Deca-Durabolin is the brand name of nandrolone decanoate, under which it was first produced by Organon. Today, many generic versions are available, with the same chemical properties but sometimes with different dosage. “Deca” is one of the most popular anabolic steroid among the bodybuilders, although it is almost always used together with other medicaments.
The main advantage of nandrolone is its mild androgenic action. It means it poses lower risk for side-effects like prostate hypertrophy, acne vulgaris or male-pattern baldness. Just as testosterone is forming dihydrotestosterone (DHT) in the body, which is a strong androgen, nandrolone forms dihydronandrolone (DHN), which is again much milder in its androgenic effects.
Nandrolone is considered to be 2.4 times more anabolic than testosterone, this, however, doesn’t really mean that your muscles will grow twice as fast or even twice as big when using this hormone. On the contrary, nandrolone is somewhat slow in its action, which is why it is usually stacked with Dianabol, Anadrol, Winstrol or virtually any other steroid.
The most important ways of action of Deca-Durabolin is nitrogen retention enabling amino-acid formation, glycogen storage and growth hormone release. Nandrolone decanoate also causes fluid retention in joints, which means that you will feel less pain in heavy workouts.
