Australian actor Richard Norton‘s death has been linked to unapproved peptide injections.

The martial arts legend’s sudden death was “triggered by” a peptide stack … according to a coroner in Melbourne, where he died.

Richard’s death is believed to be the first in Australia attributed to peptide usage.

As we reported … Richard died March 30, 2025, in Melbourne after suffering cardiac arrest, which was apparently triggered by the peptides.

Richard had a prescription for the anti-aging substance … but the coroner said he took more than the prescribed dose.

The coroner’s report says … “The injection caused an anaphylactic reaction which in turn led to cardiac arrest.”

Richard worked alongside Hollywood heavyweights … including Chuck Norris, Margot Robbie, Jackie Chan, Ben Affleck, Scarlett Johansson, Charlize Theron, Liam Neeson and more.

He is survived by his wife, actress Judy Green.
