To all trainers and equine veterinarians
NHA analysis of a locally sourced altrenogest-containing product has revealed trace levels of trendione and trenbolone as impurities within the product. This has been reported previously in international racing jurisdictions. Trendione and trenbolone are anabolic steroids which are forbidden substances and are not allowed to be present in any horse at any time under the NHA Rules of Racing. Significant penalties may apply for the person responsible and the horse involved, including a 365 day suspension from racing should these forbidden substances be detected in a specimen collected from a horse at any time.
