I thought carbs increased Tryptophan availablility in the brain?

Not during exercise, but in a resting state yes. Here is a great paper on the matter. I suggest anyone who considers dosages of intraworkout BCAA’s over 7 grams highly effective in improving performance versus carbs read this. I’m still playing devil’s advocate on the matter for what it’s worth.
