It is often assumed the side-effects of Anavar do not include testosterone suppression; this simply isn’t true. What is true is the Oxandrolone hormone has a very mild effect on your HPTA; it is mild, but it will affect it to a degree. Luteinizing Hormone (LH) and Sex Hormone Binding Globulin (SHBG) will both be suppressed, but Follicle Stimulating Hormone (FSH) will not. This is all important to note for a few reasons; with low to moderate doses, you may be able to supplement with Anavar and only Anavar without the need of exogenous testosterone supplementation; however, there are exceptions. For true performance doses, especially if other anabolic steroids are involved men will need at least enough exogenous testosterone to meet your body’s needs; failure to do so will result in an extremely unhealthy low testosterone condition.
Scientists have attempted to test the association between anabolic steroids and aggression by administering high steroid doses or placebo for days or weeks to human volunteers and then asking the people to report on their behavioral symptoms. To date, four such studies have been conducted. In three, high steroid doses did produce greater feelings of irritability and aggression than did placebo, although the effects appear to be highly variable across individuals. In one study, the drugs did not have that effect. One possible explanation, according to the researchers, is that some but not all anabolic steroids increase irritability and aggression. Recent animal studies show an increase in aggression after steroid administration.
