Oxandrolone, also known as oxandrin, is a drug first synthesized, under the trademark Anavar, and introduced into the United States in 1964. It is a synthetic anabolic steroid derivative of dihydrotestosterone with an oxygen atom replacing the 2 carbon and methylation in the 17 position.
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.
