NRL club Manly says it "never had any concerns" about the practices the club embraced under sports scientist Stephen Dank.
Dank's name has been linked to the supplement inquiry enveloping Essendon, with the Australian Sports Anti-Doping Authority (ASADA) and the league's integrity unit asked to look into possible misuse of supplements by players last season.
Dank left the Bombers midway through last season.
The media-shy Dank worked for Manly between 2006 and 2010, where he was an integral part of making the club a leader in sports science in Australia.
The Sea Eagles, who won a premiership in 2008, released a statement confirming Dank's employment and expressing confidence no rules were broken.
"The Manly Warringah Sea Eagles employed Stephen Dank in an official capacity as a consultant between 2006 and 2010," it said.
"During that time, we never had any concerns.
"We always complied with all anti-doping protocols of the WADA Code and the NRL.
"The club will make no further comment."
Dank has also undertaken consultancy work at NRL club Cronulla as well as with the Gold Coast Suns.
