Nandrolone increases protein synthesis in the body and greatly increases nitrogen retention. This marked anabolic activity makes it a favorite for bodybuilders. Nandrolone is often used to treat conditions of anemia and muscle wasting syndrome. Due to its reputed ability to help joint pain, it is often times injected directly into joint capsules to enhance tissue repair and stimulate connective tissue fluid to lubricate the joints.

Muscle gains are typically leaner than with testosterone. Deca Durabolin is one of the most popular anabolic steroids in the world due to its efficacy and good safety profile. Anabolic steroids are a Category III controlled substance in the United States.

If that wasn’t enough, 17-BOL, another formula from Avry Labs sold as a called The Mass Stack with the M1-BOL adds more anabolic/androgenic activity to the equation. The active ingredient of 17-BOL is called Stenabolin, which contains the ultra-potent prohormone Androst-5-en-3β-ol-17-one, that is anabolic/androgenic on its own, yet powerfully increases testosterone production through direct naturally occurring conversion processes in the body.
