Muscle Gain Powder Bulking Cycles Steroids Masteron Drostanolone Propionate

Also known as: Masteron, Drostanolone, Dromostanolone, Drostanolone Propionate, Drostanolone Enanthate


Pharma brand names: Drolban


There are two different variants of Masteron:

Drostanolone Propionate

Drostanolone Enanthate


Iochemistry of Masteron / Drostanolone


It is believed that if the enzyme 3-hydroxysteroid dehydrogenase was neutralized, DHT would actually be a very powerful anabolic steroid. Drostanolone's methyl group addition makes it imune to this enzyme.

Masteron is a modified form of Dihydrotestosterone, with a methyl group at the 2nd carbon (carbon alpha) atom. This modification is responsible for the anabolic strength increase. This methyl group makes it harder for the enzyme 3-hydroxysteroid dehydrogenase to metabolize Masteron. This enzyme is abundantly present in muscle tissue, and is responsible for degrading any DHT into two inactive metabolites: 3-Alpha Androstanediol and 3-Beta Androstanediol. Because of this enzyme DHT is not anabolic in muscle tissue at all.


Drostanolone is injected into the body as an ester (bonded to either Propionate or Enanthate). Enzymes cleave off the ester from the Masteron molecule - which takes varying amount of time depending on which ester was used. This process causes the gradual release rate and extended half-life of the steroid. Drostanolone Propionate has a half-life of 2.5 days, while Drostanolone Enanthate has a half-life of 10 days.


Intended use of Drostanolone / Masteron


Masteron was initially marketed as a treatment of female breast cancer. Because it pronounced male characteristics in women and because more effective breast cancer treatments were invented, Drostanolone was gradually phased out.


Actual use of Masteron


Nowadays Drostanolone is a very popular anabolic steroid used mainly by athletes and bodybuilders.


How to use Masteron?


Where to inject Drostanolone / Masteron


Like other steroids Masteron can be injected into any muscle (if the muscle is big enough). The most popular being buttocks, shoulders and triceps.


Masteron cycle compatibility, examples and duration


Like majority of steroids, Masteron acts very well in combination with Human Growth Hormone (4IU per day).


Effects of Drostanolone / Masteron (desirable)


There are principally two desirable effects of Testosterone:

physical / athletic performance enhancement (endurance, strength, faster regeneration)

physique enhancement (muscle buildup, fat loss)

The rest of desirable testosterone effects that an individual might experience during the steroid cycle, include:

increase in collagen synthesis and bone mineral content. Collagen is the protein-based construction material for connective tissues throughout the body (the ligaments, tendons, cartilage, joints, and bones).

heightened self esteem

deeper (manly) voice

darkening and thickening of body hair

increase in levels of IGF-1 and MGF hormones (which also promote muscle growth)

increased hemoglobin (red blood cell count)

anti-catabolic effect on muscle tissues by way of acting as an anti-glucocorticoid
