Since the days of Arnold Schwarzenegger drug abuse has been rampant among body builders. They always are looking for the best steroid to help their muscles recovery more quickly so they can work out longer and harder. In Australia, drug abuse among those serious gym rats is becoming concerning.
They are a growing subculture known as "shredders" - Perth men who spend hours in the gym in pursuit of the "perfect" male body. The young, often tattooed, men are usually seen with arms and chest bulging through super-tight muscle shirts, if they are wearing a shirt at all.
This month they are expected to descend on the Stereosonic music festival at Claremont Showgrounds, an event fast becoming the shredders' Olympic Games.
More than 20,000 Facebook users have joined the group.
But the shredders' pursuit of "perfection", it seems, is not always legitimate. A growing number, at least anecdotally, use steroids, a trend that worries drug experts.
The Australian Crime Commission's most recent drug report reveals steroid detection at Australian borders increased 74 per cent in 2009-10, the most for a decade.
In June, a Perth man was charged in WA after trying to sell about 2.2 liters of steroids through online classified site Gumtree.
The dangers of drug use were laid bare when Sydney bodybuilder and internet celebrity Aziz Shavershian died in Thailand in August.
Better known as "Zyzz", the self-proclaimed "son of Zeus and brother of Hercules" created his own bodybuilding brand and inspired 120,000 Facebook to "get aesthetic".
One month before Zyzz's death, his older brother was charged with possession of anabolic steroids.
Zyzz's family said he died from a previously undiagnosed congenital heart condition, but others suggested drugs were involved.
He posted "wanna ride a bicycle tonight" on the shredders' Stereosonic page and in shredder speak, this means to "cycle" on steroids.
Anabolic steroids are illegal drugs too. As such they can be abused like any other drug.
