I've only used patches (and very low dose with no anti-androgens, to boot), but hopefully one anecdote will still be useful : I haven't been misgendered since 6 months into HRT, and I'm a 42DDD now. 🙂
I don't know that brand of patch, though, so I'll just second the advice that some work better than others - and AVOID the generics if you can. (The Vivelle patch I'm using is tiny, about an inch square, and sticks very well.)
