Every ingredient. Every reason.

No fillers. No fairy dusting. Every compound at a dose that actually works.

Ingredient 01

Citicoline (CDP-Choline)

Neural energy & dopamine signaling

Citicoline is a two-in-one compound — it metabolizes into both choline (acetylcholine precursor) and cytidine (which converts to uridine in the brain). The result: faster neural firing and sharper working memory within a single session.

250mg
per serving
Ingredient 02

L-Tyrosine

Dopamine precursor under stress

Your brain burns through dopamine, norepinephrine, and epinephrine during high-stress cognitive work. L-Tyrosine directly replenishes these catecholamines, maintaining peak mental performance when it counts most.

500mg
per serving
Ingredient 03

Caffeine + L-Theanine

The clean energy stack

The 1:2 ratio of caffeine to L-Theanine is the gold standard nootropic combination. Caffeine blocks adenosine (fatigue signal); L-Theanine eliminates anxiety and jitter, leaving pure, focused energy.

100mg + 200mg
per serving
Ingredient 04

Lion's Mane Extract

Neuroplasticity & in-session focus

Even at a single serving dose, Lion's Mane supports acute cognitive enhancement through its erinacine compounds, providing a noticeable sharpening of attention and working memory during your session.
