Oxandrolone is a steroid that mild in anabolic nature, and was actually used as a treatment to promote growth in children. Oxandrolone is commonly referred to as Anavar, the brand name given by the drug manufacturer Searle. Being a derivative of dihydrotestosterone we have a steroid that is already 5-alpha reduced, and therefore possesses reduced androgenic activity.

As the steroid does not aromatised we have a steroid that is popular amongst those who are prone to oestrogen related side effects. There is no need for an anti-oestrogen such as Nolvadex whilst running oxandrolone on its own.

Oxandrolone is a popular choice for cutting cycles, being a non-aromatising steroid we have no worry of the build up of subcutaneous fluids that may cause a less defined look. Its mild anabolic nature make it a decent choice for slow solid gains in muscle, or for the preservation of muscle mass whilst on a calorie restricted diet. When stacked with other non-aromatising steroids such as Winstrol or Primobolan we can end up with more noticeable results, whilst not retaining any subcutaneous fluids. Adding a non-aromatising androgen will further promote a much more enhanced harder and defined look, such as with Trenbolone. Oxandrolone may be added to a bulking cycle to add its anabolic nature to the overall stack, with no added oestrogen side effects. However, its anabolic nature is mild, and oxandrolone can often suppress the appetite which is obviously not what we want whilst trying add muscle mass.

Studies have shown low doses resulting in little impact on natural Testosterone production. This is likely because of the moderate dosages used, and the fact no oestrogen is produced which often acts as a major suppression of natural testosterone production via negative feedback with other steroid therapies. As with any steroid use however, suppression of natural production is possible, especially as we use higher doses, therefore post cycle therapy is a must.

Being a 17alpha alkylated oral steroid we would expect oxandrolone to be toxic to the liver, thus dosage and duration of use have to be planned to not cause damage to the liver. Reports however has shown that oxandrolone is a lot less in hepatotoxicity nature compared to other 17alpha alkylated orals. We could therefore conclude that higher dosages and longer duration of use is possible with this compound compared to many other orals. This is true, however no one should forget that the risk still exists and care should always be taken to not use this drug excessively in dose or duration. It should also be taken in account if stacked with other orals or compounds that may also have an impact on strained placed on the liver.
