'Mad Max' Actor Richard Norton Died After Injection of Unapproved Peptides, Coroner Finds

Richard Norton, an Australian actor and martial artist best known for his role in "Mad Max: Fury Road," died on March 30, 2025, at Melbourne's Alfred Hospital in Australia. He was 75 years old. An Australian coroner investigated his death and found that an injection of unapproved peptides — small chemical compounds sometimes used in experimental medicine — caused a deadly allergic reaction. The coroner's findings were officially dated October 28, 2025.

Coroner David Ryan concluded that Norton received an injection of a peptide mixture called CJC1295/ipamorelin. This injection triggered a condition called anaphylaxis, which is a severe and life-threatening allergic reaction. Anaphylaxis can cause blood pressure to drop suddenly and can narrow a person's airways, making it very hard to breathe. The coroner also found that Norton had asthma and a heart muscle disease called hypertrophic cardiomyopathy, both of which made his condition worse.

Hypertrophic cardiomyopathy is a disease that causes the heart muscle to become too thick. When the muscle is too thick, the heart has trouble pumping blood the way it should, according to the Mayo Clinic. Norton's combination of the allergic reaction, asthma, and this heart condition all played a role in his death. Doctors say these kinds of overlapping health problems can make a medical emergency much harder to survive.

Norton had been seeking treatment for several health problems before he died. He was experiencing fatigue, shoulder pain, and muscle loss, according to the coroner's report. His doctor talked to him about the experimental nature of the treatment and its risks, and Norton signed a form saying he understood that anaphylaxis was a possible danger. Still, he chose to move forward with the injections.

On March 28, 2025, Norton told a nurse that he had been injecting himself with twice the dose his doctor had prescribed. That evening, after another injection, he felt hot and flushed and then collapsed. His wife began performing CPR right away, and paramedics rushed him to the hospital. He died two days later on March 30.

Coroner Ryan made an important recommendation after completing his investigation. He urged Australia's Therapeutic Goods Administration — the government agency that oversees medicines — to look more carefully at the risks and possible benefits of these peptides. He also suggested that officials consider tighter restrictions, such as limiting the use of these substances to clinical trials or other carefully monitored settings. This would help make sure fewer people are harmed by unapproved treatments.

Norton had a long and impressive career in film and television that spanned more than 80 movies, according to ABC. He worked as an actor, a stunt performer, and a fight choreographer — someone who designs and plans the fighting scenes in movies and TV shows. He appeared alongside Chuck Norris in "The Octagon" in 1980 and later worked as a fight coordinator on the TV series "Walker, Texas Ranger," even appearing in several episodes himself.

One of Norton's most famous roles was playing the Prime Imperator in the 2015 blockbuster "Mad Max: Fury Road." He also personally trained actress Charlize Theron for her role in that film. In 2016, Norton worked with Margot Robbie and Will Smith on the superhero film "Suicide Squad," showing just how wide his skills and connections in Hollywood were.

After Norton's death, his longtime friend Chuck Norris honored him with a heartfelt message on Instagram on March 30, 2025. "Richard, you made me not only a better martial artist but a better person," Norris wrote, calling Norton his "dear friend and brother." Norris himself passed away nearly a year later, on March 19, 2026. Norton's wife, Judy Green, also shared a message of grief on his Instagram account, writing, "I am numb and devastated, I have no words I have lost my everything."

Norton's death is drawing new attention to the growing use of unapproved peptides as medical treatments. In the United States, Health Secretary Robert F. Kennedy Jr. has been pushing to allow more people access to certain unapproved peptides, which has sparked debate among doctors and health experts. The findings from Norton's case are a reminder that experimental treatments can carry serious risks, even when a person is aware of those dangers and chooses to accept them.
