Testosterone is one of the most important male hormones that plays a crucial role in growth and development of secondary sexual male characteristics. It is the hormone that is mainly important for the development of primary sex characteristics in males. It is produced chiefly by the testes and it is produced in smaller quantities by the adrenal glands, and its production reaches to a peak level when boys reach adolescence age and even in their twenties.

Testosterone plays an important role even during prenatal development in all human beings. It indicates the gender of the developing embryo. It is responsible for the growth of sex organs and the prostate gland and even has an adverse effect on the brain development as this hormone is responsible for the brain masculinization in infant boys. In the childhood stage, testosterone is associated with the appearance of pubic hair, axillary hair, and hair on the upper lips. During adolescence, boys acquire a voice change with deeper pitch, even their facial features take on a more defined contour, muscle bulk increases, shoulders become broader, and the skin turns oily because of enlargement of sebaceous glands, all thanks to a surge in testosterone production.

Testosterone also plays vital role in bone mineral density. Bone density decreases if testosterone levels drop. This leads to the risk of weak bones. So you can use this steroid for bone strength which can boost athletic performance.

Since testosterone helps in development of primary sex characteristics in males, as boys reach their adulthood age, the role of this testosterone takes on more importance as it regulates normal sperm development. So, normal level of testosterone is required in men to maintain an active sexual desire. This testosterone drug helps men to lose extra pounds by increasing energy metabolism to maintain a fit and strong physique. Testosterone deficiency in men generally leads to loss of energy and also leads to poor sexual performance. Testosterone product must not be used by the persons who have breast cancer and prostate cancer.

But anyhow, it is better to consult your doctor about your overall prostate health before starting testosterone therapy. It is strongly recommended to consult your doctor if you experience symptoms like vomiting, jaundice, swelling in your feet or at ankles or in hands, severe urinary problems, rashes and hives, difficulty in breathing especially at night and even in cases of frequent erections.
