Astarloza denied using EPO, saying that it was "sporting suicide" to use illegal performance-enhancing drugs. On 15 May 2010, he was formally handed a two-year ban by the Spanish Cycling Federation. Astarloza continually claimed his innocence, and Euskaltel-Euskadi stated that they would rehire him once the ban ended. He indeed rejoined the Basque team in August 2011, at the Vuelta a Burgos.
