Manufacturer: Alpha Pharma
Substance: Drostanolone Propionate
Package: 10 ampoules (100 mg/ml)


Mastebolin is a sports pharmacology drug that is characterized by moderate androgenic and anabolic effects. It produced by the well-known manufacturer Alpha Pharma and contains the active substance Drostanolone Propionate (known as Masteron to sports personnel). This injectable steroid is used by athletes in high-quality muscle mass gaining cycles without any side effects.


The effectiveness of steroid

Athletes choose this drug because, with its help, it is possible to achieve the following results during a cycle:

  • Promoting faster growth of high quality muscle mass;
  • Stimulating the processes of breaking down fat cells;
  • Increased strength;
  • Increased endurance.

Also, the steroid helps to normalize the catabolic processes occurring in the body with a moderate diuretic effect. After the end of the intake, the athlete receives a beautiful, defined muscle mass with rather sharp outlines. Some athletes claim that the drug is able to highlight strengths and mask weaknesses. With it, you can train in extreme conditions without fear of losing weight. In the period of preparation for a sports competition, this drug has no equal.  

How to take it correctly?

To achieve their goals without compromising health, an athlete needs to take Masteron in a weekly dosage of 200-500mg. Amateurs and novice athletes should start with the lowest dose. The usual cycle duration can be from 6 to 10 weeks. An independent decision regarding exceeding the dosage and duration of administration can cause health problems. In addition to solo use, experienced athletes can use the steroid in combination with other drugs in sports pharmacology. This will minimize the likelihood of side effects, and will allow you to get the most out of the cycle. Most often, the steroid is combined with Testosterone Propionate, Winstrol or Oxandrolone.  

Side effects

Potential side effects from the use of Masteron include: increased skin oiliness (as a result of increased production / secretion of sebum), increased growth of facial hair and body hair, and an increased risk of triggering MPB (male pattern baldness) in those that are genetically sensitive or predisposed to it. Virilization (development of masculine characteristics in women) also poses a risk of use by women, although its use in women with breast cancer should indicate its acceptable nature as a female component. It may also have negative effects on cholesterol as the ability of Masteron to lower serum estrogen levels leads to a measurable decrease in HDL cholesterol (good) and increases LDL cholesterol (bad). Masteron does not have hepatotoxicity (liver toxicity), but like any anabolic steroid, it helps suppress or even stop HPTA, thereby decreasing endogenous testosterone production. In the Masteron injection section you can see products from other manufacturers. We also recommend that you familiarize yourself with the full section of Injectable Steroids. Delivery of Masteron to the USA is carried out within 5-12 business days. If you have any questions, feel free to contact our customer service team for advice.

    Ever since I first used Masteron I have loved this compound! It makes me feel amazing and the results aren’t too bad either! Now I know it can be a little pricey but for how great I feel when using it, it is worth every cent!
