As eluded to before, each and every anabolic steroid carries an anabolic and androgenic nature, and as such, we can define this nature by its specific rating. The anabolic and androgenic rating of a particular steroid defines its nature in the anabolic and androgenic regard, but as discussed, what is more important is how these natures translate into action once in the body. Recall our example of Halotestin, a powerful steroid that carries a strong anabolic and androgenic rating, in-fact they are massive yet it displays very few androgenic traits. Then we have steroids like Anadrol that while it carries a modest androgenic rating and decent anabolic rating it translates into action of a higher nature regarding both.
For example, anabolic steroids such as Testosterone have a tendency to promote water retention through their ability to be aromatized into Estrogen via the aromatase enzyme. While such an effect might not be a concern for a strength athlete or a powerlifter (such an effect might even be beneficial or desired in such sports), this is not a desired effect for athletes involved in sports that involve speed and swiftness, such as sprinting. Instead, a sprinter, for example, would more likely opt for an anabolic steroid such as Stanozolol ( Winstrol ) or Oxandrolone ( Anavar ), which are two anabolic steroids unable to convert into Estrogen and therefore the issue of water retention, and therefore the issue of added weight that would slow the athlete down is avoided. Many athletes may also elect to ‘stack’ anabolic steroids in a given cycle (stacking refers to the practice of combining more than one anabolic steroid in a cycle). In the case of cycle stacks, an individual might be able to increase the synergy and synergistic effects between the anabolic steroids to create a highly anabolic environment or to create a stack that might assist the user in favoring certain particular athletic or physique goals. These are some of the major reasons as to why the development of different types of steroids has been done.
