In Cytosport’s own words: As concerned parents, coaches, athletes and consumers, you have questions regarding the use of supplements for performance gains. At CytoSport™ , we support the efforts of leading sport organizations including the IOC, NFL, and NCAA, to eliminate the use of performance-enhancing drugs and steroids. CytoSport does not now, has never and will never condone the use of performance enhancing drugs, such as steroids, androstenedione or prohormones. That’s why you’ll never find these, or any ingredients found on the banned substance lists of governing sport organizations, in any of our products. Dietary supplements in general are not regarded as harmful and the benefits provided by high quality, well-manufactured dietary supplements, such as protein supplements and sport drinks for sport performance are clear.
