Steroid Tested

NOW® Sports products bearing the Steroid-Tested logo have been tested to be under 500 ppb of steroids by our state of the art in-house laboratory. We have developed our own testing method using our LC-TOF-MS instrument. It focuses on testing for the following steroids: fluoxymesterone, stanazol, boldenone, nandrolone, methandienone, testosterone, methyl-testosterone, and androstenedione.
