Rugby league player receives sanction

22 April 2020

The Australian Sports Anti-Doping Authority (ASADA) acknowledges the decision of the NSW Rugby League (NSWRL) to impose a four-year ban on athlete Andrew Diomei for the presence of a prohibited substance and the metabolites of prohibited substances and the use of prohibited substances.

Mr Diomei returned an Adverse Analytical Finding (AAF) from an in-competition doping control test on 11 August 2018.

His sample was analysed at the Australian Sports Drug Testing Laboratory, part of the National Measurement Institute, which detected the presence of 19-Norandrosterone and 19-Noretiocholanolone (metabolites of Nandrolone, Norandrostenedione or Norandrostenediol); and Boldenone and its metabolite.

It was determined that on/and or before 11 August 2018 Mr Diomei used Nandrolone, Norandrostenedione or Norandrostenediol; and Boldenone.

The NSWRL imposed a four-year ban on Mr Diomei commencing on 27 August 2018.

Mr Diomei is ineligible to participate in any sports that have adopted a World Anti-Doping Code compliant anti-doping policy until 27 August 2022. He is also not permitted to compete in a non-signatory professional league, or event organised by a non-signatory International or National level event organisation.

Additional information on the prohibited substance

Nandrolone, Norandrostenedione and Norandrostenediol

The substances 19-Norandrosterone and 19-Noretiocholanolone (metabolites of Nandrolone, Norandrostenedione or Norandrostenediol) are Class S1.1b (Endogenous Anabolic Androgenic Steroids) substances under the World Anti-Doping Code Prohibited List 2018 and are prohibited at all times.

Nandrolone, Norandrostenedione and Norandrostenediol are listed under Schedule 4 of the Poisons Standard and are therefore regulated poisons. Possession without authority is an offence.

Some of the general side effects of Nandrolone include swelling of ankles or feet, increased blood pressure, rash and increased or decreased sexual desire. Nandrolone also shows specific side effects in males, for example enlargement of the breast, difficulty to urinate due to growth of the prostate, reduction in sperm count, testicular atrophy and impotence. In females, Nandrolone could cause changes of the voice, which may be long-lasting or permanent, increased body or facial hair, and masculinisation.

Nandrolone, Norandrostenedione or Norandrostenediol are prohibited imports under the Customs (Prohibited Imports) Regulation 1956. Importation into Australia without a permit is an offence.


Under Class S1.1.b of the World Anti-Doping Code Prohibited List 2018, Boldenone is prohibited both in and out-of-competition.

Boldenone was developed for use in veterinary medicine and is not approved for human use. The side effects include permanent liver damage, heart problems, aggressiveness and infertility.
