Nandrolone Decanoate, commonly known as Deca, is an Anabolic Androgenic Steroid (AAS) that is used for many therapeutic uses. It has a positive influence on calcium and protein metabolism and increases the rate of cell synthesis, which has made it a common treatment for people suffering from Osteoporosis and other debilitating diseases. Deca also increases the body’s natural Collagen production, especially in cartilage, so it stimulates healing and reduces inflammation and pain in joints.

At a low dose, Deca can be used to treat these kinds of illnesses indefinitely with low risk of steroid-related symptoms. Deca has high anabolic effects, which is the increase of soft tissue growth, and low androgenic effects, to promote a major increase in muscle mass. The formation of muscle growth is caused by the tearing of myofibrils, the fiber strands that are bundled together to form a muscle. When these tissue fibers are damaged and torn the body repairs them with new fibers that are thicker, resulting in muscle hypertrophy, or the increase of muscle mass. The result of this process is greater strength and increased muscle size.
