Claim: Oxandrolone is in more than five medications, one of which is Testosterone.
Evidence: Oxandrolone, sold under the brand names Oxandrin and Anavar, among others, is an androgen and anabolic steroid (AAS) medication which is used to help promote weight gain in various situations, to help offset protein catabolism caused by long-term corticosteroid therapy, to support recovery from severe burns, to treat bone pain associated with osteoporosis, to aid in the development of girls with Turner syndrome, and for other indications. Like other AAS, oxandrolone is an agonist of the androgen receptor, similar to androgens such as testosterone and DHT. Oxandrolone is one of the few AAS that remain available for medical use in the United States. The others (as of November 2017) are testosterone, testosterone cypionate, testosterone enanthate, testosterone undecanoate, methyltestosterone, fluoxymesterone, and oxymetholone. Testosterone (T) is a medication and naturally occurring steroid hormone.
