The trouble with Ostarine: Jimmy Wallhead’s
16th March 2018

The National Rugby League (NRL) has today provisionally suspended Parramatta Eels player Michael Jennings under the NRL’s Anti-Doping Policy. The Provisional Suspension Notice asserts that Mr Jennings returned a positive A-sample for LGD-4033 (Ligandrol) and its metabolite Di-hydroxy-LGD-4033, and also Ibutamoren and its metabolites Desbenzyl Ibutamoren and OH Ibutamoren.
Each of those substances are prohibited by the World Anti-Doping Agency (WADA) and the NRL’s Anti-Doping Policy. Mr Jennings was tested by Sport Integrity Australia (SIA) on 21 September 2020 with the positive result received by SIA on 9 October 2020.
Mr Jennings is prohibited from participating in any WADA compliant sport, including rugby league, while the provisional suspension is in place. Under the Anti-Doping Policy, Mr Jennings now has the opportunity to have his B-sample analysed. The NRL has spoken with Jennings and advised him of the support services available to him.
