I considered posting this in the TRT but, though it would be better discussed here. I can not seem to find the links I had but, I was looking at graphs that showed a decline in average testosterone levels in men over the last few decades. Something over a 200 ng/dL difference.
-Has there been any research as to why this is?
-Why not "supplement" using TRT to get to optimal levels? Yes, your body will stop producing it's own but, if you plan on keeping up this active lifestyle would it not be a good idea to keep levels optimum starting at around 27-30 yrs of age when naturally they begin to decline?
**Obviously all especially young guys should focus on diet/training to get to their optimal levels in the first place unless TRT is medically required.
