failure to appear could result in contempt charges and carry a six-month jail term. Charter - who says he sourced an array of materials on request for Dank - is already co-operating with the joint AFL and ASADA probe into the crisis, and spoke with ASADA in recent weeks. Charter told the Herald Sun last night he expected to supply detailed information to investigators about exactly which peptides had been supplied to Essendon. "I will be going to see ASADA next week," he said. The Bombers saga took a twist last night when Dank said he had approval from the World Anti-Doping Agency to use the anti-obesity drug, AOD-9604, which is banned. Dank said he would produce the email in court, but WADA denied any such correspondence would exist. Dank has claimed everything he administered was within sports doping rules. The Bombers, meanwhile, said they had not conceded their players were administered any banned drug. The Senate inquiry, which has been initiated by Greens senator Richard Di Natale, will have its terms of reference put to the Senate during Budget week, May 14-16. If agreed to, the inquiry will go ahead in June. A Senate committee will list witnesses it wants to hear from - a list almost certain to include Dank. "It's not about him as an individual," Senator Di Natale said. Our intent will be, 'What do we need to put in place to make sure the health of athletes is protected?'. Asked if witnesses were required to attend, Senator Di Natale replied: "The Senate has the capacity to compel witnesses to appear." Senator Di Natale said tighter checks and balances were needed for accrediting sports scientists. "The issue for us, when someone calls themselves a sports scientist, how do we know they've got the skills and experience they need, and what's the accreditation process?" he said. Senator Di Natale said that in the UK, the accreditation conditions for sports scientists demanded clear parameters about background, which included "500 hours of supervised experience." "It needs to develop a real thorough accreditation process," he said. The inquiry will also cover health concerns for all professional athletes, as well as regular country and metropolitan sportspeople. with Carly Crawford and Michael Warner
