Like most anabolic steroids in use today, Equipoise® was originally developed as a veterinary steroid, primarily for horses. Its purpose, like all veterinary steroids, was to bulk up the animals with additional muscle mass and definition. The results gained with equipoise naturally created an interest in the sports and bodybuilding community.
Equipoise is compared by many to Dianabol, primarily because of the great chemical similarity between the two. However, their usage and effects are actually quite different. Equipoise is an injectable anabolic, while Dianabol is ingestible, due to its 17 alpha alkylated (17aa) alteration, which is what allows it to be assimilated through oral application. There are other important differences, as well.
