Oxandrolone, also known as Anavar, is a synthetic anabolic steroid that mimics the effects of testosterone. It is commonly used to help regain weight lost after surgery, chronic infections, or severe trauma. It is also effective in reducing bone pain caused by osteoporosis. Due to its mild androgenic properties, Oxandrolone is favored among bodybuilders and athletes for muscle retention during cutting cycles. It also shows minimal side effects compared to other anabolic steroids.
