What this protocol does

Evidence-based nootropic stack combined with focus habits for sustained mental clarity, memory, and creative output.

What to expect

Synthesized from research on this protocol's components. Individual response varies.

Week 1

Look for: Sharper focus and steadier alertness within hours of dosing — caffeine plus L-theanine produces moderate effect sizes for attentional switching accuracy and Bond-Lader alertness within the first two hours post-administration.

Not yet expected: Big gains in raw sustained attention from the caffeine plus L-theanine combo — effect sizes are smaller for unisensory and multisensory attentional outcomes.

Backed by 1 study

Acute effects of tea constituents L-theanine, caffeine, and epigallocatechin gallate on cognitive function and mood: a systematic review and meta-analysis.

Weeks 4–8

Look for: Cerebral creatine stores rise on consistent dosing — research in human subjects with quantified pre/post measurements shows creatine monohydrate supplementation significantly increases brain creatine.

Not yet expected: Cognitive gains specifically attributable to creatine are not directly demonstrated in this stack's claim set; benefits in the broader literature are mostly in stressed or sleep-deprived populations.
