Mr Slezak returned an Adverse Analytical Finding (AAF) from an out-of-competition doping control test on 12 December 2017.

His sample was analysed at the Australian Sports Drug Testing Laboratory, part of the National Measurement Institute, which detected the presence of Prohibited Substances:

  • 4-chloro-3a-hydroxyandrost-4-en-17-one (metabolite of Clostebol);
  • Oxandrolone and its metabolites (17b-methyl-17a-hydroxy-2-oxa-5a-androstan-3-one; and 17a-hydroxymethyl-17b-methyl-18-nor-2-oxa-5a-androst-13-en-3-one); and
  • 16b-hydroxystanozolol and 17-epi-stanozolol-N-glucuronide (metabolites of Stanozolol). 

In addition to the AAF:

  • On and/or before 12 December 2017, Mr Slezak used Prohibited Substances, namely, Clostebol and/or Oxandrolone and/or Stanozolol;
  • On and/or after 6 July 2017, he used or attempted to use Prohibited Substances, namely Thymosin Beta 4 and/or Mechano Growth Factor;
  • On and/or after 14 July 2017, he possessed Prohibited Substances, namely Thymosin Beta 4 and/or Mechano Growth Factor;
  • On and/or after 26 July 2017, he used or attempted to use Prohibited Substances, namely Ipamorelin and/or CJC-1295 and/or Mechano Growth Factor and/orThymosin Beta 4;
  • On and/or after 26 July 2017, he possessed Prohibited Substances, namely Ipamorelin and/or CJC-1295 and/or Mechano Growth Factor and/or Thymosin Beta 4;
  • On and/or after 28 August 2017, he attempted to use Prohibited Substances, namely GHRP-6 and/or Ipamorelin and/or Long R3 IGF-1 and/or CJC-1295 and/or Mechano Growth Factor and/or Thymosin Beta 4;
  • On and/or after 28 August 2017, he possessed Prohibited Substances, namely GHRP-6 and/or Ipamorelin and/or Long R3 IGF-1 and/or CJC-1295 and/or Mechano Growth Factor and/or Thymosin Beta 4;

  • On and/or after 9 September 2017, he possessed Prohibited Substances, namely Thymosin Beta 4 and/or Mechano Growth Factor;
  • On and/or after 12 November 2017, he attempted to use Prohibited Substances, namely GHRP-6 and/or CJC-1295 and/or Mechano Growth Factor and/or Thymosin Beta 4; and
  • On and/or after 13 November 2017, he possessed Prohibited Substances, namely  GHRP-6 and/or CJC-1295 and/or Mechano Growth Factor and/or Thymosin Beta 4.

The substances Clostebol, Oxandrolone and Stanozolol are listed under Class S1.1a (Exogenous Anabolic Androgenic Steroids) of the World Anti-Doping Code - International Standard - Prohibited List 2017 (2017 Prohibited List).

Thymosin Beta 4, Mechano Growth Factor and Long R3 IGF-1  are prohibited at all times under Class S2 (Peptide Hormones, Growth Factors, Related Substances and Mimetics – other substances with similar chemical structure or similar biological effects) of the Prohibited List 2017.

GHRP-6, Ipamorelin and CJC-1295 are prohibited at all times under Class S2.5 (Peptide Hormones, Growth Factors, Related Substances and Mimetics – Growth Hormone and its releasing factors) of the 2017 Prohibited List.

All of the above substances are prohibited both in and out-of-competition.

Mr Slezak is ineligible to participate in any sports that have adopted a World Anti-Doping Code compliant anti-doping policy until 12 December 2021.

Additional information on the prohibited substance

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. Liver disease and infertility can also result from the use of these agents.

There are a number of health concerns for Class S2 Peptide Hormones, Growth Factors and Related Substances. Long-term studies in the use of growth hormone releasing peptides (GHRPs) have not been performed as the majority available on the internet have not been approved for human use. However, given that these peptides are used to release growth hormone, excessive amounts in healthy people may cause side effects like those observed in people with acromegaly, such as cardiovascular disease states.
