Deca Durabolin is a powerful anabolic androgenic steroid. Perhaps one of the most used and top Deca Durabolin cycles is the bulking cycle. It can also be used as a cutting agent but most people prefer using it during periods of growth. This is befitting as Deca Durabolin causes a slow but sustained increase in muscle mass and growth.

The slow growth in muscle mass is important as it allows the body more time to adapt to the hypertrophy. This is through increasing vascular supply to the hypertrophic muscles. It also allows for the preservation of muscles once the cycle ends.

During a Deca Durabolin bulking cycle, stacking is usually done with testosterone, Arimidex and Dianabol. The Arimidex is an Aromatase enzyme inhibitor which prevents the breakdown of testosterone to Estrogen. Dianabol gives faster results in muscle growth and is used to jump start gains in this cycle. Testosterone is used to replace the suppressed endogenous Testosterone levels.

This bulking cycle usually lasts a total of 12 weeks. Testosterone is used at 500mg weekly, Deca Durabolin at 400mg weekly, Dianabol at 30mg everyday and Arimidex at 0.5mg every day. They are all used together for the first 6 weeks after which Dianabol is withdrawn and Deca Durabolin is withdrawn after 10 weeks. Testosterone and Arimidex are then continued for the final 2 weeks and act as post cycle therapy.

An advanced Deca Durabolin cycle has a stack of testosterone Cypionate at 200mg every other day for 16 weeks, Deca Durabolin at 500mg a week for 14 weeks, Dianabol at 50mg a day for 6 weeks, human growth hormone at 4IU every day for 16 weeks and Arimidex at 0.5mg everyday for the 16 weeks. This bulking cycle should be used by veteran steroid users.

A cycle should be combined with exercise and diet for greater results.
