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.

How Masteron Compares to Other Steroids

Many have called Masteron a “weak” steroid, but this definitely is not the case. What often has been weak has been the doses! Doses of this drug have historically been low because of rarity, price, and low concentration of the preparations (100 mg/mL.) However, both availability and price have improved markedly in recent years.

When included as part of a steroid stack, Masteron’s contribution per milligram is at least as great as that of testosterone, boldenone (Equipoise), nandrolone (Deca), or methenolone (Primobolan.) But of course, if only 100 or 200 mg is added per week, there will be no large change seen from such a small addition.
