4.8 from 11 reviewsAnavar is oxandrolone, an oral DHT derivative first approved to help patients regain weight after surgery, burns or long illness. It is one of the most studied oral anabolic steroids in clinical medicine.
Oxandrolone activates androgen receptors and is resistant to liver breakdown thanks to a chemical change at the 17-alpha position. It does not convert to estradiol, but it still lowers natural testosterone and strongly lowers HDL cholesterol.
From PubChem, the US National Library of Medicine’s chemistry database.

The original Oxandrin label used 2.5 to 20 mg a day, split into two to four doses, for two to four weeks, repeated only when needed. The United States withdrew the product in 2023.
Label and guideline amounts are shown for reference only. They are not a recommendation, and we never give cycle or performance amounts. Any use belongs under a doctor’s care, with bloodwork.

Raised liver enzymes are common; rare cases of liver tumours and peliosis hepatis are described with 17-alpha-alkylated steroids.
Oral steroids lower HDL more than most injectables.
Even at clinical amounts natural testosterone falls.
Voice deepening and other masculine changes can be permanent.
People under 18, anyone pregnant or breastfeeding, and anyone with liver disease, heart disease, uncontrolled blood pressure or a hormone-sensitive cancer, unless a doctor directs otherwise.
Anabolic steroids are listed in Schedule IV of the Controlled Drugs and Substances Act. Simple possession of a Schedule IV substance is not an offence under the Act; selling, importing or exporting one without authorisation is. Sports bodies that follow the World Anti-Doping Code ban them in and out of competition. This is general information, not legal advice.

No oral 17-alpha-alkylated steroid is liver-safe; oxandrolone is milder than some, but liver enzymes still rise.
Its half-life is about nine to ten hours.
