Taking a blood test from over one and a half years ago, especially if you are having no negative symptoms, and using drugs to “optimize” your hormones sounds like horribly bad idea to me.
No one can tell you where your “optimal” levels should be.
Your levels can be and likely are very different than mine or KSman’s or anyone else’s.
Are you having negative symptoms that you are concerned about your levels and that is why you want to manipulate them?
At least take another test, see what sort of trend lines are developing.
If you are physically feeling “good” note your levels for future instances where you aren’t feeling well and you can then see where your individual balances may be out off.
