Testosterone

Testosterone is generally thought of as a male hormone, but women make it too. Without it, they have no motivation, energy, ability to build lean muscle mass, or libido. Men who lack testosterone feel generally fatigued, moody, become overweight . Lack of testosterone is also linked with impaired glucose metabolism (type 2 diabetes) and high cholesterol. It interferes with libido, but is not usually the primary cause of erectile dysfunction. The organ with the most testosterone receptors (the most sensitivity to testosterone) is the heart. Testosterone is not well-absorbed when taken by mouth, which is why it Is applied topically (to the skin), injected in a muscle, or inserted subcutaneously (under the skin) in the form of pellets.
