Has anyone else experience this?

I only felt that way when I mixed it with caffeine and creatine all at once. I figured it'd be a cool preworkout concoction, but it gave me a huge headache instead.

Maybe you can't metabolize phenylalanine. Better check (if so, it accumulates and causes severe brain damage)
