What it feels like to be an Enhanced Games athlete

"If I wanted a doctor's opinion on whether or not people's health is at risk, I would go to a doctor. Not Kieren Perkins." It takes a lot to push James Magnussen, the three-time Olympic medallist and two-time world champion in the 100m freestyle, out of his naturally relaxed and jovial demeanour. But that’s what…

The second act of Patrick Arnold: the chemist who designed The Clear, then invented the ketone supplement industry

In 2011, a University of South Florida researcher called Dominic D'Agostino came to Patrick Arnold with a request. He needed a molecule synthesised.
