In one the latest incidents, a pupil at King Edward VII High School in Johannesburg was caught injecting himself with steroids earlier this month. Another pupil at the school admitted to using steroids in a tablet form.
Meanwhile, the owner of an online fitness company this week broke down when confronted about allegations that he sold prescription drugs aimed at weight loss and performance enhancement on the internet.
The Medicines Control Council said this week it had asked police to investigate Johannesburg sport supplement supplier Alan Wakelin.
In e-mails to customers, which the Sunday Times has seen, Wakelin says he can obtain any pharmaceutical product, irrespective of the schedule, including Concerta and Ritalin. Both are Schedule 6 drugs and contain the stimulant methylphenidate, which is prohibited in competition by the World Anti-Doping Agency.
