Nandrolone decanoate is a nandrolone ester , or a prodrug of nandrolone .     As such, it is an androgen and anabolic steroid , or an agonist of the AR, the biological target of androgens like testosterone and DHT.     Relative to testosterone, nandrolone decanoate has enhanced anabolic effects and reduced androgenic effects.    It is considered to have strong anabolic effects but weak androgenic effects, with respective potency ratios of – and – (index value –) relative to testosterone propionate .   Along with oxandrolone , nandrolone esters are thought to have the highest ratio of anabolic to androgenic effects of any other AAS.  For this reason, they are considered to be among the most appropriate AAS for use in women.  Androgenic effects such as virilization are relatively uncommon at recommended dosages, though may still occur especially at higher dosages or with extended use.   The low androgenicity of nandrolone decanoate is thought to be due to the fact that whereas many other AAS like testosterone are potentiated via transformation by 5α-reductase in specific tissues like the skin , hair follicles , and the prostate gland , nandrolone is instead inactivated by 5α-reductase into the low-affinity AR ligand 5α-dihydronandrolone in such tissues.   
Many athletes, ball players, fighters, and any athlete who could benefit from the therapeutic relief often supplement with Deca Durabolin. Such individuals commonly have no desire to build any new lean muscle mass, but the relief alone is invaluable. Further, such relief can be obtained by a very low dose. A slightly higher dose will provide relief, greatly enhance overall recovery, and enhance muscular endurance. When it comes to performance enhancement, most athletes will find this steroid is hard to beat. More importantly, the relief effects of Deca Durabolin are not masking or false; this anabolic steroid shares nothing in common with over the counter painkillers or prescription painkillers like opiates. Such painkillers only mask the pain, whereas Deca Durabolin can actually heal the body.
A cutting Deca Durabolin cycle will normally not be built around this Nandrolone hormone, but rather it is a secondary addition. In the cutting phase, this steroid may be added to a total plan in order to promote muscle tissue preservation, but it is most commonly added for the therapeutic effects this steroid can provide. If a cutting Deca Durabolin cycle is implemented, especially if you’re a competitive bodybuilder, you will more than likely want to keep its use at the front end of the total plan and rely solely on hardening agents towards the end. This type of Deca Durabolin cycle cannot be recommended to new steroid users . This type of use will normally be extended beyond what a new steroid user will be comfortable with.
