22 Y/O with Low Test and High Estradiol

KSman, I got my bloods done 6 weeks after my last test. I have been taking 1.25mg of Letro Every 3rd day.

These are my numbers from 6 weeks ago

LH - 2 IU/L (3-20)
FSH - 5 IU/L (3-20)
Oestradiol - 163 (Optimum is 80 according to your numbers KSMan)
Free Testosterone (Calc) 200 - (150 - 700)
Testosterone - 9 nmol (10-33)
Sex hormone Binding Globulin 29 (13-71)

These are my numbers today

Prolactin - 11 ug/l (<15)
LH - 11 IU/L (3-20)
FSH - 10 IU/L (3-20)
Oestradiol - 69 (Optimum is 80 according to your numbers KSMan)
Free Testosterone (Calc) 666 - (150 - 700)
Testosterone - 27 nmol (10-33)
Sex hormone Binding Globulin 28 (13-71)

So then as you can see a massive improvement. Does this mean I will just take Letrozole for the rest of my life, get bloods done every 8 weeks and I am good? I take it no need for TRT at this stage and there is no way I will ever be able to stop taking Letro?

Thank you once again KSman!!!
