Former British Cycling and Team Sky doctor Richard Freeman will face accusations he ordered testosterone to enhance the performance of an athlete when a tribunal into his conduct starts in Manchester tomorrow.
Freeman, who began working for both organisations in 2009, was accused after 30 sachets of testogel, which is banned by the World Anti-Doping Agency (WADA), were posted to British Cycling's headquarters in 2011.
This was a year before the Olympic and Paralympic Games in London where Great Britain won 12 cycling medals including eight golds.
Freeman claimed the order was placed in error, but an investigation carried out by the General Medical Council (GMC) has alleged that this explanation was dishonest.
Freeman also told UK Anti-Doping (UKAD) investigators that the testogel had been ordered for a "non-athlete member of staff" but the GMC has also concluded that this was a lie.
As a result, the GMC brought a misconduct case against Freeman which is due to start at Manchester's St James' Buildings tomorrow.
According to the British newspaper The Daily Mail, Freeman will be quizzed on who he ordered the testogel for and whether he ordered it for staff members without their knowledge.
The newspaper claims staff from both British Cycling and Team Sky will be called as witnesses at the tribunal, to confirm if they were aware Freeman had ordered medication for them.
If they deny knowledge, it will spark further questions over who the drugs were for.
In a statement issued last month, the Medical Practitioners Tribunal Service revealed details of what the tribunal will cover.
"The tribunal will further inquire into the allegation that, when team doctor for athletes at the British Cycling Federation and Tour Racing/Team Sky, Dr Freeman inappropriately provided medical treatment that did not constitute first aid to non–athlete members of staff," it read.
"It is further alleged that Dr Freeman failed to inform three patients' GPs of medication prescribed and reasons for prescribing.
"The tribunal will further inquire into the allegation that, in his role as team doctor for athletes at the British Cycling Federation and Tour Racing/Team Sky, Dr Freeman failed to maintain an adequate record management system.
"It is further alleged that his management of prescription-only medication was inappropriate."
Freeman resigned from his post in 2017, citing stress caused by the investigation.
He also did not provide evidence to a Parliamentary Select Committee hearing in March of that year, blaming poor health.
Any new evidence that emerges from the tribunal could spark a fresh UKAD investigation, which could lead to Freeman being charged with an anti-doping rule violation if the evidence warrants it.
The testosterone case is not the only controversial case to have emerged involving Freeman.
He was accused of failing to keep adequate medical records after the mysterious jiffy bag saga surrounding Olympic and Tour de France champion Sir Bradley Wiggins.
In 2016 it emerged a mysterious package had been mailed to Sir Bradley at the Critérium du Dauphiné in 2011.
Freeman claimed the package contained the legal decongestant flumicil, although neither he or Team Sky could prove it after his laptop containing medical records was stolen.
In December, broadcast giant Sky announced it will end its involvement in cycling at the end of the 2019 season, saying it was "the right time" to leave.
To date the team has registered 322 total victories, including eight Grand Tours, 52 other stage races and 25 one-day races.
