Westra admits using tramadol and caffeine as performance enhancers

After it emerged last week that he had used Therapeutic Use Exemptions (TUEs) to enable him to take cortisone injections, Lieuwe Westra has admitted to using the painkiller tramadol and caffeine pills as performance enhancing aids. The revelations come from Westra’s new autobiography, 'The Beast', which is due to be released on Tuesday.
