Dublin doctor is man behind sensational top-level sport doping claims
The Dublin doctor at the centre of the latest doping scandal has denied that he has prescribed banned treatment to sports stars.
Dr Mark Bonar, who studied at UCD, is also facing proceedings over alleged misconduct during his treatment of a cancer patient and does not have a licence to practise in the UK.
The self-professed "celebrity doctor to the stars" was caught on film by undercover reporters bragging that he had prescribed performance-enhancing drugs to 150 professional athletes.
However, he took to Twitter last night to hit out at an article in The Sunday Times newspaper following their investigation which he said was "false and misleading":
The @SundayTimesNews allegations are false and very misleading. I have never had a relationship with any premier football club or player.— Dr Mark S. Bonar (@ZenGrifter) April 3, 2016
I have never prescribed Androgen therapy for the purpose of performance enhancement.. I treat symptomatic men with low Test levels— Dr Mark S. Bonar (@ZenGrifter) April 3, 2016
According to General Medical Council (GMC) records, Dr Bonar is "registered without a licence to practise". This means that he is still a registered doctor but cannot carry out medical work.
The GMC has also attached a number of conditions to the 38-year-old, including that he must inform them if he takes up employment outside of the UK.
From next Monday, he faces five days of a Medical Practitioners Tribunal that will probe allegations of misconduct relating to his treatment of a cancer patient between December 2013 and January 2014.
It is claimed that he failed to inform a woman with cancer that there was no treatment that would cure her and that he continued to administer a nutrition treatment that was not 'clinically indicated'.
It is also alleged that he failed to work with colleagues in the interests of the woman, failed to gain her informed consent, and failed to manage adequate medical records or seek palliative care for her.
A previous hearing into the same case, which was held in December 2015, heard the Dr Bonar continued to charge the woman for "unconventional" care, despite being advised that she needed palliative care after a scan had shown her cancer had spread.
It was claimed that neither Dr Bonar, nor the other doctor involved in her care revealed the content of the scans.
The woman passed away in 2014, aged 46.
Dr Bonar was secretly filmed and recorded revealing that he had prescribed performance enhancers to athletes including Premier League footballers.
There was no evidence that sports stars received banned treatment from the doctor and the sports clubs named have denied the allegations.
Dr Bonar, whose private treatment rooms were based in the Omniya clinic in Knightsbridge in London, leads a lavish lifestyle in the UK.
Pictures posted to his social media feed in the past two years included snaps of a trip to Dubai, a day at the Ascot racecourse and a luxury Mercedes car – as well as a picture of his new Louis Vuitton shoes.
In his biography penned to coincide with the launch of his new practise based in the Omniya clinic – the Ultra Wellness Clinic – he is described as a "number one choice for many 'A-Lister' celebrities".
Just last month, Dr Bonar registered as a company director of a firm called Androgenix Pharmaceuticals Ltd. On the company's website the firm is described as "innovators in testosterone replacement therapy".
