I saw from another post you're 25 years old? Did you determine if you were primary or secondary hypogonadism? Unless you have had some type of traumatic injury to your testes, or brain injury that damaged your pituitary, you have something else going on that needs to be addressed. TRT is a long hard road for some (I'm of the some portion), and if you can avoid it everyone on here would suggest to do so at your age.
Read the advice for new guys sticky, thyroid sticky, blood testing sticky. Pay attention to the thyroid labs. Doctors tend not to want to test for the specified thyroid labs. Often you just get a TSH. Also, you need to post all the labs you got on your thread. Hopefully your doctor at least tested FSH and LH, which would determine if you are primary or secondary.
I'm not preaching to you, brother. I'm telling you straight up. Figure out what is CAUSING your testosterone to be low. Low testosterone is a symptom of a problem, not the problem itself. If you can figure out the cause you will avoid a lot of pain.
