WADA is the World Anti Doping Agency. They are the body that pursued the Lance Armstrong case to conclusion.
As a serious sports person, it's your own responsibility to ensure you don't use anything on their prohibited list, so at the end of this post, you'll find a handy link where you can download your own copy of their 2013 list.
You'll find a full and detailed list of the types of doping which are prohibited, as well as a list of each of the banned substances - some may surprise you!
A few years ago, WADA actually banned canned oxygen, or to use the American term, supplemental oxygen. But since 2011, they have approved it's use. You'll find the reference to it on page 6, section M1, which talks about manipulation of blood and blood components.
Point 2 says that the following are prohibited:
Artificially enhancing the uptake, transport or delivery of oxygen, including,
but not limited to, perfluorochemicals, efaproxiral (RSR13) and modified
haemoglobin products (e.g. haemoglobin-based blood substitutes,
microencapsulated haemoglobin products), excluding supplemental oxygen.
booost is approved and acceptable for use in all sports, and unlike so many products, there are no downsides to using oxygen - no caffeine, no sugar, no "low" after using it.
