Jamaica's Commonwealth Games 200m bronze medallist Jason Livermore on Monday testified that he declared the medication which contained the banned substances, for which he returned a positive test in December 2016.
Livermore made the disclosure during Monday's opening day of his drug hearing before the Kent Gammon-chaired three-member Independent Anti-Doping Disciplinary Panel at the Jamaica Conference Centre.
29-year-old Livermore, who was represented by his manager Lorenzo Sandford, was advised by the Jamaica Anti-Doping Commission (JADCO) of his doping violation for metabolites of clomiphene and mestorolone, in February this year, said the medications were for a "life threatening" situation.
Checks by RJR Sports revealed that clomiphene is an infertility drug, while mestorolone,is an anabolic steroid often used for athletic and muscle mass enhancement.
The former Calabar sprinter, who also won the 4x100 relay gold at the Commonwealth Games in 2014, said he was considering life after track and field where he wants to have a family, hence the treatment was necessary.
JADCO's new attorney Judith Clarke pressed home the fact that Livermore did not have a Therputic Use Exemption (TUE), permitting the use of the banned substances. Six other witnesses took the stand including Livermore's coach Michael Clarke of the Akan Track Club.
The other five from JADCO included outgoing Executive Director Carey Brown, two doping control officers and two chaperones.
The hearing for Livermore, who also helped Jamaica win the sprint relay gold at the 2014 Commonwealth Game, is set to resume on Monday, September 18, which his doctor is expected to take the stand.
The sprinter with personal best times of 10.03 and 20.13 seconds over 100m and 200m respectively, competed in the half lap event at the 2013 Moscow World Championships.
