Can you tell me any sort of testosterone help at 17?

17yo or 45yo?: You're listed as 45yo vs your question re 17yo. Regardless, rather than focus on Testosterone, talk to your family doc. There may be other issues that need to be addressed 1st before considering an evaluation for hypogonadism or low T. We need to address root cause of low T before considering TRT or testosterone replacement therapy. We also need to consider (lack of) desire for future fertility.
