With regular use as advised by a doctor, it can help maintain mobility, reduce bone pain, and improve quality of life.
Treatment of Breast cancer
Decasier 25 Injection is used as part of supportive care in advanced breast cancer. It can help improve strength, maintain muscle mass, and support overall health, especially in patients experiencing weight loss or fatigue. Its use is determined by the doctor based on the individual’s condition and treatment goals.

How Decasier Injection works

Decasier 25 Injection is an anabolic steroid that works by promoting the growth and repair of body tissues. It improves protein synthesis and increases calcium retention in bones, which helps strengthen bone density in postmenopausal osteoporosis. It also stimulates the production of red blood cells in the bone marrow, making it effective in treating certain types of anemia. In breast cancer, Decasier 25 Injection may help improve strength, support weight maintenance, and counteract muscle loss, particularly in advanced stages where patients experience fatigue and physical decline.
