nandrolone decanoate

Deca Durabolin (Nandrolone Decanoate) 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.

The unusual properties of Deca Durabolin are due to its parent steroid, nandrolone, also known as 19-nortestosterone. One of the principal positive qualities of nandrolone is that it has relatively low conversion to estrogen compared to testosterone.

In earlier years, testosterone and nandrolone were the only pharmaceutical injectables that were both widely available to bodybuilders and economical. Estrogen control did not then exist. For this reason, Deca’s low aromatizing properties were then quite useful. Deca therefore won wide popularity.

Since deca durabolin is formulated using nandrolone decanoate, one of the longest esters in existence, it is very oil soluble, the way all steroids with long esters are. This easy solubility in oils means that manufacturers have to use a lower percentage of solvents to manufacture the products; thus, making for a less irritating shot. Generally, deca injections are done weekly by most bodybuilders.
