Former Essendon sports scientist Stephen Dank listed banned drugs on the consent forms given to Essendon players. CLUB documents show some Essendon players were prescribed the anti-obesity drug AOD-9604 last season. But Essendon last night insisted consent forms revealed today by the Herald Sun did not prove any of its players used the substance, which is banned for use by athletes. The forms signed by Bombers players and officials reveal key details of the supplements program at Windy Hill in 2012. They show some players were recommended weekly injections of AOD-9604. Injection schedules for Thymosin are also documented. Some types of Thymosin are banned by doping authorities. Mark Robinson: Confusion continues at Essendon The forms state that "all components of the intervention are in compliance with current WADA anti-doping policy and guidelines." An Essendon spokesman said last night: "It is a matter for ASADA to determine these matters." The club certainly does not accept that the signing of the consent forms means that the supplements were administered, and this kind of speculation is just unnecessarily harmful to the players. Bombers re-sign 'champion' Heppell The dosages and number of injections planned to be given to individual players are detailed in the forms. Australian Sports Anti-Doping Authority investigators have begun grilling Essendon players on their participation in and knowledge of the club's supplements program. Bombers chairman David Evans said this week his club had "never conceded that our players have been given banned substances in 2012." He said the club was becoming increasingly confident its players would escape penalties. The consent forms appear to remove any doubt that at least one substance - AOD-9604 - prescribed to some players did fall outside anti-doping rules. If issued with an infraction notice by ASADA, it will be up to lawyers for the players and the club to argue why this was not a breach. It is known some Essendon players refused to be injected as part of the supplements program. The signature of Dank appears on all the documents as well as that of a witness and the player the program was devised for. The World Anti-Doping Agency has stated that AOD-9604, which is not approved for human use, is banned. Asked about the status of Thymosin, an ASADA spokesman said last week: "The status of Thymosin in sport is dependent on the type of Thymosin ... for example, Thymosin Beta 4 has been prohibited under S2 of the WADA Prohibited List since at least 2011." Essendon has not said which type of Thymosin its players were recommended by Dank. Melbourne biochemist Shane Charter has claimed Dank ordered the banned Thymosin Beta 4 from him last year.
