Drostanolone, which entered the pharmaceutical market in 1970 under the trade name of Masteron, is an anabolic androgenic steroid. As a therapeutic drug, Drostansterone Masteron has achieved good results in the treatment of breast cancer in postmenopausal women. When used as a bodybuilding performance-enhancing steroid, it is often used in a fat-reducing cycle. In fact, this is also the most widely used drotanosterone Masteron. Although Drostansterone Masteron is approved by the FDA, unfortunately almost all the brands that produce this drug are discontinued. But even so, Drostansterone Masteron still plays a very important role in the fat loss cycle used by competitive bodybuilders.


Functions and properties:

Masteron male value: 25-40 anabolic value: 62-130

Masteron is a class of anabolic steroids derived from dioxytestosterone. Specifically, a methyl group has been added to its second carbon position, which prevents it from being broken down by enzymes in skeletal muscle in the body. At the same time, its anti-inflammatory and anabolic functions have also been greatly improved. Drostanolone Enanthate sometimes appears on the market, it does not need to be injected so frequently, but it is much rarer than Drostanolone Propionate. Most of the Drostansterone Masterons in the market are still Drostansterone Propionate.


Due to its structural characteristics, Drostansterone Masteron is the only anabolic steroid with antiestrogenic properties. This allows bodybuilders to avoid the use of anti-estrogens by using drotandrosterone Masteron in a suitable cycle. At the same time, it can make the muscles firmer and make drotanosterone Masteron have a good effect in the fat loss cycle.


Although the anabolic and androgenic ratio of drotandrosterone Masteron is not high, in fact these data are misleading. Remember that the androgenic power of drotandrosterone, the basic constituent of dioxytestosterone, is five times stronger than that of testosterone. This means that it can increase the efficiency of fat metabolism while improving muscle stiffness. Not only does it increase overall metabolic efficiency, its powerful androgenic properties also directly induce lipolysis.

Anabolically, drotasterone Masteron does not have strong muscle-building properties, but it can improve strength, which is useful for some competitive athletes who do not need to increase mass.




There is no doubt that the most suitable stage for Drostansterone Masteron to work is in the fat loss cycle. However, the premise of using it is that the user's sebum must be very low. That's why the hormone is often used towards the end of the race preparation phase, when the athlete is already low in body fat. Drostansterone Masteron can help get rid of every last bit of stubborn fat. If your sebum isn't low enough for an athlete, it won't be as noticeable. Only when the sebum is below 10% can better results be obtained.


As a "power" male hormone, Drostansterone Masteron is perfect for athletes looking for strength gains. It can greatly improve muscle strength, endurance and recovery speed without increasing muscle mass.


Drotandrosterone Masteron has little effect in the muscle-building steroid cycle. While it is possible to increase girth with high dose injections, there are too many other steroids that work better than this. Some people will inject drostansterone during the muscle-building phase to avoid fat growth, but this is actually not a good reason. Sebum should be controlled with diet and exercise. At the same time, although drotandrosterone Masteron has an anti-estrogenic effect, it is not strong enough to counteract the estrogenic reaction caused by a large amount of exogenous testosterone in the muscle-building cycle during the offseason and drugs such as Dianabol.



Side Effects:

In many ways, Drostansterone Masteron is a steroid with fewer side effects. Although there are some risks, it is well tolerated by most male users. We divide the side effects of Drostansterone Masteron into the following aspects to introduce.




Drostansterone Masteron does not aromatize nor does it carry any progestogenic properties, so side effects in this regard are unlikely to occur. This means that the symptoms of bitch milk and pussy will not appear. The high blood pressure caused by water storage will not appear either. This steroid does not need to be used in combination with an anti-estrogen. However, the effects of other steroids being used at the same time should also be considered in the mix-up plan.



androgen aspect:

Side effects of this include causing acne, accelerating hair loss, and promoting body hair growth. Although the androgenic effect of drotandrosterone, a derivative of dioxytestosterone, is relatively mild, this steroid can cause strong hair loss due to the different sensitivity of each person.


Note that Drostansterone Masteron will not be decomposed by 5-alpha decomposing enzymes. This enzyme works by breaking down testosterone into ketones. And Drostansterone Masteron is already a dioxytestosterone. This means that drugs such as finasteride cannot be used to suppress the androgen side effects of drotanosterone Masteron.



Drostansterone Masteron has a great effect on cholesterol levels in the body. While this effect is not as severe as that of many oral steroids, it still increases LDL cholesterol levels in the body while lowering HDL levels. Drostansterone Masteron also has a certain effect on blood pressure, but not very serious. Due to the negative impact on cholesterol levels, it is important to control cholesterol when using it. Do not use this medication if your cholesterol levels are already high. It's important to maintain a lifestyle with good cholesterol levels if your body is healthy enough to use them. That means eating a healthy diet, getting enough omega-3 fatty acids and avoiding saturated fats and simple sugars. Lots of cardio is also a must.



testosterone aspect:

Drostansterone Masteron will greatly inhibit the secretion of testosterone in the body, which makes the use of exogenous testosterone very important. Low testosterone levels can cause a host of side effects.


It is very important in fat loss cycles not to use too much exogenous testosterone as this can have a strong estrogenic effect.


When the drug is stopped and the extra hormones ingested are used up, the body will start producing testosterone itself again. The premise of this recovery is that your body's testosterone level is not too low, and HPTA is not damaged due to improper medication. Full recovery will take some time. Therefore most male users should have a course of treatment after a cycle is complete. This process includes the use of drugs such as tamoxifen Nolvadex, clomiphene, HCG chorionic gonadotropin is also useful. The combination of these three drugs will speed up your recovery process. Definitely can reach a level that will bring you back to health.

liver toxicity

Drostansterone is not hepatotoxic.



Use of drostansterone:

The standard dose for men is 300-400m per week. This means 100mg injected every other day for a period of 6-8 weeks. When using drostanolone enanthate, it can be injected 1-2 times a week, but this is not common.




The original drotasterone Masteron produced by Syntex has long been discontinued, and all the fakes are sold on the market. But genuine drotasterone is available on the black market. Alpha Pharma, Meditech Pharma are the most common. As for the use of drotasterone Masteron produced by other underground laboratories, there are certain risks. At the same time you will find that its price is relatively acceptable.




Drostanolone Propionate as an anabolic steroid does not have the effect of increasing muscle circumference, and it is also necessary to note that it can only be effective when the sebum is very low. You have to use drotasterone Masteron reasonably to get the desired effect. Of course if used properly Drostandrosterone Masteron can be a very valuable anabolic steroid during the fat loss phase.




There has always been great controversy about the dosage of drostansterone Masteron. The dosage level has always been a topic of debate among users. But what dosage is appropriate? In fact, the essence of this problem lies in whether you bought a good product or not. If it is high-quality Drostansterone Masteron, there is no need for a super high dose, but most people cannot find a more regular supplier. So be sure to buy genuine medicines.



Basic Dosage:

The basic dosage is about 200-300 mg per week. This is a very low dose and should be well tolerated by male users. People who take Trenbolone, Anavar, or Stanozol will find that low doses of Masteron do good. At the same time, its anti-estrogenic effect is enough to counteract most of the side effects.



Standard Dosage:

The standard dosage is about 300-400 mg per week or an average of 350 mg. 100 mg injected every other day. This dosage will greatly improve muscle hardness and dryness during the fat-loss steroid cycle. If it is not for muscle gain, a weekly dose of 300-400 mg can also have a good effect.



High doses:

This dosage means 200 mg per injection per day which is 600-800 mg per week. But this dosage can have a very bad effect on cholesterol levels. At the same time, it will produce strong androgenic side effects. Mastering this dosage requires a lot of experience and knowledge, and in many cases you don't have to.




For bodybuilders, the introduction of drotasterone Masteron at the end of a fat-loss steroid cycle results in a more refined muscle mass. On the basis of a guaranteed diet, drotasterone Masteron can make your muscles drier and harder. This is very important for bodybuilders preparing for competition. If you're looking to increase muscle size, this isn't the drug for you. But if you just want to change your shape a little bit and gain some growth, drotasterone Masteron may be an option. For some competitive athletes who do not need to increase muscle size, drotasterone Masteron can increase strength without increasing muscle under the premise of restricting calorie intake, and can also improve muscle endurance and recovery speed.
