Eighteen-year-old Mark scrolls Instagram late at night, watching videos of fitness influencers showing off muscle gains and lifting the equivalent of a baby elephant off the gym floor. Spurred on by hashtags and usernames indicating these feats involve steroids, soon Mark is online, ordering his first “steroid cycle”. No script, no warnings, just vials in the mail and the promise of “gains”.
A few weeks later, he’s posting progress shots and getting tagged as #MegaMark. He’s pleased. But what if I told you Mark was unknowingly injecting toxic chemicals? In our new research we tested products sold in Australia’s underground steroid market and found many were mislabelled or missing the expected steroid entirely.
Even more concerning, several contained heavy metals such as lead, arsenic and cadmium. These substances are known to cause cancer, heart disease and organ failure.
Anabolic steroids are synthetic drugs designed to mimic the effects of testosterone. Medical professionals sometimes prescribe them for specific health conditions (for example, hypogonadism, where the body isn’t making enough sex hormones). But they are more commonly taken by people looking to increase muscle size, improve athletic performance, or elevate feelings of wellbeing.
In Australia, it’s illegal to possess steroids without a prescription. This offence can attract large fines and prison terms (up to 25 years in Queensland).
Despite this, they’re widely available online and from your local “gym bro”. So it’s not surprising we’re seeing escalating use, particularly among young men and women.
People usually take steroids as pills and capsules or injectable oil- or water-based products. But while many people assume these products are safe if used correctly, they’re made outside regulated settings, with no official quality checks.
For this new study, we analysed 28 steroid products acquired from people all over Australia which they’d purchased either online or from peers in the gym. These included 16 injectable oils, ten varieties of oral tablets, and two “raw” powders.
An independent forensic lab tested the samples for active ingredients, contaminants and heavy metals. We then compared the results against what people thought they were taking.
More than half of the samples were mislabelled or contained the wrong drug. For example, one product labelled as testosterone enanthate (200mg/mL) contained 159mg/mL of trenbolone (a potent type of steroid) and no detectable testosterone. Oxandrolone (also known as “Anavar”, another type of steroid) tablets were sold claiming a strength of 10mg but actually contained 6.8mg, showing a disparity in purity.
Just four products matched their expected compound and purity within a 5% margin.
But the biggest concern was that all steroids we analysed were contaminated with some level of heavy metals, including lead, arsenic and cadmium.
While all of the concentrations we detected were within daily exposure limits regarded as safe by health authorities, more frequent and heavier use of these drugs would quickly see people who use steroids exceed safe thresholds. And we know this happens. (The Conversation)
