The optimal dosage of Deca Durabolin is 200 – 600 mg a week. As stated by many experts in the field of sports pharmacology, the greatest effect brings the dosage at the rate of 4 mg per kilogram of body weight of the athlete in a week. The use of Nandrolone Decanoate at a dose of less than 200 mg usually leads to a very weak anabolic effect, which is greatly enhanced with increasing doses. I must say that the performance from the reception of the soundboard directly proportional to the quantity of its use at the same dosage over 600 mg per week will contribute to the opposite effect, that is, the side effects will be more acute. As stated by many of the “chemists”, beginners is enough 200 mg a week to get the desired result.
On the black market Deca remains one of the most popular anabolics in circulation. Currently 200mg/ml preparations from Mexico are dominating the marketplace, and due to their high availability and lower cost are minimizing the appearance of lower dosed compounds. For example, in addition to Norandren 200 Brovel also makes Norandren 50 (a 50 mg/ml version of this steroid), but it is almost unseen right now. I should point out that their 50m1 vial of Norandren 200 is also the largest container of nandrolone to be found in such strength, and represents one of the best values anywhere for this steroid. We can see why it is much more desired right now. Also common are Nandrolona 200 from Tornel and Decanandrolen from Denkall, both in 1 Oml vials. In an effort to provide more innovative, conspicuous and cost-effective products, the Mexican firm Ttokkyo has recently topped its competitors and released Nandrolona 300. This is a 300mg/ml preparation of nandrolone decanoate, which is by far the highest dose of this compound ever to be produced commercially. To spite the defiant opinions of many, indeed this is a legitimate product. I have not experimented with the solubility of nandrolone decanoate myself, but do know that this particular ester is highly fat-soluble. Reaching 300mg in a milliliter of oil does not seem like an unreasonable or impossible task, and I would guess requires at best some minor tweaking of alcohol levels (perhaps none at all).
There are possible estrogenic side effects of Nandrolone despite it not being a very estrogenic hormone, at least not directly. Nandrolone does aromatize slightly. Aromatization refers to the conversion of testosterone to estrogen . This takes place when the testosterone hormone interacts with the aromatase enzyme. When the conversion takes place this can cause estrogen levels to go up, which can promote gynecomastia and water retention. High blood pressure can also become an issue if water retention becomes severe. Along with the low level of aromatase activity Nandrolone is also a progestin and has a strong binding affinity for the progesterone receptor. This may stimulate the mammary tissue and enhance the risk of gynecomastia in sensitive individuals.
Combating the estrogenic side effects of Nandrolone can be achieved by the use of anti-estrogen medications, specifically Aromatase Inhibitors (AI’s) such as Anastrozole ( Arimidex ). Selective Estrogen Receptor Modulators (SERM’s) are also sometimes used, such as Tamoxifen ( Nolvadex ). However, AI’s are the proper choice as they will directly reduce serum estrogen levels and SERM’s will not. An AI should be enough to reduce and avoid gynecomastia unless the individual already has existing gynecomastia that could potentially be exasperated.
Important Note: It’s often been said that Nandrolone based gynecomastia is based on increases in prolactin. It is true that 19-nor steroids can increase prolactin, which can also negatively affect libido and erection function. Some men may need to use a dopamine agonist to combat this. However, it is not prolactin that causes 19-nor based gynecomastia but rather the imbalance between estrogen and progesterone. If you merely combat prolactin you may find yourself with the very gynecomastia you tried to avoid.
