After an evidentiary hearing on November 28, 2022, where both Ruiz-Gutierrez and USADA were provided a full opportunity to present their cases and witnesses to the independent arbitrator, the arbitrator imposed a four-year sanction on Ruiz-Gutierrez for his anti-doping rule violations.

Ruiz-Gutierrez, 47, tested positive for dexamethasone, phentermine, 19-noretiocholanolone (19-NE), 19-norandrosterone (19-NA), and an anabolic agent as the result of an in-competition urine sample collected at the Tour of South Florida on February 5, 2022.

His urine sample was analyzed using a specialized test known as Isotope Ratio Mass Spectrometry (IRMS), that unequivocally differentiates between anabolic androgenic steroids (AAS) naturally produced by the body and AAS of synthetic origin—in this case, testosterone and/or its precursors. All AAS are Non-Specified Substances in the class of Anabolic Agents and are prohibited at all times.


  • Dexamethasone is a Specified Substance in the class of Glucocorticoids and is prohibited in-competition when administered by specific routes
  • Phentermine is a Non-Specified Substance in the class of Stimulants and is prohibited in-competition
  • 19-norsteroids, including 19-NE and 19-NA, are Non-Specified Substances in the class of Anabolic Agents and prohibited at all times

These substances are prohibited under the USADA Protocol for Olympic and Paralympic Movement Testing, the United States Olympic and Paralympic Committee National Anti-Doping Policy, and the International Cycling Union Anti-Doping Rules, all of which have adopted the World Anti-Doping Code and the World Anti-Doping Agency Prohibited List.

Ruiz-Gutierrez’s four-year period of ineligibility began on December 22, 2022, the date his sanction was imposed. In addition, Ruiz-Gutierrez has been disqualified from all competitive results obtained on and subsequent to February 5, 2022, the date his positive sample was collected, including forfeiture of any medals, points and prizes.
