Anyone got tips on how to grow my chest so i can hide my pectus excavatum?

[chuypsl]

I know you can’t fix it unless you get surgery but i don’t really want to get it and i feel like gym is enough, i have been going to the gym for almost a year now and i have obviously seen improvement on my chest but from the sides and if you really look at it form the front you can really see the hole, should i hop on gear to grow faster or is there any extra muscle group that could potentially affect?
