USADA announced today that Daniel “Jason” Sandor, of Romulus, Mich., an athlete in the sport of wheelchair rugby, has accepted a four-year period of ineligibility for an anti-doping rule violation after testing positive for multiple prohibited substances.
Sandor, 32, tested positive for ostarine (enobosarm) and di-hydroxy-LGD-4033, a metabolite of LGD-4033 (ligandrol), as the result of an out-of-competition urine sample collected on April 22, 2025. USADA notified Sandor of his positive test and immediately imposed a provisional suspension against him on May 12, 2025, barring him from competing until his case was resolved. Additionally, Sandor tested positive for ostarine, di-hydroxy-LGD-4033, and an anabolic agent as the result of a second out-of-competition urine sample collected on May 10, 2025. Sandor’s second 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. The IRMS analysis was consistent with the exogenous origin of testosterone and/or its metabolites in Sandor’s sample.
In its investigation, USADA determined that Sandor was using testosterone at the direction of a physician, although he lacked a valid Therapeutic Use Exemption (TUE). USADA’s investigation also revealed that Sandor had used RAD140 while he was using LGD-4033 and that both products contained ostarine, which was not listed on the products’ labels. Unlike testosterone, his use of these unapproved Selective Androgen Receptor Modulators (SARMs) was not at the direction of a physician.
Under the World Anti-Doping Code, Sandor’s two positive tests and use of RAD140 were considered a single violation and not multiple violations because he had not yet been notified of the first positive test at the time his second sample was collected on May 10, 2025.
Ostarine, LGD-4033, testosterone, and RAD140 are non–Specified Substances in the class of Anabolic Agents and are prohibited at all times under the USADA Protocol for Olympic and Paralympic Movement Testing, the United States Olympic and Paralympic Committee National Anti-Doping Policy, and the World Wheelchair Rugby Anti-Doping Rules, all of which have adopted the World Anti-Doping Code and the World Anti-Doping Agency Prohibited List.
Sandor requested a hearing before an independent arbitrator before he ultimately accepted a four-year sanction. His four-year period of ineligibility began on May 12, 2025, the date his provisional suspension was imposed. In addition, Sandor has been disqualified from all competitive results obtained on and subsequent to October 31, 2024, the date he began using the prohibited substances, including forfeiture of any medals, points and prizes. USADA did not apply aggravating circumstances in this case because, among other things, Sandor’s use of LGD-4033 and RAD140 occurred before he received anti-doping education, and his cooperation with the investigation resulted in USADA’s discovery of his RAD140 use.
In an effort to aid athletes, as well as support team members such as parents, coaches, and medical professionals in understanding the rules applicable to them, USADA provides comprehensive instruction on its website on the testing process and prohibited substances, how to file and update athlete Whereabouts, how to obtain permission to use a necessary medication, and the risks and dangers of taking supplements, as well as performance-enhancing and recreational drugs.
In addition, USADA manages a drug reference hotline, Global Drug Reference Online (GlobalDRO.com), conducts educational sessions with National Governing Bodies and their athletes, and distributes a multitude of educational materials, such as a supplement guide, a nutrition guide, a clean sport handbook, and periodic alerts and advisories.
USADA makes available a number of ways to report the abuse of performance-enhancing drugs in sport in an effort to protect clean athletes and promote clean competition.
