Drostanolone Propionate is an anabolic androgenic steroid that first hit the market around 1970 under the trade name Masteron manufactured by Syntex.

Mastabol (Drostanolone) carries relatively normal anabolic and androgenic ratings; however, these ratings are something missing. It’s important to remember DHT, the basis of Drostanolone, is five times more androgenic than testosterone with a much stronger binding affinity to the androgen receptor. This again promotes a harder look and can also enhance fat loss.

Drostanolone Propionate is the propionate salt form of dromostanolone, a synthetic anabolic steroid related to dihydrotestosterone that has antiestrogenic effects. Dromostanolone inhibits the growth of estrogen receptor-presenting breast cancers; its virilizing effects limit its clinical usefulness. It would also become popular cutting steroid among bodybuilders, which is where Drostonolone is currently most commonly found.


Mastabol (Drostanolone is a 2-methylated dihydrotestosterone (DHT) which makes it very similar to its more popular sibling, Proviron. Basically, all the DHT derivatives are strongly androgenic, with limited anabolic and non-existent estrogenic effects. They also show strong affinity for enzyme aromatase (it facilitates conversion of some steroids to estrogens) without actually aromatizing. This specific feature makes them good candidates for use as anti-estrogens, but it must be noted that Proviron is better suited for this role.
Drostanolone propionate is therefore used in bodybuilding solely as an androgenic steroid during the cutting cycle. Although often stacked with other anabolic steroids, it serves this purpose very well on its own: Masteron helps to shed fat and helps to keep the muscle mass while causing no water-retention.


The drug has the property to assure positive nitrogen balance in humans and promotes protein synthesis. It has the goal to offer increased strength while keeping body weight and lose body fat.

  • Improves endurance

  • Average increases in strength

  • Faster regeneration

  • Burn 5-7% of fat during cycle

  • No water retention

  • Muscle build-up

  • Increases in collagen synthesis and bone mineral content.

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

  • Increases haemoglobin (red blood cell count)

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

Without question, the effects of Masteron will be displayed in the most efficient way during a cutting cycle.
