• The Union Cycliste Internationale (UCI) has sanctioned Chilean Carlos Oyarzun with a four-year ban, over a year after he tested positive for FG-4592. The compound stimulates the production of erythropoietin (EPO) inside the body (endogenous). Unlike exogenous (externally administered) EPO, it is available in pill form and works in combatting anaemia by increasing an individual’s ability to produce red blood cells. As red blood cells contain iron, this helps combat anaemia, but red blood cells also carry oxygen around the body – specifically to the muscles. It is also understood that FG-4592 doesn’t raise blood pressure in the same way as EPO, reducing the risk of heart attacks due to ‘thickened’ blood. On 29 July last year, the UCI suspended the Androni Giocattoli-Sidermec Pro Continental team for 30 days, after rider Fabio Taborre reported an adverse analytical finding for FG-4592. In April last year, the French anti-doping agency (AFLD) confirmed that race-walker Bertrand Molinet had returned a positive test for FG-4592.
