Bodybuilders and power lifters, in particular, like Oxandrolone for three reasons. First, Oxandrolone causes a strong strength gain by stimulating the phosphocreatine synthesis in the muscle cell without depositing liquid (water) in the joints and the muscles. Power lifters and weightlifters who do not want to end up in a higher weight class take advantage of this since it allows them to get stronger without gaining body weight at the same time. The combination of Oxandrolone and 20 - 30 mg Halotestin daily has proven to be very effective since the muscles also look harder. Similarly good results can be achieved by a simultaneous intake of Oxandrolone and 120-140 mcg Clenbuterol per day. Although Oxandrolone itself does not cause a noticeable muscle growth it can clearly improve the muscle-developing effect of many steroids. Deca-Durabolin, Dianabol, and the various testosterone compounds, in particular, combine well with Oxandrolone to achieve a "mass buildup" because the strength gain caused by the intake of these highly tissue-developing and liquid-retaining substances results in an additional muscle mass. A stack of 200 mg Deca-Durabolin/week, 500 mg Testosterone Enanthate (e.g. Testoviron Depot 250)/week, and 25 mg Oxandrolone/day leads to a good gain in strength and mass in most athletes. Deca-Durabolin has a distinct anabolic effect and stimulates the synthesis of protein; Oxandrolone improves the strength by a higher phosphocreatine synthesis; and Testosterone Enanthate increases the aggressiveness for the workout and accelerates regeneration.

The second reason why Oxandrolone is so popular is that this compound does not aromatize in any dosage. As already mentioned, a certain part of the testosterone present in the body is converted into estrogen. This aromatization process, depending on the predisposition, can vary distinctly from one athlete to another. Oxandrolone is one of the few steroids, which cannot aromatize to estrogen. This characteristic has various advantages for the athlete. With Oxandrolone the muscle system does not get the typical watery appearance as with many steroids, thus making it very interesting during the preparation for a competition. In this phase it is especially important to keep the estrogen level as low as possible since estrogen programs the body to store water even if the diet is calorie-reduced. In combination with a diet, Oxandrolone helps to make the muscles hard and ripped. Although Oxandrolone itself does not break down fat, it plays an indirect role in this process because the substance often suppresses the athlete's appetite. Oxandrolone can also cause some bloating, which in several athletes, results in nausea and vomiting when the tablets are taken with meals. The package insert of the Italian Oxandrolone notes its effect on the activity of the gastrointestinal tract. Some athletes thus report continued diarrhea. Although these symptoms are not very pleasant they still help the athlete break down fat and become harder. Those who work out for a competition or are interested in gaining quality muscles should combine Oxandrolone with steroids such as Winstrol, Parabolan, Masteron, Primobolan, and Testosterone Propionate. A stack of 50 mg Winstrol every two days, 50 mg Testosterone Propionate every two days, and 25 mg Oxandrolone every day has proven effective. Another advantage of Oxandrolone's non-aromatization is that athletes who suffer from high blood pressure or develop gynecomastia of the thymus glands when taking stronger androgenic steroids will not have these side effects with this compound. The. Oxandrolone/Deca-Durabolin stack is a welcome alternative for this group of athletes or for athletes showing signs of poor health during mass buildup with testosterone, Dianabol, or Anadrol 50. Athletes over forty should predominantly use Oxandrolone.

The third reason which speaks well for an intake of Oxandrolone is that even in a very high dosage this compound does not influence the body's own testosterone production. To make this clear: Oxandrolone does not suppress the body's own hormone production. The reason is that it does not have a negative feedback mechanism on the hypothalamohypophysial testicular axis, meaning that during the intake of Oxandrolone, unlike during the intake of most anabolic steroids, the testes signal the hypothalamus not to reduce or to stop the release of GnRH (gonadotropin releasing hormone) and LHRH Luteinizing hormone releasing hormone). This special feature of Oxandrolone can be explained by the fact that the substance is not converted into estrogen Oxandrolone (Anavar), when given to normal men in high doses does not reduce the seminal volume or count, nor can it be converted (aromatized) into estrogen.
