Masteron 200 in bodybuilding

Masteron 200 in bodybuilding

Masteron 200 can be called the undisputed champion in muscle drying amongst steroids, because, he has a very special set of qualities that make him the best combining steroid for other anabolic androgenic steroids (AAS) . The absence of estrogenic manifestations, insignificant side effects, and pronounced muscle hardening are just some of the reasons why the masteron is so popular. In the expanses of the former CIS, he is also known as Drolban, Metormon, and Permastril.


Masteron (chemical name Dronostanol) was established in 1959, and went on sale in 1970. Initially, it Masteron 200was developed and sold by Syntex Pharmaceuticals, the same company that created Anadrol. Drostanolone was sold under various names until Eli Lilly acquired the right to manufacture this substance, and did not sell it under the trade name Drolban.

At first it was used to treat breast cancer, but nowadays the medical community has come to the common opinion that the masteron is not effective enough to treat cancer. There are still cases when it is used for this purpose, and moreover, the US Food and Drug Administration (FDA) did not prohibit the use of a masteron for the treatment of breast cancer. Despite this, nowadays drostanolone is used almost exclusively by bodybuilders.

Doping control

For a long time the master was very popular among athletes because his presence was not checked during doping controls. However, in the early 90’s, tests were introduced that could detect drostanolone, thereby restricting its use immediately before and during the competition.

Masteron in the role of anti-estrogen

There is a generally accepted view that masteron is an anti-estrogen drug. However, this is only partly true. Masteron 200 really lowers the level of estrogen in the blood, but in fact, this is a side effect that occurs because of the chemical structure of the substance. Masteron is a derivative of DHT, so it can not be converted to estrogen. However, it still blocks the enzymes of aromatase, leaving less available enzymes to interact with testosterone and its conversion to estrogen. In fact, its anti-estrogenic activity is similar to that observed in Proviron. Therefore, the masteron is so popular for combination with flavoring steroids.

Drostanolone exhibits excellent synergy with such steroids as testosterone and dianabol, reducing water retention and giving a better quality muscle mass.

Side effects Masteron 200

Side effects Masteron 200

As already mentioned, the master has no estrogenic manifestations. So such side effects as vzbuchivanie, water retention, high blood pressure, and gynecomastia will not be a problem when using this steroid.

Drostanolone is available exclusively as an injectable steroid, so it is not 17-alpha-alkylated. Therefore, it is not toxic to the liver, and even with prolonged courses it does not have any effect on this organ.

Like most steroids, Masteron 200 suppresses the natural production of testosterone. Therefore, after the course therapy (PCT) is always necessary.

Hair loss

Masteron 200 is a strong androgen, and problems such as oily skin, acne, increased hair growth on the face and body, and accelerated hair loss can occur. Due to the fact that it is a derivative of DHT, such drugs as Proscar and / or Propecia will not help in the fight against hair loss during the application of the masteron. For this reason, those who have a predisposition for baldness should be careful with this steroid.


A high level of androgen activity of the masteron creates problems for women. Despite the fact that there are athletes who use the master in the role of a pre-competitive drug, this is very risky because of the symptoms of virilization that may manifest. The risk of their occurrence is very high, and they will acquire a pronounced effect very quickly.

The same women who dare to use the master, should not exceed a dosage of 50 milligrams (mg) per week.

Dosage and administration

On average, the weekly dosage for athletes is 300-400 mg, and more advanced bodybuilders take up to 500-600 mg per week. Soft side effects of the master can be taken up to 1000 mg per week, but such excessive doses do not make sense.

The schedule of injections will strongly depend on the ether of drostanolone. If the choice fell on propionate, injections should be done every other day. If droostanolone enanthate is used, it will be enough to inject once a week.

DrostanoloneDrostanolone is mainly used for drying muscles to give the musculature additional hardness and relief before the competition. However, there is one important nuance that must be borne in mind. In order to get the most from the capabilities of the master for drying and hardening, the body fat level should not exceed 10-13%. Moreover, there will be no particularly visible results if the athlete does not have a certain muscle mass.

Due to its anti-estrogenic properties, the masteron 200 is simply ideal for combining with other steroids. For drying, it can be combined with Winstrol , Primobolan , or Anavar. In this case, the typed muscles will be of exceptional quality without the delay of water or fat. In addition, drostanolone can be used in courses for weight gain. For this, it can be combined with Dianabol or injectable testosterone. This combination will help to add quality to the typed mass, and partially suppress side effects of estrogenic nature.

Of course, the master can be used alone. But in this case his tremendous synergetic abilities will be wasted. Moreover, weight gain will be stable, but it can not even be called close to massive. Nevertheless, the weak side effects and ease of use make a master steroid an excellent steroid for lovers who do not expect an extreme increase in weight.

Half-life (half-life)

The half-life of propionate lasts from 3 to 4 days. In this case, he will stay in the body for about 3 weeks. So it is necessary to take precautionary measures if doping control is planned

Masteron Enantat

The half-life of enanthate lasts 8-10 days, and in the body it will remain for about three months. Therefore, his reception should be interrupted for 3-4 months before doping control.

There is an opinion that masteron propionate is completely safe, if its application is completed 3-4 weeks before the competition or doping control. Nevertheless, etheric steroids have a tendency to remain in the body for a very long time, which is difficult to predict.


Masteron 200 is a very safe steroid, which is mainly used to add rigidity and relief to the musculature before the competition. To get the most out of his capabilities requires a certain physical form, namely, a low level of body fat and a relatively large muscle mass.

However, this is one of the best combination steroids for other AAS, because, it can reduce estrogenic manifestations. It is because of its ability to suppress estrogenic effects, and to add quality to muscle mass, that the masteron is often used in mass gain courses.

The masteron has very few side effects, most of which are associated with its high androgenic activity. With this steroid, estrogen is not at all a problem, and accordingly, such ailments as swelling and gynecomastia never manifest themselves during the reception of the masteron. Similarly, it does not lead to high blood pressure, which makes it very tolerable for the cardiovascular system.

In general, this is an exceptional steroid that works in synergy with other AAS. So the best results are achieved by combining it.
