Testosterone is pretty volatile.
If is often a snap shot of your current lifestyle. If your a 570 look at your diet, hydration, training and sleep. If they are all on par if you have any disruption in them.. you will probably see your testosterone drop. If all of those are garbage at the time of your blood work you can definitely bring that up.
The benefits of testosterone optimization or replacement therapy as they call it.. is your testosterone will pretty much be well above normal no matter what you have going on.
If you remain natural you will need to train much smarter and prioritize rest and recovery as you age... or again your hormones can take a hit.
I am on testosterone and do not think I could maintain my quality of life. I wake up most mornings at 330... get my workout in and cardio, spring and summer I play in an adult baseball league.. I also golf competitively. So I am often performing 4-6 hours of physical activity a day.. plus working full time. My last “natural” year was when I was 38 years old and I was struggling.
Testosterone let’s me recover like i did as a teen. My sleep is much better, sex drive is crazy... strength goes up when I want it too... fat melts off when I am cutting... if you have the money and go thru a doctor it will definitely increase your quality of life.
