Research  
Recent studies have highlighted the efficacy of testosterone therapy, particularly when administered via the intramuscular or subcutaneous routes, in addressing conditions such as hypogonadism and age-related decline in testosterone levels. Research indicates that proper administration can significantly improve symptoms and overall quality of life for patients.  
  
Education  
Healthcare professionals play a crucial role in educating patients on the appropriate use of testosterone injections or gel formulations. Proper education ensures patients understand how to administer the medication correctly, emphasizing adherence to dosage instructions to maximize therapeutic benefits.  
  
Testosterone (intramuscular route, subcutaneous route)  
Testosterone is available in two primary forms: intramuscular (IM) and subcutaneous (SC). The IM form is typically administered as a suspension, while the SC version may come in gel or patch formulations. Both routes offer comparable efficacy, though personal preference and medical advice often dictate the choice.
