Nandolone decanoate is one of the most widely used and effective steroids on the market. Although not effective in producing lean muscle gains or fat loss, it is an all around great drug for muscle building, stackability, secondary effects, and its ability to maintain gains.

Deca is structurally very similar to testosterone with the difference being a missing carbon atom at the 19th position which gives Deca its other name, 19nortestosterone. This altered drug provides weaker androgenic effects than testosterone but it is also less likely to break down into androgenic metabolites which will cause male sex side effects like acne or hair loss.

Nandrolone only produces about 1/5th of the estrogen conversion of testosterone which translates into far less water retention, gynecomastia, or other estrogen related side effects.

Nandrolone has a very long half life of 15 days which translates into slow, steady gains of quality muscle. It binds very well to the androgen receptor effectively delivery its anabolic message and providing beneficial secondary effects.

The most well known secondary effect of deca is its ability to provide fluid for connective tissue and joints. This improved collagen production will elevate joint pain and add stability during heavy lifting allowing you to manage much heavier weight than normal.

Supplementing nandrolone has been shown to increase muscle building through a significant effect on positive nitrogen retention.
