Deca Durabolin (Nandrolone Decanoate) is an injectable anabolic steroid typically utilized by bodybuilders in the off-season for mass building.Deca Durabolin promotes muscular hypertrophy (size) and strength, causing significant changes in body composition after several weeks of use.

Deca Durabolin promotes lean mass by stimulating protein synthesis and creating a positive nitrogen balance inside the muscle cells.We have also found Deca Durabolin to increase collagen synthesis, improving the health of ligaments and tendons. This is particularly beneficial to bodybuilders and powerlifters who regularly lift heavy weights, thus making them more susceptible to injury.
