Masteron (drostanolone propionate) after a long period of time as a rare drug is now enjoying greater popularity, and deservedly so.
Where one does not wish to use a large amount of injectable testosterone and wishes to use either no trenbolone or only a modest amount of that drug, Masteron is often an ideal choice for inclusion in a steroid stack, or in some cases for use as the sole injectable for a steroid cycle.
Masteron Side Effects
Masteron undergoes no aromatization (conversion to estrogen), no conversion to DHT or potentiation by the 5-AR enzyme, and as an unalkylated steroid it poses no liver issues. In these regards and also in overall side effects, Masteron is best compared with Primobolan Depot.
In terms of positive effects in an anabolic steroid cycle, Masteron is at least as effective as Primobolan per milligram for mass gain and for fat loss, and appears better for hardening.
Masteron as an Anti-Estrogen
Dromostanolone has some reputation for anti-estrogenic activity, but in actuality this effect is fairly subtle. If due to use of aromatizing steroids a steroid cycle would produce substantially excessive levels of estrogen, adding Masteron to the cycle will not fix that. Instead, an anti-aromatase such as letrozole or anastrozole should be used. However, where only a moderate amount of aromatizing steroid is being used, Masteron can in many instances be sufficient as the sole anti-estrogenic agent.
