Drostanolone Enanthate is an injectable steroid which contains the hormone Drostanolone Enanthate. Drostanolone Enanthate, is a long estered variant of Drostanolone.
Masteron, as it is often called, is most commonly used by bodybuilders who are in the cutting phase of their training and dieting. While only mildly anabolic, this steroid extremely androgenic and because of this, brings about a very pronounced amount of hardness and definition to the muscles. On top of this, Drostanolone Propionate is also noted as being an effective estrogen blocker, and also binds to SHBG, making it possible for other steroids being used to bind more easily to their respective receptors, thus making their presence in the body much more effective. These effects are also noted by bodybuilders who choose to use the oral preparation of Masteron, Proviron.
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.
Common androgenic side effects are possible with Masteron, such as oily skin and increased libido. Due to its extremely androgenic properties, this drug is not a favorite among women bodybuilders, although most serious competitors still choose to use it due to its effectiveness as a pre-contest drug. Enanthate ester version having a half-life of probably 5 days has become available. This version of Masteron may be injected as infrequently as twice per week.
