Masteron 100 (100 mg/mL)


Brand: Dragon Pharma
Active Substance: Drostanolone propionate (Masteron)
Package: 10 mL vial (100 mg/mL)



Masteron is an anabolic steroid which is accessible as esters Propionate and Enanthate, although the most popular ester of the two is Drostanolone Propionate, which is the active ingredient of this product by Dragon Pharma. Drostanolone is comparable in organic activity of dihydrotestosterone, as it is a subordinate of this hormone. Masteron has weak androgenic activity and a moderate anabolic effect. Masteron doesn’t aromatize in the body (therefore it isn’t changed into estrogen), on the contrary, it is an aromatase inhibitor. Drostanolone Propionate is generally utilized by competitors in bodybuilding.

Properties of the drug

Anyone who uses Masteron will receive high quality mass gains without the addition of excess water. Therefore, Masteron is an anabolic steroid preferred by most bodybuilders and athletes as a drying agent. It allows you to achieve the contouring of each muscle with a minimum content of fat in the body.

Masteron has been shown to be a mild aromatase inhibitor as well as blocking estrogen at receptors in breast tissue. This is the reason for the original and primary use of Masteron as an advanced drug for the treatment of breast cancer.

Masteron works to inhibit the aromatase enzyme, thereby eliminating the ability of estrogen to form from aromatized anabolic steroids during the aromatization process. In fact, it effectively reduces any water retention as estrogen levels continue to decline due to an increase in the number of disabled aromatase enzymes.

Dosage and cycles of Masteron

The length of Masteron cycles is between 10-12 weeks. This is primarily because of its short ester nature. It is normal for bodybuilders to use Masteron in the last 2 months of a cycle before a competition or even photoshoot.

The recommended dosage of Masteron is between 200mg and 500mg per week with injections done every other day.

To build muscle mass, Masteron is combined with Testosterone Propionate. In such a cycle, it is also advised to use gonadotropin. This allows you to make up for the degree of endogenous testosterone. The best similarity of Drostanolone is shown in related drugs, for example, Trenbolone and Boldenone, which can also be combined in a cycle with Masteron.

Common Side Effects of Masteron

Masteron is viewed as a steroid that is genuinely gentle with regards to negative reactions. However, it is essential to note that there is always the chance of symptoms when anabolic steroids are present within the body. The following negative reactions are possible:

  • Faster hair loss.
  • Increased aggression.
  • Virilization (Male characteristics development in women).
  • Prostatic hypertrophy.


Masteron is regarded by the bodybuilding community as one of the “mild” anabolic steroids when it comes to side effects. In addition to this, the gains from the use of Masteron are more often than not of the highest quality in terms of definition and firmness.
