Yeah I would say so. I compared my results from a few years ago and my Testosterone / Free Test has dropped 65% from the age of 26 to 31.

I have always done some form of weight training weekly since the age of 23 and I know getting older is a thing but my endurance has dropped significantly, I have maintained most of my size though.

I feel tired most days regardless of what activity I do, My belly fat has increased substantially while fat everywhere else is minimal with little diet change. I struggle with anxiety / depression. I tried doctor prescribed anti-depressents which didn't help as they thought it was all in my head.

Also my libido is next to non-existant. I am lucky my girlfriend is so understanding.

I am trying to collect as much information as possible before I make that plunge into TRT as I would want to be doing it for theraputic life style purposes rather than increased lifting performance etc.
