Police raid sports medicine clinic in $4m steroid bust

Detectives have seized 17 luxury cars and $700,000 in cash as part of their investigation into a Melbourne sports medicine clinic owner allegedly selling steroids.

Officers on Thursday raided Melbourne Sports Medicine and Anti-Aging Clinic at Moonee Ponds, in Melbourne's northwest, where they allegedly found a large amount of illegal prescription medication including steroids and human growth hormones.

The raid followed a five-month investigation and detectives arrested 55-year-old Robin James Taylor - the alleged business owner - at a factory at Somerton in Melbourne's north a short time later.

Police searched the factory and seized about $700,000 in cash from a safe, along with 17 luxury cars including two Lamborghinis, a Porsche, a Corvette and a Mercedes-AMG.

They also seized six Holden Toranas, including a VK SS Peter Brock valued at $1 million.

Officers alleged the cars, which had a combined value of about $3 million, were the proceeds of Taylor's business dealings.

They charged the 55-year-old, from Yarrambat in Melbourne's northeast, with several offences including trafficking a commercial quantity of prescription drugs, trafficking a commercial quantity of steroidal agents and trafficking testosterone.

He fronted Melbourne Magistrates Court on Friday where he was denied bail after his barrister failed to prove he had exceptional circumstances.

Prosecutors alleged Taylor was selling drugs, including steroids, without medical qualifications at the premises, and using a blank prescription book already signed by a NSW-based doctor to give customers drugs.

Taylor is next due before court on June 21.
