Keep in mind it is not an exact reading of those levels, just a general indication. And everybody is different and reacts differently to the same amounts of the same things. The levels of those can change pretty quickly too when you are using supplements like that. And if other neurotransmitters are low it can have the effect of making other ones that arent more powerful, if I understand that correctly. Thats a whole new different ballgame.
