Norwegian sprinter Aham Okeke has received a lifetime ban from competition after confessing to using the male sex hormone testosterone, anti-doping officials said on Monday.
The six-times national 100 metres champion said he had received a prescription for the tablets from a doctor unaffiliated with Norwegian sports bodies.
Okeke, 37, tested positive for testosterone in an out-of-competition control in Gothenburg, Sweden, on July 7.
It was the third time the Nigerian-born Okeke had been caught using a banned substance.
