Health Warning Issued Over Illegal Peptides After Liver Injury Cases in Victoria
22 Jun 2026
Six cases of acute liver toxicity have been recorded in Victoria in 2026. All cases have been linked to an unapproved peptide product sold as Retatrutide.
Health authorities say the product was bought online, through social media ads, and via personal contacts. It was promoted for muscle growth, fat loss, recovery, and anti-ageing purposes.
Victoria’s Chief Health Officer, Dr Caroline McElnay, said early findings suggest possible contamination in the products may be contributing to the liver damage. She has advised doctors to check for peptide use in patients showing liver-related symptoms or abnormal test results.
The Therapeutic Goods Administration (TGA) has also confirmed reports of serious side effects linked to unapproved peptides, including liver injury, severe allergic reactions, and inflammation.
Professor Kidd said these products have not undergone proper clinical testing and may pose significant health risks. He urged Australians not to use unapproved peptides and to seek medical advice instead.
Authorities also noted a rise in imports, online promotion, and supply of these products, calling it a growing public health concern. Regulators have now made unapproved peptides a priority enforcement focus for 2026.
