Your test is in the normal range, you feel good, good sex drive, seeing gains...I don't think you need to worry about it right now.
This is quite a good point, which confirms what I have said before - low T is far more complicated than just low testosterone levels as seen in blood work. You also have to pay attention to how you feel, and the symptoms. If blood work is the only thing suggesting that you got low T, then I would not worry all that much, since this is not enough for Low T diagnosis.
