Ethylestrenol and stanozolol are anabolic steroids which can be used to increase muscle mass and enhance performance. These drugs have been linked to instances of doping in race horses.
This application note describes a Supported Liquid Extraction (SLE) protocol for the extraction of ethylestrenol and stanozolol from horse urine prior to LC-MS/MS analysis.
The method achieves high reproducible analyte recoveries from both gelding and filly urine. Protocols for 48-well, 96-well plate and column formats are described.
