It is definitely more than the standard dose. I was already taking 5g for weightlifting purposes. After some of the studies suggesting mental benefits I titrated my dose up to 30g (the high end of the studies). Just added an additional 5g per week until I hit 30. I add it in powder form to my daily protein shake-- usually in the morning. While it could be a placebo, I personally feel there's a noticeable difference. I buy in bulk so it ends up being less than $.90 a day to dose at this level. It's an extremely cheap supplement.
