What is normal? There is no such thing. It is very, very down to personal perception. What you can do is learn as much about the surgical procedures available, the surgeons that perform male chest reduction/sculptor, speak with as many guys as possible that have had the surgery and look at as many before and after pictures you can find, both on here and at initial consultation with surgeons you are considering.
Here's a joke, "What's the difference between God and a Doctor? God does not think he is a Doctor!" Seriously, no right minded surgeon can guarantee making your chest look exactly how you want it. It's like getting a new hair style, you know how you'd like your hair to look, your hair stylist thinks they know how you want your hair to look. But no two hairstylists are the same. Different hairstylists have different perceptions, methods and skills. Is this making sense?
All a good surgeon can do is move you from where you are to as close as possible to where you want to be. It's impossible to say what is and what is not a good result. However, I would say that you should be aiming for at least a 50% improvement in your condition. I had surgery two months go and I estimate my condition being about 70% better. I will be going back to my surgeon in a few weeks time to discuss the result and decide if further work is indicated. I am happier than I was before the surgery - he's done a great job. If it can be improved upon, then I will seek to have further work. If revision is not indicated, then I will live with that - it's not the end of the world.
As for healing, on the whole, the initial bruising should have gone by week four. It is often at this time guys can start to work out again, taking it very easy. You probably won't be back to where you were for at least another two-three weeks after that, so expect to wait up to a couple of months.
Even after two months, whilst most of the physical change will be apparent, things will continue to settle and change for anything up to 12 months. Each and every patient is different. There are two people you need to listen to about how physical you can be post op - firstly your surgeon - what he or she says goes! After that, your own body. If any kind of physical activity causes you any pain or discomfort, STOP and give you body additional rest for a few more days.
Hope that helps.
