1. Product description:
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.
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.
Provided everything fits as if should, the user can achieve that "ripped" look so popular to professional bodybuilding. The androgenic effect can also be crucial during this period, a time when caloric intake is drastically lowered. The user is provided added "kick" or "drive" to push through the grueling training sessions leading up to the show.
Masteron could of course be used during cutting phases of training as well. A cycle of this drug combined with Winstrol, Primobolan or Oxandrolone should provide great muscle retention and fat loss, during a period which can be very catabolic without steroids. It is an added benefit that none of these steroids aromatize, and therefore there is no additional worry of unwanted water and fat retention.
