Steroid Tested

NOW® Sports products bearing the Steroid-Tested logo have been tested by our state of the art in-house laboratory. We have developed our own testing method using our high resolution, accurate mass LC-Orbitrap-MS instrument. More than just steroid testing, it focuses on banned substances found in the World Anti-Doping Agency (WADA) banned substance list including androgenic anabolic steroids, Selective Androgen Receptor Modulators (SARMs), selective serotonin reuptake inhibitor (SSRI), beta-agonists, estrogen inhibitors, and weight loss drugs. The complete list of tested substances is available upon request.
