Drostanolone Propionate is a dihydrotestosterone (DHT) derived anabolic steroid. Specifically, Masteron is the DHT hormone that has been structurally altered by the addition of a methyl group at the carbon 2 position, This protects the hormone from the metabolic breakdown by the 3-hydroxysteroid dehydrogenase enzyme, which is found in the skeletal muscle. It also greatly increases the hormone's anabolic nature. This simple structural change is all it takes to create Drostanolone, and from here the small/short Propionate ester is attached in order to control the hormone's release time. Drostanolone Enanthate can also be found through some underground labs, which does not have to be injected as frequently, but it is somewhat rare compared to the Propionate version. The majority of all Masteron on the market will be Drostanolone Propionate.

On a functional basis, Masteron is well-known for being one of the only anabolic steroids with strong anti-estrogenic properties. Not only does this steroid carry no estrogenic activity, but it can actually act as an anti-estrogen in the body. This is why it has been effective in the treatment of breast cancer. In fact, the combination of Masteron and Nolvadex (Tamoxifen Citrate) has been shown to be far more effective than chemotherapy in the treatment of inoperable breast cancer in postmenopausal women. This also makes it a popular steroid among bodybuilders as it could actually prohibit the need for an anti-estrogen when used in the right cycle. This will also prove advantageous during the cutting phase due to the hardening effects it can provide.

Without question, the effects of Masteron will be displayed in the most efficient way during a cutting cycle. However, for the effects to be truly appreciated the individual will need to be extremely lean. This is why the hormone will most commonly be found at the end of bodybuilding contest prep cycles as the individual should already be fairly lean at this stage. The added Masteron will help him lose that last bit of fat that often hangs on for dear life at the end of a cycle. It will also ensure his physique appears as hard as can be. Of course, the anti-estrogenic effect will simply enhance this overall look. For those that are not competitive bodybuilder lean, it is possible that the effects of Masteron may not be all that noticeable. The individual who is under 10% body fat should be able to notice some results and produce a harder, dryer look, but much over 10% and the effects may not be all that pronounced.


Masteron is often an ideal choice for inclusion in a steroid stack, or in some cases for use as the sole injectable for a steroid cycle. An enanthate ester version having a half-life of probably 5 days has become available. This version of Masteron may be injected as infrequently as twice per week.

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. It 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.


Pharmaceutical material, steroid hormone, anabolin.As a male hormone and anabolic hormones.Product features originally developed to combat breast cancerand thats exactly what masteron was developed and used for).Along a similar line, being a dht derivative, its got a very nice ability to add muscle hardness to an already lean physique.Drostanolone propionate helps eliminate fat as well (if not better) than much more highly scored androgens, in part due to its being a derivative of dht.Masteron is derived from dht, could be used as an anti-estrogenic drug, clearly it doesn't convert to estrogen and actually works to reduce it in your body, can possibly cause hairloss and other dht-related sides, is great for all types of athletes and bb'ers, but not women in high doses, it stacks well with almost anything, is very androgenic, awesome for losing fat and getting it's no surprise that it's many people's favourite steroid

Masteron Dosage

The average weekly dosage for male athletes is 300-400 mgs per week,

with experienced bodybuilders using up to 500-600 mgs weekly.

The mild side effects of masteron allow to take dosages as high as 1000 mgs per week, but such dosages are not really necessary.
