NSW Health Warns of Surge in Hospital Presentations Linked to Unapproved Peptides

NSW Health has issued a public warning after surveillance data revealed a sharp increase in emergency department presentations linked to the use of unapproved peptide products across New South Wales between July 2025 and September 2026.

According to a report released by the health department, 1,180 presentations associated with peptide use were recorded during the 15-month period. Presentations rose from five in July 2025 to more than 217 in September 2026, marking a significant rise for incidents that were previously considered very rare.

NSW Health noted that unapproved peptides are frequently marketed on social media for "wellness" purposes, such as weight loss, injury repair, and anti-ageing. Substances commonly named in these products include BPC-157, GHK-Cu, TB-500, retatrutide, and CJC-1295. The department stated that none of these peptides are currently approved for any purpose in Australia.

Health authorities warned that unapproved products sourced from social media, online retailers, overseas suppliers, or informal sellers pose serious risks. They may contain unknown or harmful substances, incorrect dosages, or ingredients different from those listed on the packaging, regardless of whether the items appear professionally packaged or claim to be purity-tested.

Reports of serious illnesses associated with peptide use received from clinicians have included kidney damage and liver injury. When serious illness is identified, NSW Health collaborates with the Therapeutic Goods Administration (TGA) and law enforcement agencies to investigate product sources.

NSW Minister for Health Ryan Park highlighted the strain on medical services, stating, "We know that using these unapproved substances can come with real health risks, but it's particularly alarming to see the growing pressure they're placing on our health system." Park urged individuals to consult their general practitioners for evidence-based advice.

NSW Health Chief Health Officer Dr Kerry Chant cautioned consumers against relying on visual marketing, noting that professional websites, labels, purity claims, reviews, or influencer endorsements do not guarantee product safety or accurately reflect the contents inside.

NSW Health advised individuals using peptide products to inform their treating healthcare professionals, especially prior to surgery or receiving other medical treatments, due to the risk of complications when combined with other medicines.
