Health officials in Victoria are warning the public about the dangers of illegal 'backyard' peptides after a surge in emergency department visits. Patients have reported severe side effects including amputations, heart attacks, and days of vomiting, according to a report published on May 17, 2026.
The peptides, often sold online or through unregulated channels, are being used for weight loss, muscle building, and anti-aging purposes. However, authorities have not confirmed the specific types of peptides involved or the exact number of cases.
Victoria's Department of Health advises that these substances are not approved for human use and can cause life-threatening complications. The public is urged to avoid purchasing or using any unregulated peptide products.
