What are the Enhanced Games - or the 'Olympics on steroids'?
The inaugural Enhanced Games will feature dozens of elite athletes using performance-enhancing drugs to try and break world records in track, weightlifting and swimming.
Some $25m (£18.6m) in prize money is up for grabs - with world records in certain events paying a $1m (£740,000) bonus.
The drugs they use must be legal, and approved by the Federal Drug Administration.
But substances like testosterone and human growth hormone - banned by the World Anti Doping Agency - are not only celebrated here, they're encouraged and for sale.
