It's 650 mg per serving. Beta PEA, CDP-choline, and 5-htp are the first three things on there. 5-htp is likely dosed lowest out of the 3 but I wouldn't be surprised if there was about 100 mg of it in there, might be more even. CDP-choline isn't exactly cheap either.
Also when I say expensive/cheap, I'm saying it relative to what most other ingredients in products typically would cost. There is a reason why preworkouts, particularly concentrated preworkouts are everywhere, that chit is as inexpensive as they come in terms of producing.
