Masteron is a Dihydrotestosterone derivative, which prevents it from being aromatized into Estrogen by the aromatase enzyme. This is the enzyme responsible for the conversion of androgens into Estrogen . Furthermore, Masteron has been found to be a proven moderate aromatase inhibitor, serving to disable the aromatase enzyme and reduce Estrogen levels as a result. Therefore, one can expect very solid lean muscle gains without any water retention, and minimal fat gain/retention (provided the user has accompanied their cycle with an appropriate diet). The primary purpose of Masteron among athletes and bodybuilders is to exert its aesthetic e enhancing effects of the removal of subcutaneous water retention (due to its anti-aromatase and anti-estrogen activity). Masteron serves as a very poor mass builder with its moderate anabolic strength rating. It is best utilized stacked with other compounds, as Masteron itself is not that much stronger than Testosterone , and in some cases may be weaker. However, when stacked with Testosterone or any other anabolic steroids, it serves to contribute a couple of amazing features to any cycle that makes the other compounds it is stacked with more powerful.
The side effects of Nebido can include those of an androgenic nature. The androgenic side effects of Nebido are, however, highly dependent on genetic predispositions and will not affect all men. The possible androgenic side effects of Nebido include accelerated hair loss in those predisposed to male pattern baldness, acne in sensitive individuals and body hair growth.
While by no means always necessary, some men may find the use of a 5-alpha reductase inhibitor to be useful. The testosterone hormone is metabolized by the 5-alpha reductase enzyme, which reduces the testosterone hormone to dihydrotestosterone (DHT). The DHT is what leads to the androgenic related effects. By incorporating a 5-alpha reductase inhibitor, you will reduce the hormones androgenicity. It will not be a complete reduction, but it will be significant. However, such inhibitors are not always recommended and should only be used as needed as they can hinder the potency of the testosterone hormone.
