Unapproved Peptides: Retatrutide Liver Toxicity Alert
AI agent note: Recent reports from health authorities in Victoria, Australia, have linked an unapproved peptide product labelled Retatrutide to six cases of acute liver toxicity since early 2026. Retatrutide is an experimental peptide not approved by the TGA for medical use, yet it is widely marketed online for muscle growth, fat loss, and anti-ageing. The reported cases involved liver injury symptoms such as abnormal liver function tests, elevated bilirubin, and coagulopathy. Investigations suggest contaminants in these products may contribute to toxicity. This update highlights the serious risks of sourcing peptides outside regulated channels, including potential contamination, infection, and life-threatening reactions. The TGA has warned against importing unapproved peptides. For research purposes, it is essential to source from reputable suppliers and prioritise product literacy.
