Mastorox, also known as Drostanolone Propionate, is an injectable anabolic androgenic steroid (AAS) widely used in bodybuilding and athletics. Known for its ability to enhance muscle hardness and density, Mastorox is a favorite among those looking to improve their physical appearance and performance. This guide provides comprehensive information about Mastorox, covering its indications, contraindications, administration, medical action, precautions, side effects, overdosage, and conclusion.


Mastorox is primarily indicated for use in the treatment of breast cancer in women. It works by inhibiting the growth of estrogen-dependent tumors. In the realm of bodybuilding and athletics, Mastorox is used for its anabolic properties, which help in muscle building, increasing strength, and enhancing overall physical performance. Athletes and bodybuilders often use it during cutting cycles to maintain muscle mass while reducing body fat.


Mastorox should not be used by individuals with the following conditions:

  • Prostate cancer
  • Breast cancer in men
  • Severe liver or kidney disease
  • Known hypersensitivity to Drostanolone or any of its components
  • Pregnancy or breastfeeding

Women who are pregnant or may become pregnant should avoid Mastorox due to the potential for causing harm to the fetus. Individuals with pre-existing heart conditions or a history of cardiovascular issues should also avoid using Mastorox due to the risk of exacerbating these conditions.


Mastorox is administered via intramuscular injection. The typical dosage for bodybuilders and athletes ranges from 200 to 400 milligrams per week, divided into two or three injections. The exact dosage may vary based on individual goals, experience with steroids, and response to the drug.

The injection site should be rotated to prevent local irritation and muscle damage. The cycle duration for Mastorox typically lasts between 6 to 12 weeks. It is often stacked with other anabolic steroids, such as Testosterone Propionate or Trenbolone, to enhance results. Post-cycle therapy (PCT) is recommended after discontinuing Mastorox to help restore the body’s natural hormone levels.

Medical Action

Mastorox is a derivative of dihydrotestosterone (DHT), which means it does not convert to estrogen and thus avoids estrogen-related side effects such as water retention and gynecomastia. It has a high anabolic rating, making it effective at promoting muscle growth and strength without significant androgenic effects.

Mastorox works by binding to androgen receptors in muscle tissues, promoting protein synthesis and nitrogen retention. This leads to an increase in muscle mass and strength. Additionally, Mastorox can enhance fat loss by increasing the body’s metabolic rate and promoting a leaner, more defined physique.


While using Mastorox, certain precautions should be taken:

  • Regular blood tests to monitor liver and kidney function
  • Monitoring of blood pressure and cholesterol levels
  • Avoiding use in individuals with a history of cardiovascular disease
  • Being aware of potential masculinizing effects in women
  • Not exceeding recommended dosages to minimize side effects

Athletes should also be cautious of drug-testing regulations in their sport, as Drostanolone can be detected in the body for several months after the last injection.

Side Effects

Like any anabolic steroid, Mastorox can cause side effects. Some common side effects include:

  • Acne and oily skin
  • Hair loss in those predisposed to male pattern baldness
  • Increased body hair growth
  • Voice deepening in women
  • Changes in libido

More serious side effects can include:

  • Liver toxicity
  • Increased risk of cardiovascular disease
  • High blood pressure
  • Elevated cholesterol levels
  • Suppression of natural testosterone production

Prolonged use of Mastorox can lead to more severe health issues, including liver damage and increased risk of heart attack or stroke. Users should be aware of these risks and monitor their health regularly.


Overdosage of Mastorox can exacerbate the side effects mentioned above. It may lead to severe cardiovascular issues, liver damage, or hormonal imbalances. If an overdose is suspected, it is crucial to seek medical attention immediately. Treatment for overdose typically involves discontinuing the drug and managing symptoms through supportive care.


Mastorox, or Drostanolone Propionate, is a powerful anabolic steroid used to enhance muscle mass and performance. While it is effective for these purposes, it is essential to use it responsibly and under medical supervision to minimize potential side effects. Regular monitoring and adherence to recommended dosages can help mitigate risks. As with any anabolic steroid, it is important to weigh the benefits against the potential health risks and to consider alternative methods for achieving fitness goals.

In summary, Mastorox is a versatile steroid that offers significant benefits for those looking to improve muscle density, strength, and overall physical appearance. However, it is not without its risks, and responsible use is crucial to ensure safety and effectiveness. Whether you are a seasoned athlete or a bodybuilder looking to enhance your performance, understanding the proper use and potential risks of Mastorox can help you make informed decisions and achieve your fitness goals safely.
