Health regulators in Western Australia issue an urgent warning about the unapproved peptide retatrutide, following reports of serious liver injury in multiple people. PerthNow and The West Australian report that a state health watchdog is alerting the public after six individuals experienced liver damage. The regulator’s message focuses on the risks linked to using an unapproved product and urges caution around retatrutide sourced outside approved medical pathways. The outlets describe the warning as “urgent,” indicating the health authority is treating the reported adverse effects seriously and wants people to avoid or stop using the substance unless it is provided through regulated channels. While both reports align on the existence of six cases of serious liver injury and the regulator’s decision to issue a warning, they do not provide additional clinical details or the exact circumstances of how the product was obtained in the information provided. The regulator’s action reflects concerns about safety and the potential consequences of using substances that have not been approved for the relevant indications.
