I'm 35, I had similar issues. Tested my testosterone, it was at 290 ng/dL. Went on TRT, my tests since starting have been from 650-1050 ng/dL. Night and day difference in energy, focus, emotional regulation.

As a bonus, it helped slightly with body composition and strength.

Glad to hear it helped. People think it's all about muscles, but the mental effects are very significant.
