At a warehouse used by the coach of disgraced sprinters Kostas Kederis and Ekaterina Thanou, anabolic steroids have been discovered by Greek medical chiefs according to Greece’s National Organisation of Medicines.

“The supplements included materials that do not have a distribution license,” read a statement from the agency.

More than 1,000 ‘units’ of food supplements that were exposed included the stimulant ephedrine as their main ingredient.
