Sodium polydihydroxyphenylene thiosulfonate (гипоксен, Hypoxen) is under laboratory studies in Russia as a potential regulator of cell metabolism.[1] It is purported to affect mitochondrial function,[2] though this has not been proven in any high-quality, peer-reviewed publications.[citation needed]
It is registered in Russia as an antihypoxic agent, but has not been subjected to any clinical trials meeting internationally accepted standards, and has no regulatory approval as a prescription drug outside Russia and some former Soviet states. Although called an "oxygen booster" in public media to imply its potential to "increase endurance and reduce fatigue",[3][4] there is no scientific evidence it has this property, and it is not used in conventional cardiology as a therapy for treating heart disease.[5]
Hypoxen is sold online without a prescription, mainly from Russian websites, and does not appear to be sold in health stores in the United States.[5] Hypoxen is not listed on the prohibited substance list of the World Anti-Doping Agency.[5] In 2017, the United States Anti-Doping Agency applied to have hypoxen banned from athletic competitions, but the ban was not implemented.[3]
It has been identified in tests on athletes in competition, such as Kamila Valieva, a Russian figure-skater competing at the 2022 Winter Olympics, but is not itself banned in international competitions, as of 2022.[4][6]
It is claimed to be a polymeric mixture containing between 2 and 6 repeat units of 2,4-dihydroxyphenylene with a thiosulphonate group joined at the end.[7][8]
