The possible hazards of taking testosterone in normal people include the possibility of mental disorders, liver and gallbladder disorders, reproductive and breast disorders, formation of blood clots, and causing prostate disorders. 1. Mental disorders: testosterone consumption by normal people may lead to mental problems, such as hostility, aggression, mental disorders, mania, paranoia and delusion. 2. Liver and gallbladder diseases: some healthy people who consume testosterone may cause liver damage, such as cholestasis, liver damage, jaundice and liver failure. 3. Reproductive system and breast diseases: testicular atrophy, azoospermia and infertility (male), clitoral enlargement and breast atrophy (female) may occur. 4. Formation of blood clots: Testosterone has the potential to cause an increase in blood viscosity, which may lead to the formation of blood clots, but this is relatively rare. 5. Lead to prostate disease: Increased levels of testosterone in the body may increase the incidence of prostate cancer. For patients with a clear diagnosis of androgen deficiency in the body, testosterone can be taken effectively and safely under the guidance of a doctor to avoid the above hazards of testosterone in normal people.
