Benefits of Dosy-Tax Injection

Prostate cancer
Prostate gland is a small walnut-sized gland that produces a fluid called seminal fluid that nourishes and transports sperms in males. The most common symptom of prostate cancer is difficulty with urination, but sometimes there are no symptoms at all. Dosy-Tax 20 RTU Injection decreases or stops the growth of cancer cells by decreasing the amount of testosterone (natural hormone in males) in men. This also relieves difficulty in passing urine and makes it easier for you to urinate.
