Clarity
A breath of fresh air. I feel consistently focused.
I’ve moved completely away from my stimulant as it caused consistent mood swings and made me quite scattered at the end of the day. Taking Clarity has been a breath of fresh air. I feel consistently focused (no highs and lows) but not impulsive.

Thesis helped me pass my CPA exam without an ounce of stress.
I used Thesis to help me focus and retain vast amounts of complex information for my CPA exams, and I used the Confidence blend the day before and the day of my exams to help me feel comfortable and ease my test anxiety. Thesis nootropics are like my secret weapon.

Thesis helped me feel focused and clear-headed for the first time.
Motivation and Energy give me the drive I need to overcome my executive dysfunction, it's like my brain is finally... quiet. I am telling all of my neurodivergent friends about these supplements. It's exciting to find something that actually does what it claims.
