Today the United States Anti-Doping Agency, the UFC’s anti doping policy administrator, announced that Felipe Olivieri has been handed a 2 year suspension after testing positive for a prohibited substance in an out-of-competition urine test on January 11, 2016. The test revealed the presence of 5α-tetrahydromethyltestosterone and 5β–tetrahydromethyltestosterone, which are metabolites of methyltestosterone.
Methyltestosterone is banned at all times (both in and out of competition) under the UFC / USADA anti doping policy. Olivieri disputed the findings and proceeded to arbitration.
An independent Arbitrator for McLaren Global Sports Solutions, Inc. adjudicated the matter and handed Olivieri a 2 year ban.
