Masteron Propionate

Masteron is a derivative of dihydrotestosterone or DHT which restrains the conversion to estrogen through aromatization. It could be that its ability to inhibit estrogen from interacting with the aromatase enzyme or it blocks the receptor that binds the estrogen that causes this phenomena. Whatever the reason, because of its anti-estrogenic properties it blocks the conversion of free testosterones to estrogen through aromatization. This makes Masteron a common inclusion in a high anabolic cycle. Drostanolone Propionate is a dihydrotestosterone (DHT) derived anabolic steroid. Specifically, Masteron is the DHT hormone that has been structurally altered by the addition of a methyl group at the carbon 2 position, This protects the hormone from the metabolic breakdown by the 3hydroxysteroid dehydrogenase enzyme, which is found in the skeletal muscle.

Product Function:

It is used primarily by athletes who need to retain strength while losing mass. It is beneficial to runners and athletes who must remain in a certain weight class.

It can increase muscle hardness and density, giving an individual a more complete appearance when competing on stage.

It can promote increased strength while keeping body fat the same or even lowering it, something can help to prevent muscle loss while dieting .

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.

Masteron Stacks

Masteron can be used as the sole injectable: in this case, I prefer to see dosing of 500-700 mg/week. A Masteron/Dianabol stack is more effective however, as is a Masteron/Anadrol stack. Testosterone also combines well with Masteron.

Another use of Masteron which has become more common lately is combination with trenbolone. Unlike combination with Dianabol or Anadrol, there is only an additive effect, not a synergistic effect. However, including Masteron allows a lower trenbolone dosage while achieving very similar or equal physique benefit with less potential for trenbolone-specific side effects of night-sweats, increased tendency to aggression, and/or insomnia.

Masteron also is useful in combination with testosterone for self-prescribed hormone-replacement therapy (HRT.) For example, 100 mg/week each of Masteron and testosterone can be superior for physique benefits to 200 mg/week testosterone alone, while being milder in side effects due to lower resulting levels of estradiol (estrogen) and DHT
