Rugby league player receives sanction

  • Doping Violation Update

Sport Integrity Australia acknowledges the decision of the NRL Anti-Doping Tribunal to sanction athlete James Segeyaro for the presence of a metabolite of a prohibited substance and the use of a prohibited substance.

Mr Segeyaro returned an Adverse Analytical Finding (AAF) from an out-of-competition doping control test on 3 September 2019.

His sample detected the presence of Di-Hydroxy LGD-4033 (metabolite of LGD-4033) and LGD-4033.

  • LGD-4033 is prohibited in and out-of-competition under the S1 Class of Anabolic Agents.
  • The NRL Anti-Doping Tribunal imposed a 20-month ban on Mr Segeyaro commencing on 3 October 2019.
  • Mr Segeyaro will be eligible to return to competition on 3 June 2021.

Additional information on the prohibited substance

LGD-4033, originally developed for the treatment of muscle wasting conditions such as aging, osteoporosis, muscular dystrophy and cancer, is promoted as a selective non-steroidal anabolic agent.

It is claimed to be a substance that induces muscle (and bone) growth without the side effects associated with steroid use. However, information on the safety of LGD-4033 is scarce due to a lack of medium and long-term clinical trials - hence the medium and long-term health impacts are unknown.

It should be noted that a number of Selective Androgen Receptor Modulators (SARMs) have associated health-risks, particularly for the heart and liver.
