Testosterone is the main male hormone responsible for normal growth and development of the sex organs, in addition to body mass, bone structure and general mood. In men it is produced in the testes. It is controlled by the pituitary gland and hypothalamus.
Treatment for individuals with low levels of testosterone. Treatments can be in the form of injections, gels, creams, patches or pellets. Alternatively, you can take Tesosterone Boosters like Centrapeak that will supplement and boost your Testosterone levels
Signs include: weight gain, loss in strength, reduced sex drive, erectile dysfunction, emotional changes (depression, mood swings etc), and irregular sleep patterns.

In males, hypogonadism is the diminished activity of the gonads: a decrease in either testosterone or sperm production, or both.
Side-effects may include: disruption in sleeping, increase in the amount of red blood cells (may lead to blood clots or heart attacks), oily skin, and fluid retention.
TRT is generally not recommended if you suffer from prostate / breast cancer or incurable severe sleeping disorders. If in doubt of anything relating to TRT (or any treatments or medication), consult your doctor or physician.
