Masteron (Drostanolone Propionate)

Masteron (also Drostanolone, Drolban, Metormon, Permastril, Mastager, etc.) is an anabolic steroid which originates from dihydrotestosterone. It has high androgenic and moderate anabolic properties. Masteron is not an aromatizable steroid (i.e. there is no conversion into estrogen), moreover it acts as aromatase inhibitor.

Therefore there is no risk of estrogen related side-effects, such as gynecomastia and water retention. In clinical practice it was used as a cure for breast cancer in women, however, due to the high risks of virilization, it is practically out of use today.

Due to its anti-estrogenic properties and slight diuretic effect Masteron became popular among bodybuilders. They take it to keep muscle mass and strength during cuting cycles.

Drostanolone is of special interest among those athletes who want to improve muscular endurance before competition without gaining of excessive bodyweight. Moreover it increases strength and has apparent fat burning effect. For example Drostanolone cycle can reduce the amount of body fat by 5-7%.

All above mentioned features of Masteron make it attractive for athletes of all types of sports. This substance is also useful during weight losing diet. Its application maintains the muscle mass and reduces catabolism.

Side Effects of Masteron

As we said above Drostanolone is not aromatizable, therefore gynecomastia, water retention and high blood pressure do not occur. Nevertheless androgenic side-effects are possible: aggression, acne, alopecia, prostate hypertrophy and virilization in women. One should also mention that Masteron has low liver toxicity.

Dosering en gebruik

The optimal dosage of Masteron is about 400-500mg/week. Higher doses do not produce further improvement of results, however the risk of side-effects may increase. As Drostanolone propionate has a short chain, you should take it three times a week (or EOD).

Combinaties

Owing to high affinity to androgen receptors, it makes good combinations with such steroids as :winstrol: or :anavar:. They have less interaction with androgen receptors, therefore this stacking may produce synergistic effect during cutting cycle.

For a bulking cycle you can combine it with :testosterone-p:. However this combination suppresses natural testosterone production, so :gonadotropin: usage is required. Also bodybuilders combine Masteron with :trenbolone: or :boldenone:.
