Richard Norton, a celebrated Australian actor and martial artist, tragically passed away at the age of 75 due to a heart attack that was linked to an overdose of unapproved peptides. This revelation comes from a coroner’s report released recently, detailing the events leading up to his untimely death in March 2025.
The report, submitted by Melbourne coroner David Ryan, indicated that Norton had been administering double the recommended dosage of peptides, specifically CJC1295 and Ipamorelin, to address health issues following shoulder surgery. Just two days before his death on March 30, 2025, he disclosed to a nurse that he was taking more than what had been prescribed, prompting a warning to adhere to the proper dosage.
Sadly, Norton’s death marks a significant case, as it is reportedly the first confirmed fatality in Australia associated with the use of unapproved peptide treatments. Peptides, small protein fragments promoted for various health benefits, have gained popularity through social media influencers but often lack regulatory approval.
In addition to his acting career, Norton was known for training Hollywood celebrities, including Ben Affleck and Scarlett Johansson, and serving as a stuntman for rock legends. The coroner’s report also criticized Dr. Jerzy Muchnicki, who prescribed the peptides, for not verifying Norton’s reported overdose before authorizing a replacement dose. The doctor has since accepted responsibility for his actions.
In light of this incident, there have been calls for stricter regulations regarding the use of unapproved peptides in Australia, mirroring ongoing concerns about such substances in the U.S. where some peptides are used in FDA-approved medications, while others circulate in a largely unregulated grey market.
The case highlights the need for increased scrutiny of peptide treatments and a better understanding of their potential risks, especially as regulatory bodies consider how to handle these controversial substances moving forward.
