cory,

You should stop taking the glutamine until your brain has recovered. Even then, you should seriously consider not taking it. It is a precursor to glutamate which is an excitotoxin and is very rough on brain tissue. It may be a part of your continued struggle with concussion symptoms.

It would help if you listed everything to take each day. Also, how much caffeine, energy drinks, alcohol, and artificial sweeteners and preservatives do you consume. They are not good.

Do you work at HD?

What is your goal with body building?
