As a supplement, TST 1700 has a potent combination of testosterone boosting natural ingredients that are supported by complementary ingredients for a good overall increase in athletic performance. It is nice that it does not have many redundant ingredients. All of its testosterone boosting ingredients play a slightly different role in increase overall testosterone levels, and it is one of the few boosters that combines these specific ingredients. Although a few of its ingredients have highly questionable efficacy, the product overall represents a good testosterone boosting formula that should have some additional workout enhancing effects.
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.
