All I can definitely say for sure is that I feel like I'm in a better mood these days.  Happier.. less stressed out... more relaxed.  I trained at a gym for years, off and on, and always quit because I was never getting anywhere (with 227 test, now I know why).  I got back to the gym two weeks ago so I'm curious to see if the higher test levels make any difference.  I'm just not feeling that "night and day difference" that so many users here are experiencing.  I still have issues with ED, though not as bad as before.  Used to take me forever to orgasm and that's been improved somewhat.  Had mild gyno prior to starting TRT... even now the little bump gets painful every now and again which made me wonder if I should increase Arimidex.  Haven't been sleeping well this past week... like I constantly have the equivalent of 3 cups of coffee in my system.  Maybe it will take some time for everything to balance out now that more of the numbers are starting to make sense.  You should have seen some of my last test results.. sheesh!
