Oxandrolone is a dihydrotestosterone (DHT) derived anabolic androgenic steroid. Specifically, Oxandrolone is the DHT hormone with the addition of an oxygen atom in place of the carbon-2 in the A-ring. This simple alternation dramatically increases the hormone’s anabolic power and prevents if from being metabolically broken down. The hormone is then altered again at the 17th carbon position through the addition of a methyl group. This allows Oxandrolone to be ingested orally without being destroyed by the liver and officially classifies it as a C17-alpha alkylated (C17-aa) anabolic steroid.
