1.  Drostanolone propionate (trade name Masteron) is an anabolic/androgenic steroid which is the


propionate ester of drostanolone. It is known to be androgenic and anabolic. It is incapable of


aromatization and has similar properties to dihydrotestosterone. It has been successfully used as a breast


cancer drug, but because of the high risk of virilization, safer options are prescribed. Drostanolone


propionate is used primarily by athletes who need to retain strength while losing mass. It is beneficial to


runners and athletes who must remain in a certain weight class.


2.  Masteron is an injectable preparation containing the steroid drostanolone propionate. Drostanolone is


a derivative of dihydrotestosterone, most specifically 2alpha-methyldihydrotestosterone. As a result, the


structure of this steroid is that of a moderate anabolic/potent androgen which does not aromatize to


estrogen. Water retention and gynecomastia therefore do not come into play with this drug. Masteron may


in fact exhibit anti-estrogenic activity in the body, competing with other substrates for binding to


aromatase. This would reduce the conversion rate of other steroids, Masteron acting in the same way as


the oral steroid Proviron.


3.  Bodybuilders have a strong like for non-aromatizing androgens, and find Masteron very useful in a


cutting phase. It is generally used for a number of weeks prior to a competition, in an effort to bring out an


improved look of density and hardness to the muscles. As long as body fat percentage is low enough,


Masteron should work very well.

1.  Since the propionate ester is used with this compound, injections need to be repeated at least every 3


or 4 days in order to maintain a consistent level of hormone in the blood. The weekly dosage is in the


range of 300-500mg.


2.  Since estrogen is not an issue, side effects are generally mild with this steroid. As discussed earlier,


gynecomastia, water retention, and high blood pressureare not a problem. Masteron is also not liver toxic,


so there is little concern stress will be placed on this organ, even during longer cycles.The only real side


effects would be from the basic androgenic properties of dihydrotestosterone. These  i ncludes oily skin,


acne, body/facial hair growth, aggression and accelerated hair loss.


3.  Since this compound is already a synthetic DHT, Proscar would have no impact on the level of


androgenic effects. Men with a receding hairline or those with a predisposition for baldness may therefore


wish to stay away from Masteron completely, as the potent androgenic effect of this steroid can easily


accelerate this condition.
