Popular because of its versatile way of acting as an anabolic steroid and compared to Winstrol's less negative effect, oxandrolone brings a good package of benefits to athletes and bodybuilders. You can find out all about this steroid here:
The anabolic steroid oxandrolone was officially marketed in 1964 under the brand name Anavar. Anavar was designed to deliver a steroid that has an extremely low androgenic effect. Compared to testosterone, the active substance oxandrolone has only about a quarter of the androgenic effect, which is in part due to the fact that Anavar is a derivative of dihydrotestosterone, which cannot be converted into androgenic dihydrotestosterone by the 5-reductase enzyme. The androgenic effect of Anavar is so mild that oxandrolone could be used even in children to promote growth and in women to treat osteoporosis. In fact, oxandrolone is the only anabolic steroid that does not have a negative impact on the longitudinal growth of adolescents. At the end of the eighties, Anavar was withdrawn from the market due to the backward sales figures in America and other countries until a few years ago the potential of the active substance oxandrolone in the treatment of AIDS was recognized, which led to the production of oxandrolone being resumed at least in America.
Oxandrolone is a dihydrotestosterone derivative which has been made orally available by means of 17-alpha alkylation. Surprisingly, oxandrolone has, despite its 17-alpha alkylation, an amazingly low potential for liver damage. Various studies comparing liver burden of various 17-alpha-alkylated steroids, such as methyltestosterone, fluoxymesterone (halotestine), and methandriol, to oxandrolone-induced liver burden showed that oxandrolone caused the least amount of liver burden of all investigated oral anabolic androgenic steroids. For example, the liver burden of 20 mg of Anavar was about 70 percent less than the liver burden caused by the same amount of halotestin. Some manufacturers write in the instruction leaflet that a multi-month application of oxandrolone affects the liver function only insignificantly negative.
The anabolic androgenic steroid Anavar is used during the competition preparation and the diet, since oxandrolone brings about a good increase in strength and gives the muscles a much tougher appearance, which is due among other things to the non-existent conversion to estrogen. In practice, dosages in the range of 15 to 25 mg oxandrolone are observed for this area of application, which are often combined with other non-aromatizing anabolic androgenic steroids such as Primobolan (methenolone), Winstrol (stanozolol), Halotestin and / or trenbolone. Since the half-life of oxandrolone is in the range of 8 to 12 hours, it is taken by most athletes only twice a day. Particularly interesting for the definition phase is the fact that some studies have shown that oxandrolone can reduce the body fat percentage - in one study even without accompanying sports activities and a dosage of only 20 mg oxandrolone per day!
Oxandrolone is only conditionally suitable for mass build-up because the intake does not lead to significant mass growth as is typical for so-called mass esteroids (testosterone, dianabol, anapolon). However, the muscular mass built up with the help of oxandrolone is of high quality and can be kept almost completely after discontinuation. However, dosages in the range of 20 - 100 mg are necessary for the muscle build-up in oxandrolone.
Owing to its structure, oxandrolone cannot be converted into estrogen by the aromatase enzyme, which is why estrogen-induced side effects such as water retention, increased blood pressure and gynecomastia are not a problem when taking oxandrolone. Since the anabolic androgenic steroid oxandrolone has only a very low androgenic effect, there are little androgen-induced side effects when taken, which is why oxandrolone is also used by women who are afraid of the "masculinities" associated with other anabolic androgenic steroids. The dosage observed in practice in women is in the range of 5 to 25 mg oxandrolone per day. All in all, oxandrolone is a very low-side-effect anabolic androgenic steroid, which in practice has very few side effects, even at high doses of up to 80 mg per day.
Owing to the fact that oxandrolone has only a very low androgenic effect on the one hand and does not convert to estrogen on the other, it suppresses the testosterone production significantly less than other anabolic androgenic steroids. This is due to the fact that a negative feedback on the body's production of testosterone is caused by an excess amount of androgenic active substances or an increased estrogen level. Both are not present at moderate doses of oxandrolone. At higher doses of oxandrolone, however, the androgenic components become more active, which also leads to a greater suppression of the testosterone production.
