Nandrolone is one of the most popular anabolic steroids to ever be created and has been a staple among performance enhancing athletes of all types since its inception. It is also one of the few anabolic steroids that has remained prominent in medical circles and is highly valued in many therapeutic fields.
Nandrolone was first developed in 1960 and made available worldwide in 1962 by Organon in the form of Nandrolone Phenylpropionate under the trade name Durabolin. However, it would be the trade name Deca Durabolin that would gain a hold on the Nandrolone drug. Since that time numerous versions of Nandrolone have hit the shelves, but Deca Durabolin has remained the most well known; in fact, it’s not uncommon for all Nandrolone versions to be referred to as Deca even if they aren’t.
The Nandrolone hormone can be attached to any ester but is most commonly found attached to the Decanoate and Phenylpropionate ester, and in some cases the Cypionate ester. Nandrolone is well known for being one of the best off-season bulking agents for steroid users. It is also a favorite among athletes for its healing and recovery benefits. Because of its tremendous therapeutic benefits Nandrolone is used in many areas of medicine. However, due to anabolic steroid controversy its use has waned somewhat in the U.S. but still remains high in the rest of the world.
Nandrolone (all forms) is a 19-nortestosterone (19-nor) anabolic androgenic steroid. The 19-nor distinction notes a structural change to the testosterone hormone, specifically the testosterone hormone lacking the carbon atom at the 19th position. It is this slight alteration that gives us Nandrolone; Testosterone, remove the 19th carbon and a new steroid is born.
 
Nandrolone is carries an anabolic rating that is slightly greater than testosterone, but possess a much lower androgenic rating. Its androgenic rating is a mere 37 with testosterone’s rating being 100. The decreased androgenic rating is due to Nandrolone’s ability to reduce to dihydronandrolone (DHN) rather than dihydrotestosterone (DHT). This makes Nandrolone one of the most well tolerated anabolic steroids for adult men. Nandrolone possess very little estrogenic activity with an aromatase rate of only 20% that of Testosterone. It is classified as an active progestin and this will play into potential side effects, but they are controllable in most cases.
