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 men-tioned, 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.
