oddly shaped pecs

The more I work out, the more difference you can see in the shape of my pecs. I think it may be attached to the bone differently but I'm curious to see if any of you had a problem like this that was solved? Or if not is there a way to make it less noticeable? Thanks in advance.

Edit: My left pec is perfect, it's the right pec that looks like it's on meth.

it almost looks as if you had a muscle tear that didn't heal properly

what is your chest routine?
are you using machines or dumbbells or barbell?
looks like your left pec is just stronger and bigger, are u left handed?
