What are the statistics behind the effectiveness of LIMITLESS as promoted by Adam Ringham?

Adam here. Based on the content you referenced, LIMITLESS is described in terms of intended benefits (focus, learning speed, recall, “getting more done in less time”), but there are no specific statistics, clinical trial data, or percentages shown in those posts.

Because of that, cannot honestly quote effectiveness rates, success percentages, or scientific outcomes for LIMITLESS from this material.

Are you looking for scientific studies on specific ingredients, or for user testimonials and reviews?
