ASADA will reopen an investigation into whether Stephen Dank provided a banned substance to AFL club Gold Coast.
It follows the bombshell media revelation that Dank allegedly admitted trafficking CJC-1295 to former Suns player Nathan Bock.
The national anti-doping agency said Dank continued to be unhelpful.
It also approached the Herald Sun journalist who wrote the story to provide details of the conversations he had with Dank.
“ASADA considers all information relating to potential anti-doping violations, and this new information, particularly its veracity, will be assessed by our investigation unit,” the agency said in a statement.
It added that Dank had refused to speak to ASADA investigators for three years in the wake of Essendon and Cronulla supplements debacles.
“ASADA spoke with Mr Dank today, and he again refused to offer any assistance or information,” it said.
“Mr Dank’s alleged admissions overnight are starkly at odds with his previous position on the matter, as ASADA notes he is currently appealing the AFL Tribunal’s finding that he attempted to traffic CJC-1295 to the Gold Coast Suns.”
The statement also said that ASADA needed reliable evidence to pursue doping allegations.
According to the Herald Sun report, Dank was asked if there was any doubt whether the drug he supplied Bock was CJC-1295.
“No. There is no doubt in my mind,” Dank is quoted as saying.
On the weekend, it emerged that ASADA had decided not to appeal against another AFL tribunal verdict that cleared Dank of trafficking CJC-1295 to the Suns.
