Dimitriy V. reviewed Qualia Mind
I have noticed a difference but it takes a couple of weeks before you start noticing a difference in your minds performance.
Fantastic!
I've been always a sceptic about anything man-made that goes into the body to enhance mood, energy, libido, etc. but I read about neurohackers in Ben Angel's book "Unstoppable" and I wanted to try. Best decision ever!
