Drostanolone propionate is used primarily by athletes who need to keep strength while losing mass. It is beneficial to runners, athletes and fighters who must remain in a certain weight class. It has gained popularity in the bodybuilding community as a diuretic and muscle defining drug.
Individuals interested in using the drostanolone propionate are those that are looking to add muscle hardness and density to their physiques, nearly always for the purpose of bodybuilding competitions.
Drostanolone propionate can increase muscle hardness and density, giving an individual a more complete appearance when competing on stage. However, an already rather low body-fat level is needed for it to take full effect. Drostanolone propionate can promote increased strength while keeping body fat the same or even lowering it, it can also help to prevent muscle loss while dieting.
