Masteron

Masteron being 5-alpha reduced, cannot form estrogen upon interaction with the aromatase enzyme yet still shows a very high affinity for it. Because it takes up so much of the aromatase enzyme, yet is refrained from actually using it by its structural make-up, it reduces the amount of estrogen formed from other steroids as well because there are less aromatase enzymes to be used by those compounds to form estrogen with (1). However most will find that drostanolone is too expensive to employ it for that reason alone, especially when compounds such as Proviron are available for the same purpose at much lower costs.

Masteron can increase muscle hardness and density, giving an individual a more complete appearance when competing on stage. This is an effect that a lot of pure androgens will exhibit. But with all of them you need an already rather low body-fat level for it to take full effect. If this is done, drostanolone can promote increased strength while keeping body fat the same or even lowering it, something can help to prevent muscle loss while dieting. This can also allow strength athletes or those athletes in sports which have weight classes to increase performance without the risk of being raised into a higher weight class or add mass that may hinder performance.
