The Athletics Integrity Unit announced on Friday that South African race-walker Lebogang Shange had tested positive for a prohibited substance known as trenbolone.
The 29-year-old has been issued a ‘notice of allegation’ and provisionally suspended from participating in any athletics-related competition or activity, according to the Athletics Integrity Unit, which was founded by the International Association of Athletics Federations (IAAF) in 2017.
However, a final decision will be made at a hearing conducted under the IAAF Anti-Doping Rules or the Integrity Code of Conduct, the Unit said on their website.
Shange is on the list of Athletics South Africa’s (ASA) squad preparing for the 2020 Olympic Games in Tokyo, Japan.
Trenbolone is a steroid used in veterinary medicine to improve the profitability of livestock by boosting muscle growth and appetite.
Shange competed at the 2016 Olympic Games in Rio and also at the 2017 IAAF World Championships in London.
