Deca Durabolin is an extremely popular anabolic steroid comprised of the steroidal hormone Nandrolone and is attached to the large Decanoate ester. The Nandrolone hormone first appeared in 1960 and developed for commercial use in 1962 by Organon under the trade name Deca Durabolin. Since that time numerous Nandrolone Decanoate versions have hit the market, but Deca Durabolin remains the most recognized. This was not the first Nandrolone compound ever created, that would belong to Organon’s Durabolin, which is specifically Nandrolone Phenylpropionate. The Phenylpropionate version is much faster acting with a less active duration, and while Phenylpropionate forms are popular, Deca Durabolin has largely dominated the Nandrolone marketplace. Deca Durabolin is one of the most commonly used anabolic steroids among performance enhancing athletes. It is well known for being a tremendously beneficial off-season mass steroid, but it’s also a favorite in many athletic circles for its therapeutic benefits. Due to its tremendous therapeutic benefits, the Nandrolone hormone is one of the most beneficial anabolic steroids in medical practice. However, due to years of anabolic steroid controversy such use has been quite limited in the U.S. for many years. Outside the U.S. Deca Durabolin remains a bit more popular in therapeutic treatment plans that can cover a host of areas.
