If struggling with possible low testosterone symptoms, make an appointment with a knowledgeable physician. They will evaluate symptoms, examine medical history, and order blood tests to measure current testosterone levels. If clinically low, the doctor can then discuss options for customized testosterone replacement regimen including gels, injections, patches, and pellets based on the patient’s needs and preferences. While initiating TRT takes some trial and error to optimize dosage, most men start feeling gradual but significant improvements over 1-2 months.
