Wrestler receives sanction

  • Doping Violation Update

Sport Integrity Australia acknowledges the decision of Wrestling Australia to impose a four-year ban on athlete David Jae Wook Ryu for the Presence of a Metabolite/s of a Prohibited Substance/s, the Use of a Prohibited Substance/s, and the Possession of a Prohibited Substance/s.

Mr Ryu returned an Adverse Analytical Finding (AAF) from an Out-of-Competition doping control test at a training camp at the Australian Institute of Sport on 26 April 2022.

Mr Ryu’s sample was analysed at the Australian Sports Drug Testing Laboratory, part of the National Measurement Institute, and the presence of a Metabolite/s of a Prohibited Substance, namely Di-hydroxy LGD-4033 (metabolite of LGD-4033 (Ligandrol)) and 4a-chloro-17b-hydroxymethyl-17a-methyl-18-nor-5a-androst-13-en-3a-ol and 4-chloro-17b-hydroxymethyl-17a-methyl-18-nor-5b-androsta-1,13-dien-3a-ol (metabolites of Dehydrochloromethyltestosterone (DHCMT)), were detected.

It was determined that on and/or before 26 April 2022 Mr Ryu used a Prohibited Substance/s, namely LGD-4033 (Ligandrol) and Dehydrochloromethyltestosterone (DHCMT).

It was also determined that from on and/or around 19 July 2021 to on and/or around 31 December 2021 Mr Ryu possessed LGD-4033 (Ligandrol), and from on and/or around 4 May 2022 to on and/or around 9 September 2022, he possessed Metandienone (Dianabol).

About the Substances 

Metandienone and Dehydrochloromethyltestosterone are banned under class S1.1 Anabolic Androgenic Steroids of the World Anti-Doping Agency’s 2021 and 2022 Prohibited Lists as Non-Specified Substances and are prohibited at all times. 

LGD-4033 (Ligandrol) is listed under class S1.2 (Anabolic Agents – Other Anabolic Agents) of the 2021 and 2022 Prohibited Lists as a Non-Specified Substance and is prohibited at all times.

Wrestling Australia thereby imposed a four-year ban on Mr Ryu commencing on 31 December 2021. 

Mr Ryu is ineligible to participate in any sports that have adopted a World Anti-Doping Code compliant anti-doping policy until 31 December 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 

Anabolic agents pose many threats to an athlete’s health and some side effects may include an increase in blood pressure and cholesterol levels which can lead to heart disease. The side effects of using Metandienone and Dehydrochloromethyltestosterone include damage to the liver, heart and reproductive system. 

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.
