STEPHEN Dank is set to unveil evidence he claims will clear 34 past and present Essendon players facing charges arising from the Bombers’ controversial supplements scandal.The man many believe is at the centre of the investigation is also set to sue the AFL.Almost 22 months after the Bombers' alleged peptide regime engulfed the AFL, the players' case will go before the League's independent anti-doping judiciary late on Tuesday.The AFL handed down 34 infraction notices to past and present Essendon players on Friday.After promising for 21 months to reveal information, Dank is set to roll out evidence he believes proves the players' innocence.It centres around Thymomodulin, a legal supplement the biochemist claims was used instead of Thymosin beta-4, the illegal substance which prompted infraction notices."It's an amber vial of Thymomodulin, clearly dated July 28, 2012," Dank told Sportsday radio.
