Steroids with Oxandrolone have very mild side effects making them useful for burning some fats before a competition. The testosterone undecanoate is the only form of oral testosterone. It is a synthetic steroid with an equal ratio of both anabolic and androgenic characteristics. At the correct dosses, this steroid achieves great results as it has low bioavailability. Other oral anabolic steroids include methandrosenolone commonly known as Dianabol, Halotestin, Primobolan that contain Methonolone acetate, mesterolone containing Proviron and the stanozolol containing Winstrol.
These types of steroids are generally made by non-licensed manufacturers and are not overseen by any regulatory board. Due to it becoming increasingly harder to obtain pharmaceutical grade steroids, most people opt for underground brands. The main problem with underground brands is no one knows what type of environment these steroids are produced in. They may or may not be produced in a sterile environment. There are however many big underground brands available that have hundreds of positive reviews, it is always best to stick with the big brands.
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.
