Deca Durabolin androgenic/anabolic steroid (AAS) is easy on the liver and promotes good size and strength gains while reducing body fat. This drug is unique in that 5a -reductase, the enzyme which converts testosterone to the more-potent DHT, actually converts Nandrolone to a less-potent compound.

Since nandrolone is a progestinic anabolic steroid, some special precautions need to be taken to ensure that side effects do not get out of control as a result of a rise in prolactin levels. Using compounds such as bromcriptine, cabergoline and/or vitamin b6 have all been shown and reported to help lower prolactin levels. The drug femera (letrozole) is also effective for use with nandrolone as it will regulate the progesterone and estrogen receptors in the body, therefore preventing some of the negative side effects associated with the compound.

Deca Durabolin is also a popular steroid among female bodybuilders. They take a much lower dosage on average than men of course. Although only slightly androgenic, women are occasionally confronted with virilization symptoms when taking this compound. Should this become a concern, the shorter acting nandrolone Durabolin would be a safer option. This drug stays active for only a few days, greatly reducing the impact of androgenic buildup if withdrawal were indicated.

Endogenous testosterone levels can be a concern with Deca Durabolin, especially after long cycles. It is therefore mandatory to incorporate ancillary drugs at the conclusion of therapy. An estrogen antagonist such as Clomid or Nolvadex is therefore commonly used for a few weeks. These both provide a good level of testosterone stimulation, although they may take a couple of weeks to show the best effect. HCG injections could be added for extra reassurance, acting to rapidly restore the normal ability of the testes to respond to the resumed release of gonadotropins.

Remember not to begin post cycle therapy (PCT) until after Deca Durabolin has been withdrawn for around three weeks. Deca Durabolin stays active for quite some time so the ancillary drugs will not be able to exhibit their optimal effect when the steroid is still being released into the bloodstream. Small amounts may indeed be stubborn in leaving fatty tissue, particularly after heavy, longer-term use. Some quantity of nandrolone decanoate may therefore be left to sporadically enter into the blood stream many months after use.
