Strange bruising to players at the time suggests their involvement in illegal supplements.
Former Cornulla Sharks head trainer Trent Elkin has vehemently denied using banned peptides on himself to see if there were any sides affects.
Elkin was the head trainer at the time when he hired sports scientist Stephan Dank, who is considered one of the key witnesses in the Australian Sports Anti-Doping Authority probe into illegal drugs.
Both Elkin and Dank have denied they have ever condoned or administered any illegal peptides.
However, the independent Kavanagh report commissioned by Cronulla, is said to reveal Elkin used the drugs on himself and had blood testing done to ascertain any affects.
“After the substances CJC-1295 and GHRP-6 were supplied to the club Elkin took it on himself to test the substances by self-administering them and then having his blood tested,” the report said.
