My surgeon usually asks patients to stop one week before the surgery. Also, you might want to know this ahead of time, depending on what type of hormones you're taking. If I'm not mistaken, from what I gathered in your other posts, you don't live in the US, so I don't know which type of T you're taking, but I am in Europe so my injections are every 3 weeks, meaning that I had to stop T a whole 2 weeks and a half before top surgery.
I'd say definitely ask your own surgeon/their office about this if you can.
And good luck with your surgery !
