Sport Integrity Australia acknowledges that Rugby Australia has imposed a two year, and nine months ban on athlete Corbin Kiernan for Presence of a Prohibited Substance, Use and/or Attempted Use of a Prohibited Substance/s and Possession of a Prohibited Substance/s.
Mr Kiernan, a Rugby Union player contracted to Bond University in the Queensland Premier Rugby Competition at the time, returned an Adverse Analytical Finding (AAF) from an Out-of-Competition doping control test on 19 April 2022.
Mr Kiernan’s sample was analysed at the Australian Sports Drug Testing Laboratory, part of the National Measurement Institute, and the presence of Ibutamoren was detected.
The substance Ibutamoren is listed under Class S2 (Peptide Hormones, Growth Factors, Related Substances and Mimetics) under the World Anti-Doping Code – International Standard – Prohibited List – 2022 (Prohibited List 2022). The substance Ibutamoren is a Non-Specified Substance and is prohibited at all times.
It was determined that on 23 February 2022 to on and/or around 4 May 2022 Mr Kiernan Used and Possessed the Prohibited Substance Ibutamoren.
It was also determined that on and/or around 23 February 2022 to on and/or around 4 May 2022 Mr Kiernan Used and/or Attempted to Use and Possessed the Prohibited Substance BPC-157.
The substance BPC-157 is listed under Class S0 (Non-Approved Substances) under the Prohibited List 2022. The substance BPC-157 is a Specified Substance and is prohibited at all times.
Both Prohibited Substances were prescribed to Mr Kiernan by a medical practitioner and dispensed at a pharmacy.
Mr Kiernan’s period of Ineligibility was also suspended for a period of 3 months for Substantial Assistance. Rugby Australia thereby imposed a two year, and nine months ban on Mr Kiernan commencing on 19 April 2022.
Mr Kiernan is ineligible to participate in any sports that have adopted a World Anti-Doping Code compliant anti-doping policy until 19 January 2025.
He is also not permitted to compete in a non-Signatory professional league or Event organised by a non-Signatory International Event organisation or a non-Signatory national-level event organisation.
Additional information on the Prohibited Substances
Ibutamoren, also known as MK 677 and Nutrobal, is a substance that increases the levels of Human Growth Hormone (HGH) in the body. It is illegal to possess ibutamoren without authority.
While it’s marketed online as a substance to ‘build muscle’, ibutamoren is technically considered a poison, is banned in sport and has a range of dangerous side effects.
Reported side effects include increased appetite, swelling, anxiety, numbness and muscle pain. It also causes bone mineral density to decrease and causes increased fasting blood glucose and decreased insulin sensitivity.
BPC-157 is an experimental peptide. Manufacturers of the substance claim it improves joint healing; however, this substance is not approved for human clinical use.
Sport Integrity Australia recommends athletes check substances and medications before taking them and to follow our advice on sports supplements.
The Sport Integrity app provides a resource to both check substances and medications. As well as information on how to find batch-tested supplements and see if a Therapeutic Use Exemption (TUE) is needed.
The Sport Integrity app is available for free on the App Store and Google Play.
