Australian actor Richard Norton’s fatal reaction to unapproved peptides sparks TGA review
Consensus Summary
The coroner’s findings and the TGA’s ongoing assessment suggest further regulatory action may be forthcoming, though no immediate changes have been announced. Norton’s case has drawn attention to the risks of unapproved peptides, particularly those promoted through social media or overseas suppliers, which may contain unknown or harmful substances. The Medical Board’s decision to impose only a caution on Dr. Muchnicki indicates a reluctance to penalize practitioners in the absence of clear evidence of negligence, though the coroner’s report underscores the need for better oversight. As NSW Health continues to warn the public about the dangers of these products, Norton’s death serves as a stark reminder of the potential consequences of using unregulated therapies.

Key details reported by multiple sources:
- Richard Norton, a 75-year-old Melbourne-based actor, stuntman, and martial artist, died on March 30, 2025, after suffering a cardiac arrest linked to unapproved peptides CJC1295 and Ipamorelin.
- Norton’s death is believed to be the first known fatality in Australia caused by unapproved peptide use.
- Coroner David Ryan released findings on October 28, 2026, recommending the Therapeutic Goods Administration (TGA) review the safety and therapeutic benefits of peptides like CJC1295 and Ipamorelin.
- Norton was prescribed CJC1295 and Ipamorelin by Dr. Jerzy Muchnicki on March 19, 2025, and later reported taking double the prescribed dose.
- The Medical Board of Australia found Dr. Muchnicki’s clinical notes were ‘sparse, inadequate, and perfunctory’ but did not warrant regulatory action beyond a caution and training.
- Norton had been injecting peptides twice a day for muscle growth and healing before his death.
- The TGA has reported six other instances of anaphylaxis or hypersensitivity linked to CJC1295, Ipamorelin, BPC157, Thymosin B4, and TB-500, including three cases of anaphylaxis from CJC1295 and Ipamorelin alone.
- NSW Health recorded 1180 emergency department presentations linked to peptide use between July 1, 2025, and September 30, 2026.
- Norton’s death occurred at the Alfred Hospital in Melbourne.
Points of Difference
Details reported by only one source:
- Norton’s wife told police he had been experiencing allergic reactions since his first injection.
- Norton was in possession of additional unapproved peptides, including BPC157, Thymosin B4, and TB-500.
- The coroner recommended the TGA consider stricter restrictions on unapproved peptides, including potential reclassification.
- Norton had been prescribed peptides by another practitioner before seeking treatment from Dr. Muchnicki.
- Norton worked as a fight choreographer and stuntman, collaborating with stars like Chuck Norris and serving as a bodyguard for David Bowie.
- The coroner’s report noted Norton had asthma, osteoarthritis, and previous shoulder surgeries.
- Dr. Muchnicki acknowledged his notes were ‘sparse, inadequate, and perfunctory’ and accepted accountability for his actions.
- The coroner suggested shifting peptides from Schedule 4 to Schedule 10 (clinical trials only).
- The coroner’s report stated Norton had been previously prescribed peptides by another practitioner for fatigue, shoulder pain, and muscle loss.
- The Medical Board of Australia’s decision in July this year found Dr. Muchnicki’s practice was ‘unsatisfactory’ but imposed no regulatory action beyond a caution.
Where the reporting differs
Details that conflict, or appear in only some outlets:
- The Guardian and ABC state Norton’s death occurred in March 2025, while 7NEWS specifies ‘March last year’ (2024) in one instance, though all agree the fatal event was March 30, 2025.
- 7NEWS reports Norton had been injecting peptides twice a day, but the Guardian and ABC do not specify frequency beyond his dose escalation.
- The Guardian and ABC mention Norton’s prior peptide use for fatigue and shoulder pain, while 7NEWS only notes his wife’s statement about reactions post-first injection.
