UFC Athlete, Gleison Tibau Accepts Sanction for Anti-Doping Policy Violation

Gloves_posts-gleison-tibau-mma-ufcUSADA announced today that Janigleison Herculano Alves aka Gleison Tibau, of Rio Grande do Norte, Brazil, an athlete in the UFC, has received a 2-year sanction for an anti-doping policy violation.

Tibau, 32, tested positive for erythropoietin (EPO) following both out-of-competition and in-competition tests conducted on October 23, 2015 in Coconut Creek, Florida, and on November 7, 2015 in Sao Paulo, Brazil, respectively. EPO is a synthetic hormone used to stimulate the body’s production of red blood cells, thereby increasing oxygen transport and aerobic power, and is a prohibited substance in the class of Peptide Hormones, Growth Factors, Related Substances and Mimetics under the UFC Anti-Doping Policy.

Tibau’s period of ineligibility began on November 7, 2015, the date on which he last competed. In addition, Tibau has been disqualified from all competitive results obtained on and subsequent to October 23, 2015, the date on which his first positive sample was collected in violation of the UFC Anti-Doping Policy. As the regulatory body that sanctioned Mr. Tibau’s bout on November 7, 2015, the Comissao Atletica Brasileira de MMA (CABMMA) has recognized USADA’s sanction and, in accordance with the CABMMA Anti-Doping Policy, reversed the outcome of Mr. Tibau’s bout from a “win” to a “loss.”
