Overview and History of Masteron

Masteron is the trade name for the anabolic steroid Drostanolone. Materon is an injectable oil-based anabolic steroid and is derived from dihydrotestosterone (DHT), which makes Masteron a member of the DHT-derived family of anabolic steroid derivatives and analogs. Essentially, all anabolic steroid analogs and derivatives are modifications in one way or another of the three primary anabolic steroids naturally found in all humans: Testosterone, Dihydrotestosterone, and Nandrolone. In this case, Masteron’s progenitor (or parent) hormone is Dihydrotestosterone. Other anabolic steroids that belong in this family of DHT derivatives include Anavar, Winstrol, Anadrol, Primobolan, and various others. Masteron is not regarded as a very strong anabolic steroid, nor is it a weak one. Its anabolic strength is generally regarded as moderate at best (anabolic rating of 62–130), while its androgenic strength is fairly low (25–40).

Masteron Cycles and Uses

Masteron cycles tend to be quite limited in their dynamics and applications. This is because the nature of the compound is unfavorable for bulking, strength gain, and the like. Unfortunately, as a cutting-edge or fat-loss agent, there are much better anabolic steroids at the disposal of the individual than Masteron. Therefore, the only particular Masteron cycles that bodybuilders tend to use involve pre-contest and cutting/fat-loss cycles. Even in cutting or fat loss cycles, Masteron is usually not a key-role compound involved.

The cycle length of Masteron cycles is usually in the range of 8–10 weeks, mostly due to their short nature. Some bodybuilders will elect to utilize Masteron only within the final 2–4 weeks of a cycle leading up to a show or a photoshoot, only to gain advantage of its physique enhancement abilities. This generally looks like a cycle performed for 10 weeks, with compounds such as Testosterone Propionate, Trenbolone Acetate, and Anavar being used. Towards the 6 or 8-week mark of said cycle, Masteron would be included in the mix (along with perhaps a removal of one of the other compounds) and run right to the end of the 10^th week.

Masteron Side Effects

Masteron is regarded by the bodybuilding community as being one of the mild anabolic steroids when it comes to side effects. This is due in large part to the fact that Masteron is a DHT derivative. Having been derived from DHT, it therefore possesses all of the same (or similar) attributes and features that DHT does. This includes the inability to interact with the aromatase enzyme and, therefore, being completely void of any estrogen-related side effects.

As previously mentioned, Masteron is void of any estrogenic side effects because it is a DHT derivative. Not only does it completely avoid aromatization (conversion into estrogen), but evidence suggests that it behaves as a mild aromatase inhibitor as well. Side effects resulting from Estrogen buildup (such as water retention, bloating, fat retention and gain, and the development of gynecomastia) are completely avoided or reduced with the use of Masteron.

Masteron Dosages and Administration

For athletic and bodybuilding purposes for male users, Masteron dosages are in the range of 200–400 mg per week, and the lower end of this range (200mg) is commonly utilized for pre-contest preparation and cycles. Because Masteron is specialized as an aesthetic physique-enhancing compound, intermediate and even advanced users tend not to venture higher than the 400 mg/week mark. It must be remembered that Masteron is a weak compound where the addition of strength, mass, and muscle is concerned, and there are more effective (and cheaper) compounds for this purpose.
