Deca Durabolin is one of the anabolic steroids most favorable for side effects for men and may be beneficial for women, but usually only at therapeutic levels. However, the side effects of Deca Durabolin certainly exist, but as we will see, they are largely within the realm of possibility, rather than guaranteed. When used responsibly, most men will be able to use this steroid without any first negative effect. To reach this level of safe supplementation, your first step is to recognize the possible side effects of Deca Durabolin and what you can do with them.    For ease of understanding, we have divided the side effects into separate categories, along with related information that you will need.


The hormone nandrolone is not very estrogenic, but has a light aromatizing nature. Aromatization refers to the ability of testosterone to convert to estrogen, a process that occurs due to the interaction of a hormone with the aromatase enzyme. Increased estrogen levels can contribute to gynecomastia, excessive water retention, and high blood pressure due to strong water retention. Fortunately, Deca Durabolin aromatase levels are low, but there is another factor to consider, namely its progestin nature. Nandrolone has a strong affinity for the progesterone receptor as well as the ability to significantly stimulate the estrogenic mechanism in breast tissue, increasing the risk of gynecomastia.    

To protect yourself against the possible estrogen and progesterone side effects of Deca Durabolin, anti-estrogen medications are often recommended . There are two main variants of antiestrogens: selective estrogen receptor modulators (SERMs), such as nolvadex ( tamoxifen citrate), and aromatase inhibitors (AI), such as arimidex ( anastrozole ). AIs will be much more efficient, but SERMs should be the first choice if they can get the job done. Many people choose to rely on AI for its immense anti-estrogenic power, but it has been noted that AI has a negative effect on cholesterol and this can be very annoying for anabolic steroid use. Conversely, while SERMs are sometimes insufficient, they do not have an adverse effect on cholesterol. In fact, SERMs have been shown to improve cholesterol levels.

Deca Durabolin may cause androgenic side effects; however, for most men, this threshold is usually quite high. Possible androgenic side effects of Deca Durabolin include acne, accelerated hair loss in individuals prone to male pattern baldness, and body hair growth. These side effects are highly dependent on genetic predisposition, but most men should not show any problems. Unlike testosterone, nandrolone is reduced to DHN, not DHT, and although this is due to interaction with the 5-alpha reductase enzyme, it significantly reduces the androgenicity of nandrolone.    

The androgenic nature of Deca Durabolin can lead to virilization symptoms in women. Virilization symptoms can include body hair growth, deepening of the vocal cords, and enlargement of the clitoris. Women can use this steroid without virilizing effect, but very low doses are required and often women can choose the best steroids. If nandrolone is desired, the faster-acting phenylpropionate can be used as it is easier to control, but the chances of defeating virilization symptoms are not as great as with steroids such as Anavar or Primobolan . In any case, if symptoms of virilization occur, discontinue use immediately and they will disappear. If you ignore these symptoms, they can become permanent.     


Deca Durabolin may have a negative effect on cholesterol by distorting the HDL to LDL ratio. This potential negative effect will be most noticeable as it relates to the suppression of HDL cholesterol. Research has shown that the hormone nandrolone actually has a stronger negative effect on HDL cholesterol than testosterone. However, the total cardiovascular stress should be much less than that of most oral steroids.   


Deca Durabolin , like all anabolic steroids, suppresses the production of natural testosterone. The rate of suppression varies from one steroid to another, but with Deca Durabolin and all nandrolone based compounds it will be extreme. Some studies have shown that a single 100 mg steroid dose suppresses total natural production. Other studies, while not showing nearly suppressive rates, are still more than significant and often reflect at least 2/3 of the total decrease in serum testosterone levels. For this reason, all men taking Deca Durabolin must include exogenous testosterone.     

After the use of Deca Durabolin has come to an end and all the exogenous steroid hormones have cleared your system, natural testosterone production will begin again. This will not happen overnight, and for this reason a post cycle therapy (PCT) plan is often recommended . This will speed up the recovery process as well as improve overall efficiency. No, contrary to popular myth, there is no PCT plan that will by itself bring your natural testosterone levels back to normal. Full recovery will take several months. However, a PCT plan will ensure that you have enough testosterone to function properly, while your levels continue to rise naturally.     

Important Notes About Natural Testosterone Recovery After Using Deca Durabolin : Natural Recovery suggests that there was no prior low testosterone condition. It is also assumed that the hypothalamus-pituitary-testis (HPTA) axis has not been seriously damaged due to improper practice. It is also important to note that the PCT plan should not be started until Deca Durabolin has been stopped for at least 2-3 weeks. The majority considers that the cessation of Deca- Durabolin to the completion of the cycle will be the best solution.
