Before I started didnt have the full hormone test done only a testosterone test. And my starting test figure was 8.54nmol/L so wasn't particularly high to start but now non existent.
Dude, that's very low. Knowing your free T level would be of interest, but I bet it was very low as well, with a TT level like that. I think it would be best for you to concentrate just on your hormone levels next. And I mean beyond just the PCT. Do your best PCT with the Nolva or Clomid or Enclo, they're all good at increasing test production. Nolva also protects against possible rebound estro induced gyno the best out of those 3 SERM's. And don't be afraid to extend your PCT to more, than 4 weeks, if blood work for example indicates the need.
If after a proper PCT and time off of everything has your test levels drop to that kind of low numbers again, like you had pre the Osta run, then it would be wise to try and see, if your lifestyle needs some modifying, like sleep, nutrition etc. And if you can't find any lifestyle tweaks, that imrpove your hormone levels, then maybe it's time to take a look at TRT.
8.54 nmol/l = 246 ng/dl for folks more accustomed to ng/dl measuring unit.
