Deca 300 is a tremendously powerful anabolic steroid that is extremely popular, it is synonymous with mass, as off-season bulking cycles are its most common point of use. It is a fantastic bulking steroid, but what makes it even more special is its extremely high level of toleration. Healthy adult men who understand how to supplement with Deca 300 will almost never have a problem; sure, individual response will dictate quite a bit, but if problems arise it's almost always due to a lack of knowledge and understanding.
First of all, Deca Durabolin (and Nandrolone in general) doesnt produce many estrogenic or androgenic side effects. This is because Deca Durabolin has a very low rate of aromatization (conversion to estrogen via the aromatase enzyme), roughly equal to 20% the rate of Testosterone.
Deca is a very nice anabolic, causing nice slow gains in quality muscle. This could be due to its moderately strong binding to the Androgen Receptor, or its many positive non-Androgen-Receptor mediated effects. One such effect is nitrogen retention, which is a major factor in muscle growth and lean mass gains; in one study, with low-doses (65 mg/week) and high-doses of Deca (200 mg/week), both low-doses and high-doses resulted in significant nitrogen retention representing gains of 0.5 to 0.9 kg lean tissue/week and body weight increased by 4.9 +/- 1.2 kg, including 3.1 +/- 0.5 kg lean body mass, and treadmill exercise performance (cardiovascular fitness) also improved. The average dosage recommendation being 400-600mgs/week for muscle gain.
