The California Horse Racing Board will enact severe penalties for excessive use of four anabolic steroids beginning with races run on Sept. 4, the board announced on Thursday.
The four anabolic steroids - boldenone, nandrolone, stanozolol and testosterone - the only steroids allowed to appear in postrace tests, will be allowed to appear at minute levels. The four steroids have been reclassified as Class 3 violations, from Class 4. Under the new rules, excessive levels of those steroids will result in the loss of a purse and a possible fine and/or suspension for a trainer.
