A simple and sensitive method for the determination of methandienone and its metabolite in human urine by HPLC, using methyotestosterone as internal standard, was developed. The urine sample was first purified by solid phase extraction method, and then determined by HPLC with detective wavelength at 254 nm. The mobile phase was methanol-water (100: 40 V/V). It showed a good linearity between the range of 0.05~1.0 μg/ml with the correlation coefficient of 0.9993. The detective limit was 5 ng, and the sensitivity was 25 ng/ml. The precisions of both within-day and day-to-day were less than 5%. This method was found to be much simpler and more inexpensive than that of GC-MS, and it could serve as an alternative method for the doping control in athletes training.
