Nandrolone decanoate, by Organon.

Deca Durabolin is an injectable preparation containing the active ingredient nandrolone decanoate (popular trade name for deca durabolin).

Deca durabolin is a favorite to thousands of steroid users. It is easy on the liver and promotes good size and strength gains while reducing body fat.

Nandrolone is used in the treatment of osteoporosis (i.e., bone degeneration) due to its positive influence on calcium metabolism and the increase in bone mass. It also has a positive effect on protein metabolism and is used where a protein deficiency exists, eg. during chronic debilitating diseases, after major surgery & severe trauma.

Deca Durabolin - Decabolic's large popularity can be attributed to its numerous possible applications and, for its mostly positive results. The distinct anabolic effect of nandrolone decanoate is mirrored in the positive nitrogen balance. Nitrogen, in bonded form. is part of protein. Deca Durabolin causes the muscle cell to store more nitrogen than it releases so that a positive nitrogen balance is achieved. A positive nitrogen balance is synonymous with muscle growth since the muscle cell, in this phase, assimilates (accumulates) a larger amount of protein than usual.
