Note: If you are an athlete competing under International Olympic Committee (IOC) or World Anti-Doping Agency (WADA) rules, it should be noted that the IOC and WADA have banned any substance that artificially enhances the uptake, transport, or delivery of oxygen. Because this ban might include Oxydrene (due to its ability to increase oxygen uptake at peak exercise levels), competitive athletes should check with their trainers and governing bodies before using Oxydrene in organized athletic competition.
