So today I tried out two tablets of the supposed nootropic "Cavalier - Gentleman's product - Daily Cognitive and Stress support.
I popped two pills, waited and didn't really notice any marked brain function increase or tingling as I have with other products. There might have been a slight increase in brain function but it would have been distorted by me finishing my half-drunken can of my Monster energy drink shortly (30 minutes or so) after digesting the two tablets.
My brain was thinking more rapidly but primarily due to the energy drink I believe.
I will have a more controlled test tomorrow when I wake up. I will report at the end of the day.
