ACT Brumbies players have been warned that over-the-counter products may contain banned substances, and the club has its supplements in a locked cabinet to protect the rugby program's integrity.
Drug testers landed on the Brumbies' doorstep on Tuesday, getting samples from almost one third of the playing squad and testing high-performance staff for illicit drugs.
It is part of the Australian Rugby Union's fight against drugs and the Brumbies are taking extra steps to ensure no lines are blurred with their nutrition and supplements.
Players are tested for performance-enhancing substances, while coaching staff are tested for illicit drugs.
Brumbies coach Stephen Larkham has spoken to the players about taking extra precautions in the wake of the Essendon scandal, which has rocked the AFL for three years.
"We've spoken at length with the players, the ARU and RUPA have given us presentations and the players have done an online course," Larkham said.
"Punishments have been ramped up this year, if you test positive it's a four-year ban. The boys are all aware of the dangers of anything they put in their body.
"We've warned them that over-the-counter products might contain banned substances and they do have to be absolutely diligent with every supplement and product that they put in their mouths."
The ARU has ramped up its anti-doping policy in recent seasons, extending its illicit drug testing protocol to Super Rugby coaches and high-performance staff.
Drug education is part of every Super Rugby pre-season, put it hits home even more following the Essendon drama that led to 34 past and present players being banned from the sport for 12 months following a Court of Arbitration for Sport hearing.
Most sporting clubs use some form of protein and recovery shakes as well as vitamins, and the Brumbies have any supplements locked away with only a limited number of staff having access.
"The staff have had a few tests as well, we went through the procedure and all the boys know what's coming and understand the information," Larkham said.
The Brumbies will play their first pre-season trial against the NSW Waratahs in Wagga Wagga on Saturday.
Larkham is set to rest a host of Wallabies, including co-captains Stephen Moore and Christian Lealiifano, as well as Scott Fardy and David Pocock.
Matt Toomua will take the chief playmaking role and is a candidate to lead the team, with Jarred Butler looming as another option.
Argentinian scrumhalf Tomas Cubelli will make his Brumbies debut while the rest of the squad will get a chance to impress and stake their claim for Super Rugby selection.
"It will be good just to see our game in action this weekend. We've changed a few things in our game and it's a good chance to see them operate under pressure," Lealiifano said.
"It's a crucial time for preparation leading into round one. We want to be under pressure against a quality team, it's going to be tough but it will be good.
"I've got a slight calf [injury], but I've trained all week so it's just going to be touch and go."
Flanker Jordan Smiler was adamant the squad had plenty of capable leaders even if Lealiifano and Moore were not on the field.
"If they aren't there, we've got plenty of guys to put their hands up if something is going wrong," Smiler said.
"If there's something I think needs to be done, I'm not going to shy away and keep my mouth shut. Obviously I'll do what's best for the team."
