Nandrolone Decanoate is the chemical name of active ingredient in Deca Durabolin. Deca Durabolin is widely regarded as one of the safest and effective steroids. Nandrolone Decanoate is commonly used as a base in a steroid cycle. Nandrolone Decanoate is an anabolic steroid that is both present in the human body and also made synthetic. The levels in the human body are very low to account for any significant effects. It is a byproduct when other hormones breakdown in our body. Of all the anabolic steroids, it is one of the most widely abused steroids by athletes and bodybuilders. Deca-Durabolin is an ideal bodybuilding agent for the following reasons: Nandrolone decanoate (Deca Durabolin) does not convert to DHT. Nandrolone decanoate (Deca Durabolin) has relatively low aromatization activity. Steroid users who are sensitive to estrogenic side effects find Deca-Durabolin a safe choice. Deca Durabolin is ideal as a pre-contest drug, commonly stacked with Winstrol and with non-aromatizing agents like Halotestin and trenbolone. Nandrolone Decanoate is proven to be a progestin. This fact is of clear importance in bodybuilding, because while moderate Deca-only use actually lowers estrogen levels as a consequence of reducing natural testosterone levels and thus allowing the aromatase enzyme less substrate to work with, Deca nonetheless can cause gyno in some individuals. Furthermore, just as progesterone will to a point increase sex drive in women, and then often decrease it as levels get too high, high levels of progestogenic steroids can kill sex drive in male bodybuilders, though there is a great deal of individual variability as to what is too much. Incidentally, this progestogenic activity also inhibits LH production, and contrary to common belief, even small amounts of Deca are quite inhibitory, approximately as much so as the same amount of testosterone. Side effects: Nandrolone Decanoate does have a wide range of side effects when it is used for a long time. When used at low doses, the side effects are rare and minor. Infact, except for bloating and nausea, most people do not notice anything significant. However, at high doses, the most common side effects include: atigue, tiredness weight gain water retention acne oily skin jaundice gynecomastia decreased libido testicular atrophy mood swings- depression, anger, aggressiveness loss of hair decrease HDL increase LDL jawbone growth The majority of these side effects reverse when the drug is stopped. Some of the side effects like oily skin and acne do persist for a few months after the drug is stopped. In females, the virilizing effects are not always reversible. Dosing: Nandrolone is available as a pill and also a liquid for injection. The pill formulations appear to have disappeared from the market and many bodybuilders had difficulty putting on weight with the drug. The longer acting nandrolone in injection form is used today by all bodybuilders. The oily liquid formulation should only be injected into the buttock area and this spot should be frequently rotated to prevent abscess formation. When large volumes are injected in the buttocks, there may be pain and a constant ache. The recommended dose of nandrolone decanoate is 50-100mg/week. If no effects are seen after 6 months of use, the drug must be discontinued. One should be aware that when no effects are seen after long term use of the steroid, one must suspect a fake formulation- which is not unheard of. Nandrolone liquid preparations do often breakdown and if the product is discolored or appears clumped it should not be used.
