Although I don't usually advocate it, I think in your case a blood test to measure your testosterone levels may be wise before commencing a trial of Testosterone replacement Therapy. Also you would need to have additional symptoms like low libido and few or no morning erections to support a diagnosis of testosterone deficiency.
All of this said, the only way to know if TRT is going to help you would be to try it. You know in a few weeks. Your real challenge may be to find a doctor who will prescribe it. On no account purchase anything in this line on the Internet.
Hi,
Some of your concerns like not putting on weight or reduced facial hairs etc. are quite common at your age and you have still time for such developments. Again the second part of your post looks normal.
However, since you are worried about your body developments, the best thing you should do is to consult an Endocrinologist for a professional advice. The doctor would decide if any short term T supplemention is required for you or not.
