Greek swimmer Kristian Gkolomeev has bettered a world record while on drugs, becoming a millionaire in less than 21 seconds.
The four-time Olympian is the second confirmed athlete for Enhanced Games, a sports event with no drug testing in Las Vegas next May.
Gkolomeev followed Australia's James Magnussen in joining Enhanced Games, which promises $US1 million to any swimmer besting the men's 50m freestyle world record.
