Boldenone Undecylenate is a testosterone derived anabolic androgenic steroid that is best known by the trade name Equipoise given to it by Squibb in the 1970’s. While Equipoise is officially classified as a veterinarian grade anabolic steroid, the first batches of Boldenone were introduced on the human grade pharmaceutical market by Ciba in the early 1950’s under the brand name Parenabol. Human grade Boldenone would see some success in human medicine through the 1960’s and 70’s but would ultimately be discontinued by the end of the decade. Since that time, the steroid has only been available through veterinarian medicine and underground labs with the Equipoise name dominating the market. Fort Dodge Animal Health now owns the Equipoise name.
