Oxandrolone appears to offer less hepatic stress than other c-17 alpha alkylated steroids. The manufacturer identifies oxandrolone as a steroid that is not extensively metabolized by the liver like other 17-alpha alkylated orals, which may be a factor in its reduced hepatotoxicity. This is evidenced by the fact that more than a third of the compound is still intact when excreted in the urine. 405 Another study comparing the effects of oxandrolone to other alkylated agents including methyltestosterone, norethandrolone, fluoxymesterone, and methandriol demonstrated that oxandrolone causes the lowest sulfobromophthalein (BSP; a marker of liver stress) retention of the agents tested. 406 20 mg of oxandrolone produced 72% less BSP retention than an equal dosage of fluoxymesterone,which is a considerable difference being that they are both 17-alpha alkylated.
This drug was first produced in 1964 by a company called Searle. It was designed to be a safe and mind anabolic steroid and in low doses was well tolerated by women and children. Oxandrolone is a Class I anabolic, mildly androgenic steroid, which makes it safe to use in many cases. This drug has been used for anything from, burn victims to treatment of osteoporosis as it provides calcium to the body which will aid in bone regeneration. However in 1989 this drug was discontinued by Searle Laboratories partly due to the illegal use among bodybuilders. Around 6 years later Bio-Technology General Corp negotiated a deal with Searle where they would continue to manufacture the drug Anavar and supply it to BTG. This is when a press release went out stating its effects on involuntary weight loss and focused itself on HIV/AID’s wasting indications which were approved by the FDA where they were able to dictate the price by it being granted Orphan Drug status by the Food and Drug Administration.
