Description: Fluoxymesterone, a synthetic androgenic anabolic steroid hormone, is a halogenated derivative of 17-α-methyltestosterone. It produces nitrogen, K and phosphorus retention; increases protein anabolism; and decreases urinary Ca concentrations, and causes recalcification of osseous metastases and regression of soft tissue lesions.
