That study was based on 0.76 grams of protein per pound bodyweight. You're taking in 1.16 grams her pound. It's far above recommended levels even for training intake.
Protein is safe when used properly. It's in food, it's natural to the body. But, too much of ANYTHING can be bad. You can take too much calcium, overload on any vitamin and protein is no different.
Just be careful, man.
I take supps too and can't stand when people who have no clue say "protein is bad for you" and think Creatine is steroids, but you have to use things safely too.
You can even die from drinking too much water too quickly...and nothing is bad about water...until you get too much.
But, it's OK. Your liver is going to explode before your kidneys.
