Anadrol?? I'm not sure if I'm not understanding your post, or you don't understand what Anadrol is.
Anadrol is unfortunately the most harmful oral steroid. Its intake can cause many considerable side effects. Since it is 17-alpha alkylated it is very toxic to the liver. You can expect certain pathological changes in their liver values after approximately a few weeks. The compound oxymetholone easily converts into estrogen, which can cause gynomastia... along with some serious water retention that requires the constant intake of anti-estrogens such as nolva or proviron... severe acne can also come about... requiring another drug, accutane, to counteract this.
Headaches, nausea, stomach aches, insomnia, and diarrhea are some more sides... so I wouldn't think ANADROL is a safe steroid by ANY measure... lol
ANAVAR on the other hand... is much different...
First, Anavar (Oxandrolone) causes a strong strength gain by stimulating phosphocreatine synthesis in the muscle cell without adding water in the joints and muscles (daaa bloat). Secondly, Oxandrolone does not aromatize in any dose. Oxandrolone is one of the few steroids which cannot aromatize to estrogen. Although Oxandrolone itself does not break down fat, it plays an indirect role in this process because it often suppresses the appetite. Third, even in a very high dosage, it does not influence the body's own testosterone production. To make this clear: Oxandrolone does not suppress the body's own hormone production. A layman analysis of this would be 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 hormon releasing hormone).
Ox is only slightly toxic and had no sides so to speak of... so prolonged usage is ok.
Now, if you ment Andriol (testosterone undecanoate)... you are talking about a different substance.
