Nandrolone Decanoate is a highly anabolic (muscle building) and moderately androgenic due to nandrolones chemical structure it only converts to estrogen slightly, at about 20% the rate of testosterone so estrogenic effects are not a major concern. Of note, however side effects are still possible, though rare and the development of breast tissue in males (gynecomastia) has been reported. One of the most popular anabolic steroid used in bodybuilding cycles, nandrolone is also (medically) used to treat severe debility or disease. It promotes tissue building processes, reverses catabolism (muscle destruction) and stimulates red blood cell production. Which makes it a very useful drug to treat wasting disorders such as advanced H.I.V. and also, makes it highly sought after by bodybuilders and athletes.
It increases levels of serotonergic amines in the brain, these chemicals contribute to aggressive behaviour, which could help athletes to train harder and improve speed and power. Nandrolone also increases levels of IGF-1 in muscle tissues. This may be another way that makes nandrolone highly anabolic and also seems to be a promising fat loss agent, men given the drug had reduced levels of under skin fat tissue, visceral (gut) fat loss was not as good however. The fat loss effect seems though to be dose dependent. The more you use, the more results you’ll get, with regards to this drug.
