Trainer Gerard Butler has been charged by the British Horseracing Authority (BHA) after nine of his racehorses tested positive for banned anabolic steroids reports the BBC.
Butler has admitted giving horses the Sungate product for injured joints but said that he had been told the substance didn't break rules.
The nine horses have been suspended and Butler could face a penalty ranging from a fine to a 10-year ban if found guilty.
Trainer Mahmood Al Zarooni was given an eight-year ban in April for being found guilty of a similar offence.
A Touch Of Fashion, Flemish School, Azrag, La Belle Epoque, Rainbow Beauty, Zain Eagle, Zain Queen, Zain Spirit and Prince Alzain are the nine horses that tested positive.
But Butler has said that more than 100 horses in Newmarket would have been given the same drug, Stargate, which contains stanozolol.
The nice horse have won a total of nine races between them winning combined prize money of £22,594. Azrag has won four races and Prince Alzain has won three.
Butler said the treatment came recommended by vets, unlike the Al Zarooni case, and believes Sungate has been 'misunderstood by many others.'
Eleven of Al Zarooni's horses were found guilty of drug testing with four testing positive for stanozolol and seven were found to have ethylestrenol in their system.
