Proviron, also known as Mesterolone, is a DHT-based oral steroid that has been used for many years in the field of bodybuilding and performance enhancement. It is known for its ability to bind to sex hormone-binding globulin (SHBG), which allows for increased circulation of free testosterone in the body. This can be beneficial for those looking to boost their training regimen. While Proviron is not typically used for building large amounts of muscle mass, it is often used during cutting cycles to help increase muscle hardness and density. Additionally, it is commonly used in modern medicine as a therapeutic agent for various conditions.
