Already had the surgery. Despite what you may have heard, they have to leave some of the gland when you have gyno surgery, otherwise you will have what's called a crater deformity in your nipple that looks like this:
So the problem for guys like me with the predisposition is if you continue to do something that caused or aggravated your gyno in the first place (for example, having an e2 above 60 if that is something that is an issue for you) you can redevelop the gynecomastia. Naturals are much less likely to redevelop gyno than men on trt or steroids.
So it's not as straightforward as just having the surgery and then you can ignore it. A healthy hormonal balance needs to be achieved or people predisposed to it will end up right back in the same boat if they just leave the underlying hormonal issue uncontrolled. Unless you're dialed in, it can redevelop quickly.
Besides, I have never seen any study showing that aromatase inhibition causes issues unless you tank estrogen. All the studies use huge amounts and crush estrogen nearly to zero.
