Fingers crossed your bloods show a decent change, but be wary it can take many months for hormone levels to change, that's why I do them 6-monthly.
As you don't take oestrogen, EGCG could be a great addition to the RR and has lots of other health benefits.
Personally, I don't believe the hype around 6-month point of no return, the only thing I'd say is no matter what regime you are on, you get to a point where your own mind says 'right this is what I want', to me that's the point of no return

Good luck with the bloods.
