Dienedione, also known as estra-4,9-diene-3,17-dione, is a synthetic, orally active anabolic-androgenic steroid (AAS) of the 19-nortestosterone group that was never introduced for medical use. It is thought to be a prohormone of dienolone.^[1] The drug became a controlled substance in the US on January 4, 2010,^[2] and is classified as a Schedule III anabolic steroid under the United States Controlled Substances Act. Previous to this, it was sold as a bodybuilding supplement within the United States, and often mistakenly marketed as a prohormone for trenbolone, a veterinary steroid. Prior to its scheduling, it was part of a number of supplements that were seized during FDA enforcement of Bodybuilding.com for selling unapproved new drugs.^[3] The actual active metabolite, dienolone, is almost identical to trenbolone structurally, but lacks the C11 double bond.
