Nandrolone decanoate is a popular steroid which is structurally similar to testosterone, minus a carbon atom at the 19th position. This creates a steroid that exhibits less androgenic properties compared to that of Testosterone, resulting in the conversion to a weaker metabolite- dihydronandrolone, not DHT. Androgenic related side effects are still possible, but are likely to be of a less occurrence compared to that of the likes of testosterone. The compound is usually referred to as 'deca' as deca-durabolin was the brand name by Organon for their nandrolone decanoate.
Nandrolone decanoate has been shown to have a lower tendency to convert to oestrogen. Oestrogen related side effects are possible, but are usually confined to those who use excessive dosages of the steroid, or those who are sensitive to such side effects.
What is of a concern however is nandrolone decanoates activity of a progestin, as being shown to have some affinity to the progesterone receptor. This can lead to progestin like side effects, which are actually similar to that of oestrogen related side effects. This can be an issue among bodybuilders as the side effects can be easily be mistaken as oestrogen related side effects and thus many try the usual anti-oestrogens for treatment, to little effect. Progesterone does need oestrogen to activate it however, so the inclusion of a competitive aromatase inhibitor, such as arimidex, will aid to keep oestrogen levels low to avoid activation of the progesterone. This method is more of a prevention method however, as it will do little for already progesterone induced gynecomastia.
On a competitive note, nandrolone decanoate shows many popular characteristics. The major draw back of nandrolone decanoate use however is its ability to stay in the system for a long time after administration. Being an esterified compound, the nandrolone decanoate can possibly still be released into the blood stream many months after use from fatty tissue in which esterified steroids can often stay stored. This process can be magnified when the athlete reduces body fat levels for a show, as more fatty tissue is being reduced, thus possibly freeing up the substance.
