Deca-Durabolin is more widely known as “Deca” and is the brand name for the anabolic steroid and parent hormone Nandrolone. Deca-Durabolin is specifically the trade name for the anabolic steroid Nandrolone Deconoate – this is the longer ester variant of the Nandrolone hormone. Deca-Durabolin is one of the most popular injectable anabolic steroids used today. We’d actually put it in the top three most used anabolic steroids of all time. Just behind the oral steroid Dianabol (Methandrostenolone) and primarily cutting anabolic Winstrol (Stanozolol).

The medical community first saw Nandrolone Deconoate in 1960[1], making it one of the first anabolic steroids ever produced after Testosterone variations. It was produced by pharmaceutical giant Organon and in 1962 was released into the prescription drug market. To this day, many believe Deca-Durabolin was the first Nandrolone type steroid produced, but this is false. The faster acting Nandrolone Phenylpropionate, known widely as NPP, was seen in 1957 but because of its quick acting ester and more frequent administration was not seen as effective. Nandrolone Phenylpropionate needs to be injected every day or every other day for effective and stable blood plasma concentrations, however this short half-life made it unpopular among medical experts. Therefore, Nandrolone was attached to the longer ester Deconoate and Deca-Durabolin was born. With the Deconoate ester now attached, injections were now every 15 days as opposed to a lot more regularly.
