Queensland trainers want the state's authorities to give them a clear guideline on the use of the drug altrenogest.
The synthetic progesterone compound is used to regulate the oestrus cycle in racing fillies and mares.
In June, Racing Victoria's Integrity Services Department issued a warning that products containing altrenogest may also test positive for the steroids trenbolone and/or trendione.
Trenbolone and trendione are permanently banned substances with the potential for prolonged detection times.
The warning was passed on to trainers in Queensland.
The secretary of the Queensland branch of the Australian Trainers Association, Cameron Partington, said NSW had introduced a local rule and Victoria was being proactive on the issue.
"Queensland hasn't indicated that their labs have even detected a trace of anabolic in fillies and mares," Partington said.
He said trainers would like an indication Queensland would look to introduce a local rule, similar to NSW, that would let trainers off the hook if small traces of anabolics were detected in swabs of fillies and mares treated with altrenogest.
The NSW rule allows for traces less than 1mcg/litre and trainers have also been advised not to use injectable products containing altrenogest.
