Nolva... I would avoid it long term, though I have read some accounts of men using it as HRT. I personally would not though.
You have several options besides quitting TRT though.
1 - Lower your dose
2 - Switch to sub-q microdosing, 5 to 7 days a week
3 - add a DHT compound like masteron at low dose
4 - give compounded
CREAM a try, 20%, not that 1%
GEL stuff
That last one worked to crank up my DHT and keep E2 middle of the road. Gyno simply can't form in that environment. LOTS of people will say "the creams don't work SQUACK!" yet
the proof, at least for me, is in the blood work.
That said, any of those first three, alone or in combination, are excellent choices, too.
Just noticed in your OP you said:
I added the emphasis there, but were you on some other TRT therapy prior?
