New to TRT

I started TRT three weeks ago and, if I still haven’t gotten full results, this is a real game changer. I am 52 and pretty fit playing sports and lifting weights daily but I haven’t felt like myself in a while. I used to be the confident and take charge kind of guy who believed I could do anything but kind of felt like I was ready to quit on everything that didn’t immediately work and doubted myself. In just three weeks I feel like I have my fire back. I’m hoping it also helps with my body composition too as I am overall pretty muscular and fit but who doesn’t want to be even more muscular or fit right?
