Its so easy to avoid positive tests. Gatlin knows this well. Like Robinson, I know that if I say more it will jeopardize my athletic career.
"Darrell Robinson, a former teammate of Griffith Joyner, claimed that he sold her 10 c.c. of HGH for $2,000 in 1988. He said Joyner told him: "if you want to make $1 million, you've got to invest some thousands."[15] Robinson also claimed to receive steroids from coach Bob Kersee, and said he saw Carl Lewis inject himself with drugs he believed to be testosterone.[17] Robinson never provided any evidence for his allegations and was shunned by the athletics community, leading to the premature end of his career.
Griffith Joyner retired from competitive track and field after her Olympic triumph in 1988.[18] She was repeatedly tested during competition, and she passed all of these drug tests. Griffith Joyner made public her decision to retire from Olympic competition one week after it was announced that random out-of-competition drug testing would be instituted during the 1989 season.[19][20]
After her death in 1998, Prince Alexandre de Merode, the Chairman of the International Olympic Committee's medical commission, claimed that Joyner was singled out for extra, rigorous drug testing during the 1988 Olympic Games because of rumors of steroid use. De Merode told The New York Times that Manfred Donike, who was at that time considered to be the foremost expert on drugs and sports, failed to discover any banned substances during that testing.[21] De Merode later said:
"We performed all possible and imaginable analyses on her. We never found anything. There should not be the slightest suspicion."[22]
