Drostanolone is an anabolic steroid that was produced in the 1970’s under the trade name Masteron by Syntex pharmaceuticals. The original use for Masteron was to treat breast cancer, however over the years more effective treatments have become available. Masteron is part of the DHT (Dihydrotestosterone) derived steroid family and as with other steroids in this family, this steroid does not aromatize (convert to estrogen).
Masteron is not a strong anabolic steroid and does not promote large strength or muscle gains. It is however extremely popular for cutting cycles, especially for bodybuilders preparing for a competition. Drostanolone is known for its ability to give muscles a dry and shredded appearance.
Masteron as an Anti Estrogen
Masteron is one of the only steroids to contain strong anti estrogenic properties. Often when bodybuilders use Masteron in a cycle, there is no need to incorporate drugs such as Nolvadex or Letrozole. This however would depend on what other steroids are being used and how sensitive the bodybuilder is to estrogen. Masteron is unlikely to prevent estrogen related side effects when large amounts of steroids that aromatize are being used.
Masteron Side Effects
When being compared to other anabolic steroids, Masteron is considered to be quite mild in terms of side effects. One of the main benefits of Drostanolone being a DHT derived steroid, is that there are zero estrogen related side effects when using this steroid. Thus, side effects such as water retention, gynecomastia and bloating will not be a problem when using this steroid. Although Masteron is a mild steroid, there are still possible side effects.
Some side effects associate with Masteron include:
- Oily skin which can lead to acne
- Male pattern baldness
- Increased hair growth
- Negative effect on cholesterol
- HPTA shutdown
Dosage and Cycles
Due to the effects Masteron has on the body, it would make no sense to use Masteron in a bulking cycle. Masteron is often used in a pre-contest cycle, where the bodybuilder is looking to achieve that “dry and shredded” look. Masteron is typically used for 8 to 10 weeks at a dosage between 200 and 400mg a week. It is often combined with other popular cutting steroids such as Testosterone Propionate, Trenbolone Acetate, Anavar and Winstrol.
