Deca Durabolin cycles are considered the safest steroids in use today. It is because Deca has a less androgenic and more potent anabolic action. It does not bind to the scalp and therefore, is not associated with balding. Deca does not interact as much with the Aromatase enzyme and as a result, does not convert to Estrogen in large amounts. It is, therefore, not associated with gynecomastia or water retention. Despite this, Deca cycles are associated with some adverse side effects.
A Deca Durabolin cycle is associated with some form of aromatization. It is especially true when used at very high doses and for very long durations. Although Deca is primarily broken down to inactive compounds by a reductase enzyme, some of it undergoes aromatization. For this reason, there have been cases of gynecomastia, a tenderness of nipples after a Deca cycle. It is why the use of an Aromatase inhibitor during a Deca Durabolin stack is recommended. It ensures the risk of aromatization is eliminated.
Perhaps the most common side effect of a Deca cycle is the suppression of testosterone production. Although this occurs at a milder rate than with other steroids, it still happens. Deca inhibits the production of Luteinizing and Follicle-stimulating Hormones through negative feedback. These two hormones are responsible for commanding the Leydig cells of the testes to produce Testosterone. There is a reduction in testosterone levels in the body. It then leads to symptoms such as reduced libido, change in sleeping patterns, fatigue, reduced energy levels, and increased risk of developing low moods or depression. It is why you should stack Deca with Testosterone esters during a Nandrolone cycle. It makes sure there are enough levels of Testosterone in the body at all times.
Advanced female steroid users also use Deca cycles. They are associated with more adverse effects. Despite the low androgenic activity, women are susceptible to even the lowest levels of exogenous Testosterone. Women who use this cycle experience virilizing side effects. These include hirsutism, which means they get increased hair growth on their bodies in a male pattern, including the development of beards. Other effects include clitoral enlargement, deepening of the voice, and development of acne.
Regardless of these side effects, Deca Durabolin stacks are safer than most of the other anabolic steroid cycles that are in use. However, the severity of the side effects can be increased by the steroids that are used in a Deca Durabolin stack. As with other cycles, the use of post cycle therapy is necessary to reduce their occurrence, as well as sticking to the recommended safer doses and duration of use.
