Nandrolone or trenbolone

Some bodybuilders and athletes use trenbolone esters for their muscle-building and otherwise performance-enhancing effects. [5] Such use is illegal in the United States and many other countries. The DEA classifies trenbolone and its esters as Schedule III controlled substances under the Controlled Substances Act . [18] Trenbolone is classified as a Schedule 4 drug in Canada [19] and a class C drug with no penalty for personal use or possession in the United Kingdom . [20] Use or possession of steroids without a prescription is a crime in Australia . [21] The infamous "duchess" cocktail allegedly administered to Russian athletes at the Sochi Winter Olympics consisted of oxandrolone , a metenolone ester, and a trenbolone ester. [22]

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.
 

Trenbolone is without a doubt one of the most beneficial anabolic steroids on the market. When we consider the therapeutic benefits of Nandrolone, or even Testosterone, it may not quite match up but on the basis of raw power and physique transformation Trenbolone Acetate is the king. No steroid will be as beneficial when cutting, not even close, and when bulking it is nothing short of fantastic. While Tren is beneficial during cutting and bulking phases, if you’re only going to use it in one phase always choose cutting. Many will actually need to limit their Trenbolone Acetate use to one phase due to the harshness of the compound in some men, especially when we consider cardiovascular strain. However, solid responders who are in excellent health should find they can use the steroid during both phases with a high level of success.
