Masteron propionate, also known as drostanolone propionate is a moderate anabolic/potent androgen which does not aromatize to estrogen. Water retention and gynecomastia are therefore not a concern with this compound. Masteron may in fact exhibit antiestrogenic 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 manner as the oral steroid Proviron.
The general dosage for masteron propionate is anywhere between 100 to 200 mg every 2 or 3 days in order to maintain a consistent level of hormone in the blood.
How to use:
Masteron is usually used on combination with other injectables such as Testosterone, Deca, Trenbolone, etc. For greater mass gains, one can alternately addition a stronger androgen such as Dianabol or an injectable testosterone. The result here can be an extreme muscle gain, with a lower level of water retention & other estrogenic side effects than if these steroids were used alone (usually in higher doses). 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.
