Without a prescription, anabolic steroids are illegal in Australia. But that doesn’t stop “gym bros” and various online providers selling these drugs to people who want to grow bigger muscles and improve their athletic performance.

These illicit products are unregulated and don’t pass official quality checks.

A new study tested several products from Australia’s underground steroid market and found the vast majority were either mislabelled or contained the wrong drug. Alarmingly, all had some level of heavy metal contamination.

People aren't going to stop using steroids – what we need is better testing, surveillance and regulation to prevent harm.

Until next week,
