From what I’ve read - Trt for someone who is truly suffering from low T symptoms… will help with
libido
Exercise recovery
Energy
And sense of well-being
That being said - if you are not putting the work in with diet, training and general health care, then why would you expect it to work ? It gives you the ability to do these things but you have to put in the work and get them up to a healthy level. You can then optimize your health. Testosterone works ! They don’t use it in professional sport for no reason and risk there careers … but if you have underlying health conditions or deficiency’s then it’s not the only issue that needs attention …
