Estrogen, which is the main enemy of breast cancer patients, is curbed through SERM and AI. Master also shares these characteristics and is capable of preventing estrogen buildup in the body. As DHT derivative, it does not allow aromatization and displays strong anti-aromatase properties. For this reason, Masteron has been used in combination with other drugs to treat breast cancer patients. The role of Masteron then was to block the amount of estrogens in the body while other drugs, such as Tamoxifen-citrate were used to block the binding of estrogen at the breast receptors. Today, many other more powerful aromatase inhibitors have replaced this breast cancer treatment to achieve even greater success in the fight against breast cancer.
A total anabolic steroid cycle can last anywhere from 8-16 weeks most commonly, and in some cases, especially in hardcore circles even longer. As for the Trenbolone Enanthate cycle, 8-10 weeks is about all you'll want if your health is to be maintained. For off-season periods of use, the compound can be added in at any time, the frontend or backend of an off-season plan is fine. For some, switching back and forth between Trenbolone and Nandrolone compounds can be a great way to go. For the cutting phase, this is where a Trenbolone Enanthate cycle will almost always be best served at the backend of a plan. You will get more out of this steroid once you're already somewhat lean when it's being used for cutting purposes.
