Forms of Drostanolone Propionate

In addition to Drostanolone propionate, a secondary form, known as Drostanolone enanthate, is also frequently sold under the same generic name. The latter form is slower-acting than Drostanolone propionate. However, Drostanolone propionate also needs to be injected daily for optimal effects.


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.


Drostanolone Propionate vs Others

Compared with many other steroids, Drostanolone propionate does not undergo aromatization (or conversion to estrogen). In addition, it does not convert to DHT and is unalkylated, meaning that it does not cause any negative side effects to the liver. Compared with other anabolic steroids, Drostanolone propionate is at least as effective as other common steroids for fat loss and muscle mass gain, and even more effective at “hardening’ musculature.



Drostanolone propionate helps to harden musculature while cutting body fat. However, it works most effectively among individuals who already have extremely low body fat levels. As a result, it may be most useful to use the steroid once you have achieved a body fat level of 10 percent or less, to cut the last bit of excess fat.


Additional Considerations

When used among active athletes and bodybuilders, Drostanolone propionate typically functions ideally. If you are taking a break from regular training, however, bear in mind that the steroid may have negative implications. Maintaining a healthy diet and exercise regime is critical to healthy Drostanolone propionate use, to maintain healthy cholesterol levels and overall wellness.


How It Works?

Drostanolone propionate is an injectable steroid, which is the primary means of taking it. Users may take Drostanolone propionate either alone or in a “steroid stack”, in combination with Dianabol or other steroids. As a non-aromatizing steroid, it is also frequently taken within a steroid cycle alongside a moderate degree of aromatizing steroids, to help offset the estrogen produced.


When to Use?

Drostanolone propionate is most often used during a “cutting phase” or “cutting cycle.” This period, often in the weeks before a bodybuilding competition or other sport event, is useful toward refining the look of hardness and density of the musculature. Taking the steroid during this period helps, as long as the overall body fat has been sufficiently lowered prior to the “cutting phase.”


What to Expect?

One of the major attractions of Drostanolone propionate is its non-aromatizing quality. As a result, any side effects are typically quite mild. Users needn’t be concerned about water retention, gynecomastia, blood pressure spikes or liver toxicity.

The androgenic nature of Drostanolone propionate accounts for most of the tell-tale signs and physiological changes associated with its use. Body hair growth and a deepening of the vocal chords may occur. However, most of these and related symptoms only occur with relatively high dosages of the steroid.

Drostanolone propionate has been on the market since the 1970s. While it was initially used in breast cancer treatment, it was quickly taken up by the bodybuilding community as an aid to performance. Since early production by Syntex, the steroid has since been produced by a series of other pharmaceutical companies, usually under the trade name, Masteron.


Customer Reviews

As attested by its low level of side effects, Drostanolone propionate is often considered a relatively low-impact anabolic steroid. However, it may be considered “weak” or “light” because it triggers relatively little growth in muscle mass. Nonetheless, its usefulness in increasing muscle density makes it an extremely effective choice for individuals with specific bodybuilding or other athletic needs.


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.



In addition to its scientific name, Drostanolone propionate is frequently referred to by a range of brand names and slang names. These include masteron, mastabol, mast or masto. Drostanolone enanthate, which may be called by the same slang names, is in fact a distinct steroid.


Customer Testimonials

Users of Drostanolone propionate typically praise the steroid’s effectiveness in meeting specific, targeted goals. Praise is also typically centered on the relatively low incidence of side effects. In addition, the ease of defining musculature while cutting or maintaining weight is a regular point of satisfaction among users.
