TRT stands for testosterone replacement therapy, which is a medical treatment used to help people with low testosterone levels. It is primarily used to treat low testosterone levels that can occur with age or as a result of a medical condition. However, it is becoming increasingly popular for non-medical uses, including bodybuilding. TRT aims to treat the symptoms of low testosterone, whereas anabolic steroids contain testosterone in much higher doses to achieve bodybuilding effects quickly and easily. TRT can help bodybuilders train harder, longer, and more consistently, and patients who receive TRT experience increased energy, improved muscle mass, increased strength and bone density, decreased body fat, and elevated moods. However, TRT has few proven benefits for people, especially those who dont have low testosterone levels. TRT is contraindicated in men with untreated prostate and breast cancer, and men on TRT should be monitored for side-effects such as polycythemia, peripheral edema, cardiac and hepatic dysfunction.
