Ex-cycling doctor Richard Freeman has been found guilty at a medical tribunal of ordering banned testosterone for an unnamed cyclist.
Freeman is the former chief doctor for British Cycling and Team SKY, working for them between 2009 and 2017.
He was found culpable at the Medical Practitioners Tribunal Service in Manchester of 'knowing or believing' that substance Testogel was to be administered to an athlete to improve their athletic performance.
Neil Dalton, chair of the MPTS, told Freeman that "The motive for your action was to conceal a conduct.”
Freeman had already admitted 18 of 22 charges against him but had denied ordering testosterone knowing it would be used for the purpose of doping.
He had claimed in testimony that the substance was to treat former British Cycling and Team SKY coach Shane Sutton's erectile dysfunction, an assertion Sutton denied.
Freeman was the doctor for British Cycling and Team SKY at a time of great success for the sport in the UK; victories included Bradley Wiggins' Tour de France win in 2012 and topping the medals tables at the 2012 and 2016 Olympic Games. No British rider involved has ever been found guilty of an anti-doping violation.
Freeman will face further sittings of the tribunal to determine whether he should lose his doctor's licence.
