The Oxandrolone hormone does not carry any estrogenic related side effects. It does not aromatize and cannot lead to gynecomastia or water retention due to increases in estrogen levels. It further carries no progestin related activity, which again supports no estrogenic related side effects. Due to water retention being impossible with this steroid, this will decrease the risk of high blood pressure. Excess water retention can promote high blood pressure. Some steroids that do not aromatize can lead to high blood pressure, such as Trenbolone , but Anavar is rarely associated with this trait.
Anabolic steroids are synthetic derivatives of testosterone . Certain clinical effects and adverse reactions demonstrate the androgenic properties of this class of drugs. Complete dissociation of anabolic and androgenic effects has not been achieved. The actions of anabolic steroids are therefore similar to those of male sex hormones with the possibility of causing serious disturbances of growth and sexual development if given to young children. Anabolic steroids suppress the gonadotropic functions of the pituitary and may exert a direct effect upon the testes .
It has some mild side effects associated with it as well. Side effects occur when you take it for a very long period of time and in more quantity. Major drawback of Anavar is that it is too costly, although available in black market but one cannot be so sure of the authenticity of it bought from there. As it is DHT and due to this hair loss and acne can occur. But hair loss only in men who have got this hair loss disease genetically transmitted. There could be high blood pressure and high cholesterol levels but only for those who are not living a healthy life style and these diseases are not transmitted genetically to the users as well. Due to the non aromatizing nature of Anavar it has taken side effects of water retention and Gynecomastia out of the equation.
