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.
For this reason, many men choose to supplement their Anavar with exogenous testosterone. This helps to keep testosterone levels in the normal range during their cycles, and it helps them avoid any Anavar side effects that may be associated with low testosterone levels, including things like testicular atrophy. It’s also important to follow a post-cycle therapy regimen carefully so you can help your body start producing its own testosterone after your cycle ends. The table below shows the amount of testosterone you should use based on its type.
