Masteron is DHT (dihydrotestosterone) derivative. It is an injectable anabolic steroid. It is generally available as ? Drostanolone Propionate and Drostanolone Enanthate. It is commonly slanged as Mastabol, Mast, or Masto. Its chemical structure is 2a-methyl-androstan-3-one-17b-ol. The Propionate version of Masteron is known as Masteron Propionate, and the Enanthate version is known as Masteron Enanthate.

Masteron Propionate (Drostanolone Propionate) is an androgenic / anabolic steroids (AAS) that was originally developed as an anti-estrogen for treating breast cancer, and it was extensively used with the SERM (Selective Estrogen Receptor Modulator) Tamoxifen (Nolvadex) for the purpose.

Masteron Propionate and Masteron Enanthate are both anabolic steroids, but the main difference between the two is that Masteron Propionate is fast acting anabolic steroid. It is usually dosed at 50-150mg/ml. On the other hand, Masteron Enanthate is the slower, but longer acting anabolic steroids. Masteron Enanthate contains ester attached to the drostanolone that is responsible for slower, but longer release of hormone. Where Masteron Propionate is needed to be injected every other day, Masteron Enanthate just requires to be injected twice per week. Masteron Enanthate is generally dosed at 200mg/ml.

Often used by athletes, Masteron helps their blood levels to rise and also helps to shoot up their plasma levels. Masteron Enanthate is one of the favorite injectable anabolic steroids of bodybuilders and athletes, because it has anti-estrogenic properties due to which it does not convert to estrogen through aromatization, and it works for longer durations.

Masteron is effective in blocking the conversion of free testosterone into estrogen by using the aromatization method which helps in increasing the amount of free testosterone, and thus prevents any side effects to occur which would have occurred if it would have converted into estrogen.

However, the use of Masteron Propionate and Masteron Enanthate has been linked with several side effects, such as gynecomastia, water retention and dangerous increases in blood pressure, hair loss, aggression, and acne. It may also result in loss of libido as it shutdown's the production of testosterone in body.

On the whole, Masteron Enanthate/ Propionate are weak anabolic steroids, and thus not much in independent use. It is often recommended for stacking with other steroids. Masterone is a safer that other anabolic steroids, as the possible side effects of Masteron Enanthate/ Propionate are not so deadly. However, it is not recommended for the beginner steroid users.
