Test Levels

Ok, I know that for an average male a good test level is 700 and above…over 1000 is great.
My 28 year old male friend is a bit sad that his test results only came back at 535 which I’m guessing is a bit low, so I asked him what his free test levels are which are 183. What are the ranges for free test. I’ve also explained to him that test levels vary daily, so anything you guys would like to say to him? What are the ranges for unbound test.
Thanks
