2.  Product description:
Masteron is an injectable preparation containing the steroid drostanolone propionate. Drostanolone is a derivative of dihydrotestosterone, most specifically 2alpha-methyldihydrotestosterone.
As a result, the structure of this steroid is that of a moderate anabolic/potent androgen which does not aromatize to estrogen. Water retention and gynecomastia therefore do not come into play with this drug. Masteron may in fact exhibit anti-estrogenic activity in the body, competing with other substrates for binding to aromatase. This would reduce the conversion rate of other steroids, Masteron acting in the same way as the oral steroid Proviron.
Bodybuilders have a strong like for non-aromatizing androgens, and find Masteron very useful in a cutting phase. It is generally used for a number of weeks prior to a competition, in an effort to bring out an improved look of density and hardness to the muscles. As long as body fat percentage is low enough, Masteron should work very well.
Provided everything fits as if should, the user can achieve that "ripped" look so popular to professional bodybuilding. The androgenic effect can also be crucial during this period, a time when caloric intake is drastically lowered. The user is provided added "kick" or "drive" to push through the grueling training sessions leading up to the show.
Masteron could of course be used during cutting phases of training as well. A cycle of this drug combined with Winstrol, Primobolan or Oxandrolone should provide great muscle retention and fat loss, during a period which can be very catabolic without steroids. It is an added benefit that none of these steroids aromatize, and therefore there is no additional worry of unwanted water and fat retention.

3. Applications:

High Purity Dromostanolone Propionate/Masteron/Drolban/CAS No: 521-12-0
Drostanolone propionate is used primarily by athletes who need to retain strength while losing mass. It is beneficial to runners and athletes who must remain in a certain weight class.
Drostanolone propionate can increase muscle hardness and density, giving an individual a more complete appearance when competing on stage.
Drostanolone propionate can promote increased strength while keeping body fat the same or even lowering it, something can help to prevent muscle loss while dieting .

4.Who Uses Drostanolone Propionate?

Within bodybuilding, weight lifting and other sports communities, the use of Drostanolone propionate is valued for its assistance in building harder muscle mass and increasing overall muscle density. As a result, the androgenic steroid is particularly desirable among individuals looking to improve their overall muscular strength without "bulking up" excessively or increasing muscle mass. In addition, the use of Drostanolone propionate is popular among bodybuilding enthusiasts, as regular use of the steroid can create a more chiseled physique by helping to build denser musculature.


Drostanolone propionate is particularly useful for athletes in competitive sports with weight groups, such as mixed martial arts, wrestling or other combat sports. The steroid can actually improve muscular strength while maintaining or even lowering overall body weight due to body fat. As a result, competitors using the steroid can typically stay in their weight class without difficulty.


6.Regulation & Certification

Given Drostanolone propionate's history as a breast cancer drug, it should come as no surprise that the steroid has been tested and approved by the Food and Drug Administration. Like all steroids with FDA approval, it should be taken in accord with the recommended dosages to ensure safe and effective results, with minimal side effects. FDA testing of Drostanolone propionate found no serious side effects, either when taken solely or in combination with other drugs.
