James Magnussen didn’t just step back into the pool—he stepped into a different version of himself.
Two years after declaring he would “juice to the gills” for the highly controversial Enhanced Games. the Australian swimming star. now 35. has been transformed into something close to unrecognisable. Days before the inaugural event in Las Vegas. Magnussen has unveiled a hulking. shredded frame as anticipation builds around a competition that critics have already dubbed the “Steroid Olympics.”.
On Monday AEST, Magnussen is set to race the 50m and 100m freestyle events at the Games. The physical change is so dramatic that fans flooded social media with disbelief after seeing the new look. piling into the comments section with reactions ranging from admiration to outright jokes. One fan wrote, “Lesssgoo, absolutely shredded.” Another posted, “Shreddy McShredderson,” while a third added, “Half man, half abdominal muscle.”.
Even the caption stirred the reaction. In an Instagram post captioned “We know you’re watching – enjoy the show,” Magnussen showed off his chiselled physique as the debate around the Enhanced Games kept intensifying.
The story behind the body change has been part of Magnussen’s public journey for months. Last year. he first raised eyebrows when he bulked up to 114kg while attempting to break the 50m freestyle world record wearing a banned polyurethane supersuit. At the time. the retired Olympian admitted the sheer amount of muscle made him feel like he was “sinking” in the water.
He later shifted his training and body composition for the Enhanced Games, dropping 17 kilograms. The former world champion previously weighed 114 kilograms when he won silver at the London Olympics. and that earlier weight has become part of the comparison fans can’t stop making as they track how far he has gone since.
The Enhanced Games itself is what sits at the centre of the storm. Organisers are openly embracing substances banned in mainstream elite sport under medical oversight. and the format has divided the sporting world from the start. At the event. athletes are permitted to use performance enhancers—including testosterone. peptides. growth hormones and other banned drugs—provided they are approved by the US Food and Drug Administration.
Magnussen has confirmed he has been using a protocol involving testosterone and peptides under medical supervision for almost two years. The event allows athletes to use substances banned by the World Anti-Doping Agency. including testosterone. human growth hormone and EPO. provided they meet the approval requirement tied to the US Food and Drug Administration.
Supporters point to the money and the promise of safety documentation; critics see something far darker. Magnussen has said organisers needed to “get this perfect” amid scrutiny around the event’s safety concerns. He has also openly acknowledged the financial incentives at the Enhanced Games are far bigger than what he earned during his decorated professional swimming career.
The swimmer could earn hundreds of thousands of dollars if he wins his races. and world-record bonuses worth up to $US1million ($A1.4million) are also on offer. Magnussen’s own words made the stakes plain: “Me being the first athlete on board. we have to get this perfect.” He added. “It’s in everyone’s best interest for me. A. to swim fast. B. to prove that this process can be done safely and. C. to document that for everybody to see.”.
Those assurances are exactly where critics have pushed back hardest. In a joint statement. WADA and the International Olympic Committee condemned the Games as a “dangerous and irresponsible concept.” They warned that such substances can lead to serious long-term health consequences—“even death”—and said encouraging athletes to use them is “utterly irresponsible and immoral.”.
The event’s blueprint adds another layer to the confrontation. The Enhanced Games were founded by Australian entrepreneur Aron D’Souza. who has described the project as a pathway towards “super humanity – humans 2.0.” D’Souza also believes the competition could help drive a booming anti-ageing industry. saying: “Performance medicine is the road to anti-ageing; it’s the route to the fountain of youth.” He added. “Nothing will improve the productivity of our society more than preventing ageing.”.
The inaugural Enhanced Games will be held at a specially built arena inside Resorts World in Las Vegas. Alongside swimming, the programme includes athletics, weightlifting and strongman events.
For Magnussen. the controversy arrives with race day already locked in—50m and 100m freestyle under the Enhanced Games’ rules. with the world watching not just whether he can swim faster. but what it costs. what it risks. and whether the experiment will be allowed to define a future where “medical supervision” becomes the line between sport and something else entirely.
