Testosterone replacement therapy (TRT) in a med spa is a treatment used to increase testosterone levels in men with low testosterone levels. Testosterone is an essential hormone for the development and maintenance of muscle mass, libido and sexual function in men. When testosterone levels decrease with age, symptoms such as fatigue, decreased sexual desire, decreased muscle mass and increased body fat can occur. TRT is administered under medical supervision and can be given in the form of pills, patches, gels, creams, or injections. In a med spa, TRT can be combined with other treatments to improve health and well-being, such as nutrition, exercise and ozone therapy. It is important to note that every person is different and it is necessary to speak with a specialist before starting any treatment.
