Almost all anabolic androgenic steroids can be used for both cutting and bulking purpose and all can have a place in most any type of cycle. The prime example would be of testosterone, the foundation of most all cycles and the best of both worlds. Testosterone can be used to aid in increasing both mass and strength. However, it can also be used to aid in preserving mass and strength while leaning out and it can serve both purposes in a primary way. While most steroids serve a multitude of purposes, most have a primary purpose; testosterone however can in a general sense be said to serve two primary purposes. Testosterone, however, is not the only steroid that can equally serve both purposes. Trenbolone is another steroid that fills this category, too.
