During the 2009 season, Landaluze tested positive for the use of Continuous erythropoietin receptor activator (CERA) at the 2009 Critérium du Dauphiné Libéré.

However his win was clouded in controversy as it was soon announced he had tested positive for abnormally high testosterone and was suspended from racing until his case was heard out.

In 2006, however, he was cleared to return to racing after he showed that the lab conducting tests committed procedural errors.

New revisions to the WADA Code would suggest that Landaluze would have lost his case under the new rules.

Iñigo Landaluze was provisionally suspended by the Union Cycliste Internationale on July 17, 2009 after testing positive for the banned blood booster CERA at the 2009 Critérium du Dauphiné Libéré.
