Its best to get a second blood work done, in the early AM and... I cant remember with or without food, but it seems to make a difference.
Making sure you are going on HRT when you should be is crucial IMO. You seem to exhibit no symptoms either... so I must ask, why even consider TRT?
Please keep in mind, many men function perfectly fine with lower testosterone numbers. Also, recent life events might have resulted in a transiently lower score.
